My sensor has always worked perfectly until earlier today I was messing around in settings (Display > Horizontal Calibration) for whatever dumb reason I had, I pressed "Calibrate" while I was holding my phone at an angle. Then of course that messed things up, so I laid the phone flat on the table (the blue ball is still off to the side) and press 'Calibrate', it said it calibrated successfully and it brought the blue ball back to the middle during the process. But after it was done calibrating it just snaps back to the side.
*#0*# does not work for me, it simply doesn't do anything
Methods I tried:
Deleting ms3c_yamaha.cfg and rerunning sensorcalibutil_yamaha in terminal
Deleting the two files above and rebooting to recovery to wipe cache/dalvik
Every time I ran the "fix" above, it sets the blue ball in a different corner but never in the middle even when my phone is flat on the table. Even when I move my phone around, the blue ball is stuck on stupid. Like right now, no matter how I hold my phone the blue ball is stuck at the very top middle.
I'm on Serendipity 6.4 hoping to avoid a full flash, does anyone have any ideas? For whatever it's worth, can anyone with working sensors share the 2 files I mentioned above?
/data/system/ms3c_yamaha.cfg
/system/bin/sensorcalibutil_yamaha
Thanks
Nevermind. I fixed the hasslesome problem with a hasslesome solution. i.e. clean reflash, I haven't done that in months! oh well.

Hi guys, hope someone can tell what is exactly with my phone/display.
Long story short – phone fell directly on display, absolutely perfect landing without any rebound, display went nut. Dropped it on back, fixed the problem.
4 days later, display went crazy again and remains broken.
Symptoms: black, grey, coloured lines.
What I can say from usage – they react more on dark colours. If I’m in white background, everything is absolutely fine, sometimes some line appear. As soon as it comes to grey or black, they go wild. They like move for second or two, and then settle, as you can see in the video.

LONG STORY LONG
Seven days ago, it dropped from 1 meter height, and it landed on it’s display, so directly it didn’t bounce not a tiny bit, it just got like glued to the surface. The same moment I knew it’s not good, and I was right.
Display couldn’t get out of sleep mode, when I presed power button I only got a bit of visibility, I could see start button, but if turned it on/off (sleep/wake up) couple of times, display would have normal brightnes… BUT, there were some dark dynamic lines over the screen, as soon as pic moved, they would appear, on static pic, only few would remain. Numerous resets didn’t bring any results, keeping it off without battery, no results either…
Frustrated (It has been like month or two since I’ve got this device), I decided to give a try to traditional Serbian method – hit the electronic device to get it working. I included some brains, so I dropped phone, on the other side (on the back), from some 30 cm height. It worked like a charm! Everything worked absolutely fine!
I could only think of situation that some display contacts must have pulled out a bit, so hitting it back, made them get back into their slots.
And everything was like before… at least for 4 days
Then, without any trigger event, lines came back, and they’re here to stay!
Hard reset, nope. Reset, nope. Dropping it on the back, nope.

