Hi folks my other half who has a C600 has complained about joystick issues for a while now so I finally did something about it (sick of her complaining about her 'crap phone' - ungrateful #!&@! ), not sure if this is THE issue with the c600 joystick so would be interested in any feedback good or bad.
Basically the joystick became less and less responsive over time so harder presses were necessary to perform actions. Didn't fancy spraying WD40 in my phone (what does this actually do?) and after testing switch operation with my meter all seemed ok.
What I noticed was that the piece of metal holding the joystick is stamped to a lower level than the rest of the metal chassis holding the keyboard. This section is only supported at one end and therefore, every time the joystick is moved a bending action is exerted on this 'sub chassis'. Hopefully this picture might help people understand what I am on about...

Now I found that by simply bending this piece of metal back up a little bit I restored the joystick to it's former self! No cleaning, NO WD40!
Now just to note I didn't mess around but I suspect the problem might return in time so maybe these phones are missing a bit of support between the joystick chassis and main board? Maybe someone messing about might want to investigate sorting this.
Hope this is useful to someone although I realise it is coming a little late in the C600 lifetime!
I just thought on if I get enough requests I could do a decent photo guide for stripping the C600 and maybe the VOX too.
What I do is clean all the dust out of the rubber piece that's over the joystick in my T-mobile SDA, and then spray the joystick with quick dry electrical cleaner (usually available at your local car parts store).
Hi thecraze, yes being an electronics engineer I am aware of switch cleaner. I realise in my case however this was not the issue, as all switch contacts showed a good low resistance with little effort on the joystick. There was also negligible dust too.
I have also noted that cleaning does not work for everyone, and this may be one of, if not the contributing factor in such cases.
Thanks anyway.

Would a big magnet stick to the bottom of the i-mate 7150?
Would a magnet sticking to this cause any progrems for the pocket pc?
I have an idea for my car but first need to find out if this would be okay...
The HTC Athena has a large magnet in it (and a hard drive) but it works well with no ill effects, the largest problem with a powerfull magnet is when you put the PDA in your pocket, it can wipe out the magnetic strips on credit/ bank cards etc - I have a number of swipe cards that no longer work since getting my Athena!!! - Mike
hmm alright.. i have an idea that i was thinking about..
For any of you not familiar with the Acura Integra, on the dash board, it has a decling indent to show the clock..
now i was wondering.. i would like to but a large magnet under the dashboard before the clock so then i could open up the i-mate 7150 and place in the indentation and not have it sliding around and be held firmly.. i know this may be kind of confusing but for anyone who understand do you see any reason why this cant be done?
here is a picture of the dash board

No reason you couldn't try it - one word of caution though if the car is equipped with air bags take care when working behind the dash - set one off and it would probably put you in hospital.
Check out Brodit for a holder and Pro Clip for the device though, they offer a profersional and safe mount for most devices and cars - a magnet probably won't hold the device in the event of an impact, a heavy phone/ PDA flying around the cabin could cause serious injury - Mike
Ever think of trying something like this?

Hello all
I love my tornado but i have some problems with the joystick ( it become hard to use).
I someone know where buy replacements parts i will be the happiest !
Please help me
PS: sorry for my English ...
Someone already posted such a question and posted back the part number when he found it. Just poke around, it will be in the first couple pages of the forum.
I recommend to use compressed air to blow out any dust &c and maybe use some graphite lubricant (use a hard pencil on a nail file if you simply can't find any, catch it on paper).
Some madman reported using WD40 to good results. I don't recommend that, except as a last of last resorts.
I've tried wd40 and now I have no problems with joy. It works like brand new one
Tanks you for yours answers. I will try WD40 ( I have bottle ).
Also I was incapable to find the part number in the forum. If someone can help me.
I keep you in touch with my WD40 experimentations :d
What is WD40 , i have the same problem with my phone

I tried today wd40 in my phone whitout open it ( i protected keyboard and screen) and it's better but not perfect. I think i will open it, maybe I will wait to find the OEM part.
Other way ?
I see no problem with opening it to clean out any possible dust or crap.
You can buy cans of compressed air, similar in shape/system to WD40, but only shoot air. This will blow any dust out, but you need under the thumbstick to clean it right.
The cans can be expensive, but think of it as an investment. After you clean out your phone, open your PC case and blow out the power supply and the fans for CPU and video card. Dust collects like crazy...
If you are crazy enough to use WD40 (which I do NOT recommend), do:
ensure tht only your stick is being sprayed
clean with a dust free wipe or swab throughly before reconnecting to the mainboard
Works fine with WD40 without open tornado but keep somes problems
Everything fixed with application of "contact" !
This is a spray that you can buy in electronics or sono shop. It use to restore contact in linear potentiometers.
My Tornado word as at first day !
I am working on a wallmount for my TF700 atm, so once entering the door to my apartment i can grab and operate my house automation software with it.
Basically the 3D modell is done in Google Sketchup.

