Treo 750 display driver problem? - Palm Treo 750

I have a treo 750. Its used and I don't know what the guy before me tried to do with it, but it looks like all he did was install the official WM5 to WM6 update. My problem now (and part of the reason he sold it) is that there seems to be some serious screen corruption. I'm inclined to think there may be a driver issue? I cant even see the bootscreen. All I can see are a couple of vertical and horizontal bars (mostly around the top) with a multicolor spectrum. The rest of the screen is blank. Hard-reset, soft-reset, neither works to fix it. Oddly, if I access the device through MyMobiler and regedit/change to font to something that it hasn't used before (ex. calibri, arial) it seems to bring it back to life... still no boot screen, but the os will work fine. If I put it in standby mode and then try and bring it back on, I'm back to the corrupt screen. At the moment I've turned off the power-idle feature and just let it go to backlight off while leaving the device on all the time, but I cant leave it like that forever. Any thoughts? Am I able to update the display driver or something?
PS. Display works on my PC through MyMobiler with no problem.
Thanks in advance.

having exact same problem
I am having the exact same problem. The only way to avoid the display corruption seems, like you said, to avoid putting the phone in standby mode... but then leaving it like that all day will drain the battery very fast, obviously.
I'm curious as to what the cause is. My phone is out of warranty already. Purchased summer 2007.
rjackets, have you done anything since your post?

Hey i Still have the same problem, did anyone find an answer yet?

Is this what you're seeing? http://commons.wikimedia.org/wiki/File:Bootloader.jpg

no, it's like all the 1st vertical pixels get extended to the right end and the lines keep flashing, i kind find my battery atm but it looks something like this texture, just with pixels:

Weird problem with my TouchPro's camera.

I've encountered this weird problem with the camera. The phone is brand new. When trying to take pictures, in the viewfinder and the pictures taken, it was blurry and ghostly, something exactly like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I have tried so many ways including hard-resetting, flashing to new ROMs and whatnot. Still none works. Any suggestions, please, I don't wanna send te phone all the way to HTC Turkey for repair, as HTC USA claims that my phone's serial number belong there. Thank you all.
I had a similar problem with my Fuze's camera. When I would take photos, it would look like static (meaning the image would not come out at all) but it would be colored exactly the way your photo is colored (the greens, purples, and oranges).
That phone also had a dead pixel on it, so I ended up returning it to an AT&T store, and they gave me a replacement. The problem did not exist on the new replacement phone, so i'm guessing its an issue with the camera.

Thank you for your confirmation, I guess I've gotta try to contact HTC then since I've got my TouchPro on E-Bay.

my step dad had this problem on his iphone and he did a hard reset and it fixed the problem but i would say normally if this happens it is a problem with the ccd so i would try hard reset and dont' load any apps if it still does not work then RMA it

Graphics bugging in touch flo, normal?

That happens to me from time to time. Sometimes I'm doing something and it suddenly happens, sometimes it's happened while the screen's been turned off and no programs have been running in background.
So is this a normal TF3D feature, or should I contact warranty services?
The graphics everywhere else are normal, it just seems to affect the TF3D.
Have you tried a hard reset? No that is definitely not normal... try a hard reset. If that doesnt solve it you should probably contact warrenty services.
Mine does it too. It also produces an effect that looks a bit like a 'broken screen', AND sometimes, just for fun, it pretends it's an old analogue TV that someone unplugged the aerial from (ie snow). All have been covered elsewhere on XDA. Mine has been doing it since day one (along with GPS lag about as long as a Nimitz class carrier) and three months later it still keeps on plodding along, annoying the hell out of me, making me wish I haden't wasted £479.99 on it....
On a more practical note, it looks like you have altered your Touch Flo a bit, mine has problems with the bog standard ROM and with customisations to the Manila.
*EDIT* Actually, it looks like your Touch Flo is bog standard so i'll shut up. Ahem.
Hehe yeh, it's the standard TF3D, and yes I've tried hard reset, no help. Sent the phone to the shop I bought it from, let's see if they can do anything about it.
Unfortunately the place I bought mine from doesn't take returns after 28 days. I have funally badgered HTC support into offering a repair, but I have a bad feeling that the will simply send it back and say it's okay (then give me a bill, LOL ; )
I'm actively considering flashing another ROM but can't make up my mind.... Hope the shop you bought it from replaces it : )