There is no one here to make good diagnostics, HTC is like white raven in my country, so can anyone suggest what to do, get new flex cable, get new display?
I am considering opttion to open it up myself, and check are all connectors firmly in place.
Your suggestions?
If anyone experiences anything similar - just reset the flex (flat) cable, everything will be like new
Hi! I am owner of HTC Magic (still android 1.6, no idea how to flash new version ) and i have 2 problems from this morning i woke up.
PROBLEM #1: For some reason i boot from power button and all i see is a black screen with a blue led (this happens 19/20 times). The first time it started up, everything went ok(tried every single button combo, but i found out that it's just a matter of luck)...System was fine,nothing deleted except one little thing...Trackball was not working properly and many times it did anything it wants and had some hard laggy times!
PROBLEM #2: Even the battery is 100%, in 1 hour it's 0% with the phone being able to cook eggs(The temprature goes really high)!
Also, i tried many times to start it up, cause i didn't notice the battary was flat out...Again ~20tries...
Checked solutions here: http://forum.xda-developers.com/showthread.php?t=533240 Nothing matched my problems 100%... :S
UPDATE: I just opened the phone to clean everything.
1)I noticed that the trackball's sensors where REALLY dirty and connectors didn't have a good contact with the board. So, i cleaned them (i disolved it whole) and trackball works fine but up and left is not working at all(maybe i placed the sensors wrong?)...
2)i found out some sand (damn vacations in beaches...) over the battery board and now it works perfect!
3)I still haven't figured why blue led lights up on power up effort...
Any ideas?
Please i need some answer so i retrench for new phone...
Hi guys
I have this strange behavior going on in my Sentation.
Out of nowhere my phone started to have strange screen behavior... Didn't light up after pressing the power button (had to phone my self in order to get screen on).
The next thing was that suddenly the screen goes to maximum brightness or goes to minimum without any explanation (tried both auto brightness or manual).
After that I noticed that the screen went off when I was using it but when I pressed the left side of it it lighted up and off again... making me think of some kind of bad contact underneath. As I already had changed a broken touch screen for t3 times, and let the phone fall for several times I thought it had to do with some plug out of line...
I disassembled the phone completely and mounted up back again. The thing is that the phone started to freeze every 5 minutes (screen on but completely freezed. I have to pul out battery). Sometimes it freezes even in the recovery menu. I've tried several rom's with full wipe and not installing anything and its all the same.
Some times I still not that the screen goes off during the freeze but when I touch the left side it goes on again, but that doesn't change the freezed state even that I let down the phone for several minutes.
I disassemble the phone again, tried different back cover and different battery (one stock and other extra strength) I tried also all the suggestion related to the small pin in the back not connecting well with the back cover (adding an aluminium foil, pulling the pin out, etc..)
Nothing seams to resolve anything so I have clearly an hardware problem... but I don't know what to replace or where to look the damage!!!
Can anybody help me please?!
Update
I have an update on my problem:
I noticed that when I leave the phone on top of some kind of metal part and don't touch it it works all day without any problem but, as soon as I start to touch the phone, it freezes within minutes!
Could it be some kind of static electrical problem? How to resolve it?
I would apreciate any help
Thanks
dropped my tf101. Now when I try to boot the katkiss revolving circles dont stop going round and round. I am able to get into twrp though.I am aunable to restore because I never did a backup. Also I was getting red artifacts all over the screen. I would lightly tap the underside of tf101 and it would make the colors change dramatically on the screen and show red lines going across the screen. after tapping the tablet a couple more times the display colors are normal again but it still wont boot. What can I try?

If you can get into TWRP you need to download the latest Rom and Gapps to a PC and install them onto your sd card) assuming you have one - if you don't ? my advice is get one (or two or three). Put sd card back into tf101 - boot to TWRP and then wipe all (see page one of the KatKiss 4.3 developers topic on this for exact wipes - oops just took this from Timduru's page
Go to recovery
Make a full wipe / factory reset (you can skip this step if you're already on KatKiss-4.3, if ever you encounter a problem do the full wipe and try again before reporting )
Format /system
Flash the rom
Flash optional kernel
Flash gapps
Wipe cache/dalvik
Reboot
As to the flashing of the screen - the fall could have done something to the video drivers hardware (but fingers crossed)
Good luck
Ziggy
after putting in my micro sd card i saw there was a back-up on it. I was able to restore from it and boot successfully. However my colors were off. . shaking/flexing/jolting the tf101 results in things like the whole screen turning blue green with lines across it. I'm not seeing any red lines anymore and now the olor red is missing all together. This makes white look blue and red look black. I was able to confirm HDMI out to tv still produces image/colors correctly. I'm afraid hitting tablet anymore won't bring red back and kill image entirely. Now since its fall yesterday a light tap on TF screen results in screen to go dark momentarily. Any chance this can be opened to fix missing red? Another problem since fall is vol down button is not functioning right. Seems like its stuck depressed. Is the vol down button necessary for advanced options?
Everytime I reboot I get bootloader white text in the top left of screen thats only supposed to show when vol down is pressed. Then the next screen says press down -vol for wipe option but I it doesnt move when i press vol- ( however I think I can actually initiate a vol- button by flexing the pad. Sounds strange right? Anyway I gues that means I can pick the wipe data option from that screen if i have to. after that select android/ data wipe screen I notice now every time I boot up in bottom left it says "SAFE MODE", what does that mean?
Your VOL buttons are stuck down. I am not excactly sure how to boot to safe mode, but it is due to one of the VOL buttons being pressed during the boot up process.
I would suggest taking the bezel off and trying to carefully bend it so the buttons move freely. I wrote a guide for it here: http://www.transformerforums.com/fo.../10501-rs-guide-power-lock-button-issues.html
I was able to unstick vol-, but after hitting tab a few more times trying to get red back, now there is nothing on display. I confirm hdmi output is still working. Anyone service these? Otherwise i guess i get a bluetooth keyboard/mouse and use as desktop PC?
Something i can fix myself by opening?

