Question about Philips PDAs

Open Question

I have a pronto TSU7500 remote. Suddenly the backlight stopped working. The hard buttons and the touch screen work fine but I cannot see the touchscreen. It is fully charged. Any suggestions?

PDAs that use touch screens have a very thin membrane over the screen itself that responds to pressure. If this membrane becomes damaged, which it sounds like what has happened, then you're more than likely going to need to have it replaced. You can try doing it yourself, but it's WAY up on the difficulty factor because of the complexity of the connection to the circuit board on the Vx.
To determine if your unit is, in fact, actually damaged, you should first make sure that you've syncronized the unit (which may not be possible if you don't have it set to automatically activate HotSync when the device is attached) then do a "hard reset" to restore it to the factory default. To do this, hold the reset button while simultaneously holding the power button for, at least, three seconds. You will get a message asking you to press up on the control pad to reset to factory defaults. Once the unit is reset, try the screen again... touching even the outer areas to see if there's any response. If it reacts, or beeps at all, then it may be an issue of recalibrating (using the "Digitizer") once it's fully reset. If not, it will need repair/replacement.

SOURCE: Touchscreen does not respond to touch

Thanks, Your the best! I love my old beat up Treo 600. Everytime something goes wrong I panic, buy a new phone, and then find a fix for the Treo. This was a corker
I had exactly the problem listed. Taken the phone apart and put it back with no luck. After this post I took the Treo apart again but removed the Screen Saver and cleand all of the surfaces. Back together and BINGO! I'm in business again. The only problem now is what do I do with the HTC Touch Cruise on the way? Thanks again.

SOURCE: Touch screen not working...

Hi guys,

i post this solution for those wo will be in the same situation in th next future. I had the same problem with my HTC TyTN (Herm 200). The touch-screen was simply not working. I read many 'solutions' on the net but none worked. I did not try the hard-reset because i was convinced this is not a software problem, and resetting the WM5 will not help. So i brushed the corners, looked for small particles which were pressing on the cover of the touch screen. but it did not work. finally i found one post (i don't remember where exactly) where a guy used a credit card and pushed it all around the touch-screen under the metal case (a bit harder). i tried it and it worked. i pressed harder especially in the lower part, above the buttons. and simply it worked ! no problem since then.

SOURCE: My tytn ii touch screen is not responding

I have had the same problem but have finally got past the alignment screen by putting a new text document called welcome.not onto the memory card. At least the phone is working now, but the screen is not. HTC have sent me the phone back wanting £360 because they say it is water damaged even though it is less than 12 months old.

The digitizer is defective and needs to be replaced.

You can find digitizer parts in ebay or other on-line companies, at reasonable prices.

Regarding the labor cost, depending of the repair shop you choose, it may be cheap or expensive.

Also, if you have minimum experience and skills in fixing electronics, you can try it. really is not so difficult.

Best regards,

separtdifge3,

Probably a charge issue, try this:

1. Connect the reader to the computer for 15 minutes (make sure there is a red steady light)
2. Disconnect the reader and press the reset at the bottom
3. slide the power switch to turn it on
4. If the problem persist you will need to do a hard reset
5. If after a hard reset the issue is not resolve problably you will need to contact sony to get it repaires =(

Touch screen not working


You may just need to do a hard reset. Power off the phone and remove the battery. Wait a few seconds and reinstall battery and turn on the phone. If that does not work then you have a hardware issue and the phone needs to be switched out for a new one.

Button stuck?


or course, powercycle....if that doesnt work, a master reset will be needed.....because it sounds like there might be somehitng stuck on the screen in the corner for make it scroll around, clean the screen with a qtip and rubbing alchohol.....if that doesnt work, try a software reset. with the phone off, you will have to press and hold the button withthe lines on them and press the power button.....release the powerbutton.....the phoen should turn on and go to a black screen with white writing....release the soft keys here and press the green call button...it will reset the phone, but in turn, you will loose your info that is not stored on the sim or media card...

this is hard to do, so if you can navigate through the phone go to start, setttings, system, clear storage. it does the same thing. good luck :)

Touch screen suddenly stopped responding!


Make sure your device is not locked. Lock button is the "Slide Switch" lower left side of device. If locked, will show a lock in upper right part of screen. Will unlock when you pull down the keyboard. This is also a very good feature to prevent accidentally dialing when getting in/out of your car etc...To unlock, slide switch to middle position.