Sliced the modell into a back-, mid- and frontplate, and exported it into a dwg-file which you can find in the zip attachment.

I will use my local carpenter to provide me with the plates and work my way forward from this point. Please be advised i have not had time to cut the plates yet since i am quite busy irl atm.
Some work i still need to finish:
- thin rubberband between the tablet and wood, for easy safe sliding into the wallmount
- charging hole @ the bottom
- the mount system itself, hopefully removeable mayby integrate a kickstand so i can even place it on a table
Questions:
Is there a pin layout for the bottom charging plug, i heared it should also support audio out for external speakers there or can this only be achived by the headphone interface at the side of the tablet?
well done. looks nice
I would also recommend to cut-out a small piece in the top-middle of the back-plate. This will probably allow you to more easily grasp at the device.
Rubber does not make a good slide. I would suggest putting a layer of smooth fabric over the rubber to smoothen it.
Silk or Lycra (Lycra is cheaper) should work. Lycra has a better heat regulation than regular cotton, but normal cotton could work too if you're low on budget.
How will you be attaching it to the wall?
I like this idea!
What sort of home automation do you use? Something similar to Brighthouse Networks?
I find that a heavy duty felt works very well as a smooth barrier between two objects. Mostly, I've used it to keep my wood furniture from scratching the new floors, but the same principle applies obviously with glass & wood. It provides a good deal of padding beyond just the low friction surface, and it's also super cheap to boot.
I was doing a screen replacement on a Nexus 5 and a small part from the motherboard fell off.
3 pictures to illustrate the problem here:
http://min.us/mKOC4FQe6F0HI
Afterwards, the mobile connection was a lot worse than before. Now, 2 weeks later, the phone's connection has become unusable and it constantly shows no service. Only very rarely does it have any sort of connection (Edge/3G/H/4G).
Questions:
1)What is the part that came off? (see album above) My knowledge is a bit limited but I'm quite sure it has to do with the connection? I notice there are 3 other parts exactly like this spread over the motherboard.
2)Can I repair it? Do I glue it back on? Do I solder it on? Does it somehow click on? (I have tried if it clicks but this part is so tiny it's almost impossible to really handle
3)Based on my explanation, do you think this tiny part is the only cause? The phone still had some connection at first but it got worse. I'm also planning to order replacement antenna cables to see if that helps.
Thanks in advance!

In my case.. I had to replace the charging circuit Cuz it was 'broken' as described by the cellphone shop.. It has connections to the antenna.. Now phone is fully working.. Before that though, I tried different sim cards with different companies (bell Rogers and fido) all worked on my phone except my carrier sim card (mobilicity). After replacing the circuit I just mentioned everything works fine. Cost is 25$
Needs solder it's an rf trimmer /radio frequency. It's vital to an ariel of one type or other. If you want to risk a bodge assemble everything except the back and hold it in place with bluetack. If it works I was going to say epoxy it but don't. Get someone to solder it. It's easy to do if you have the skills.
Oh vital it's right way round and has now been turned. There should be a slot for tuning it.
So I bought a replacement screen, it became unresponding to touch within a few days. After sending it for a replacement the new one had the same issue right away. This time I desided to give it a go fixing it myself. I'd like to share with you how to fix this problem.
First of all the problem, the touch screen is not responding; its feeling very warm when you turn on your phone on the left down corner. The left down corner is where the screens hardware chip is located.
There are enough video's on youtube how to dissable your phone; so I will skip that part. Remove the screen and continue reading.
==================================================================================
Remove the copper carefully, try to keep it in one pieces. Its probably a ground field to keep interferences away.
If you dont want to remove the white plastic frame of your screen, you can cut it carefully for a little. Make sure you cut as less as needed and never cut it completely. Don't cut it near connections.

After remove the copper you see an L shape of components, protected for short circuits by an L shape on the copper plate. These are circled with red.
Then also note there is an arrow on the picture, showing there are more conductors, but these are unprotected! Pressing on the screen cause short-wiring here. Fix it by placing some kind of protector on it ( insulation tape or something like that). Place the copper back and assemble your phone!
Thanks. You have resolved a long standing problem with my 1020, two displays later.
For others:
To insulate those exposed components use the proper stuff. Kapton tape. Google it. Sold by electronics suppliers and on ebay.
Also, look carefully at the circuit board for uninsulated vias. Vias are the small holes that join tracks between layers in the circuit. They look like a small gold circle with a tiny hole in the middle. Cover these too.
Thank you so much ! :good::good:
You are a genius