[Q] Graphic problems with p5100 10.1"

Hi,
I got this weird problem and im not sure is this a hardware problem or not. For example. when using menus with white background, the background goes partly blue. Sometimes the graphic error is only blue lines in some part of the white background.
but when checking one option in same menu the background turns normal or atleast there is some change in the background. So these errors reacts only when changing options. And theyre always in the same position when going the same menu.
Also when using camera. the view is messed up a bit. there is a clear line somewhere in the picture when going dark to bright. With my english its hard to explain especially when i dont have any idea what is causing this problem.
Below are two attachments that explains the problem much clearer than i can write:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And before you ask. Yes, it has dropped and i have replaced the glass. But i got it with broken glass so i dont know was it like this before it dropped and the previus owner couldnt tell either.
Any possible solutions?
Thank you in advance!
Sounds like a hardware issue, just for the heck of it I would open it up and check the ribbon cable to the digitizer/screen, it could be loose.
Pp.
Checked it. Same problem. Tried to change brightness level, hard reset, rooting etc with no luck.
Its just so weird that in some situations the screen looks totally normal. only these few situations cause errors in the screen.
Hmmm, there are dialer codes that are used on phones that run a series of tests to check screen performance and output, don't know if this can be done on a tablet, but I would research it.
The only other time I heard of this was on a phone that recovered from falling in a toilet, the phone was dismantled and cleaned and assembled and it worked fine for over a year, the only glitch was an occasional color spasm on the screen similar to what you discribe.
Pp.
Thanks for the tip! Need to look for those codes when i get back home. I removed the logic board and cleaned it with denat. alcohol. No visible damage at least! trying to assembly it back later today. I decided to order a new LCD flex cable. Its the cheapest part to change.
No luck with the codes i found. after cleaning still same graphical problems. Now i can only wait the new flex cable and hope it will fix those errors.
Anyways thanks for replys and suggestions. :good:

Lost full screen - black bar at bottom of screen

Afternoon all.
As per title. After installing Renovate 3.0 today, I noticed that I've "lost" about 5mm at the bottom - just a thin black bar under the display.
Thought the ROM was the culprit, but I've reflashed 5 or 6 Rims and it's the same.
I've tried all display resolutions, immersive mode, different themes, clean installs, soft reboots, too many restarts, toggled everything I can think of- the same. All screens, all apps.
Driving me absoeffinglutely nuts. Any help appreciated!
Have you tried flashing back to the factory firmware?
Take a screenshot, does the black bar appear in the screenshot? If not, the display panel is broken, if yes, it's a software glitch

No, doesn't show in screenie, didn't expect it to. Find it hard to believe it's physical damage - never dropped it, Otterbox Strada wallet, but somehow the display is FUBAR.
Seen one similar problem after googling, on the S8, no obvious cause or solution.
Going to wipe everything including system and all storage, flash a stock in Odin and cross my fingers.

Very odd, if it appeared right after you installed the ROM, a software problem is possible. But I still wonder how it's possible for a part of the screen to render on a screenshot, but not on the actual screen.

Graphics Corruption Fault

My two month old POCO X3 NFC 128GB appears to be randomly exhibiting a graphics fault. Occasionally upon screen wake up, this sort of graphics corruption occurs (see first image below)
The first two times this happened, the corruption was blue, the one in the image is red, it looks like a low resolution, low colour mode, and the only way to get the screen to go back to normal is to reboot. I have not managed to intentionally cause the error to appear.
Screenshotting while the error is occurring shows a normal screen without the issue.
Has anyone seen anything like this or have any idea what is causing it? This is my first Xiaomi phone after reluctantly switching to them from three previous Huawei mobiles. Very disappointing and annoying to have an intermittent error two months into owning this phone.

I have indian variant, have exactly this issue.
After updating to 12.0.9 once a while display acts like this.
You don't need to reboot simply go in settings/ display/colorscheme and click standard Display will be back to normal, it's a software glitch which came with new update

Thank you for your message, this very interesting to hear as I have not seen anyone else talking about this and I was beginning to wonder if it was a hardware issue as the fault looks very much like graphics chip corruption. The next time this happens I will try your fix without rebooting to see if it helps, thanks again.