Most likely it is a loose video or backlight cable. Open it up and take the bezel off per the guide I posted. Then remove the back cover. There is one screw on each corner and then 3 on to and 3 on the bottom between the screen and back cover. The video and backlight cables are in the middle near the charging port. Make sure they are properly seated. Power it on reassembled to see if it works.

I can tell you that when i press power rhe screen does light up. Its just grey screen. Does that mean back lighting isnt the problem and im wasting my time opening tab?

That means the video cable is loose or that the video card is bad. Since it works via HDMI, it should be a loose video cable. The video and backlight are separate cables.
I tvook the case off. Im not sure what to do. Ive got some basic colors on pad display again but it wont boot. Circles still spinning. I cant ssem to enter twrp either. I tried holding vol down power ro reboot and i quickly see green label on bottom of screen and then goes dark. Would twrp be visable from hdmi out?

Here are some pics I took on the bottom side by charger. what should i reseat. Nothing seems movable .can you tell me how i can get into twrp since i currently can't boot. I tried holding vol - and power but i didn't see opption to hit vol +. I tried to hit vol + anyway but i just got a grey screen. I tried holding power vol+ for 10 secs. to cold boot. still just spinning katkiss circles. Do i need to get into APX mode (hold VOL UP and POWER for about 10 seconds and use EasyFlasher to re-flash TWRP?
Bumping thread
What button combos can i try to get back into twrp since i currently cant boot or enter recovery? Is it the multi color wire ribben that i should be adjusting?

I believe this is the display cable that tends to come loose after being dropped, if not that one, a similar coloured and positioned cable, I did have a video showing the exact procedure but can't find it atm
EDIT - Found it

thanks for the vid. I was able to get display working again including red so this will work even if the problem is your display stops showing all colors and starts showing lines and other artifacts. It seems I answered my own question. you cant use twrp with hdmi only. native display only. Although it could be the commands would still work though you wouldn't be able to see what your doing i'm guessing? so in twrp i did a second recovery of my 4.2. katkiss backup since dropping my tf since I was again just getting spinning circles when booting and I'm now able to boot again. Hopefully this doesn't keep happening where tf wont boot and I have to keep recovering. Seems like dropping it may have done more than mess with display?
So my phone screen will no longer display anything. No boot screen, no nothing. The software is running back there just fine, but I can't see it. Could this be a software problem (display driver got corrupted or something)? If so, would someone be willing to tell me the best way to reset? Is it more likely hardware failure since I see nothing during the boot?
My set-up is as follows:
Recovery: CWM v14.4.6
ROM: EMBRYO 6.10
Rooted, debugging on, titanium backup installed
Any help would be much appreciated.
I think I may have found my answer. The screen has been working intermittently today and sometimes appears tinted red, green or blue. Looks like it's time for a new piece of hardware :-/
For anyone else having a similar issue: screen stops working completely, works intermittently, displays with red, green or blue tint, or displays an inverted screen, my problem seems to be a loose connection with a simple fix.
I followed these instructions: http://forum.xda-developers.com/showthread.php?t=1540425 through prying off the back shroud (the one held on by 7 screws). I believe the screen connector is the one on the left in the picture, just below the power button (visible in the picture between steps 4 and 5). I disconnected this (gently pry up), blew off the contacts to try to remove any dust and pressed it back on. I then put a small rectangle of masking tape in the corresponding location on the plastic shroud (mine already had a rectangle of black tape in this position) in hopes that this would help keep the connector securely pressed against its mate on the board. Finally, I snapped and screwed it all back, and so far so good.
My guess is that this problem/fix probably applies to more than the galaxy s II skyrocket - possibly it will be useful to someone someday...or maybe not.
