I don't know how much this 3000 unit is worth with the
"frozen touchscreen". Yes, I do have the docking but not
the original power supply, as I live in germany. I have
a universal power supply. I don't know how bright the
backlight of a new unit is, but mine seems to be OK, no
problems to read except when the sun shines directly on
the LCD.
I guess I will look for a "cheap" 7000/980 then! Yes go for the 7000. Much,much better remote. I can ofer you U$ 40.00, for your dead one, w/docking, let me know. I will renew it and resell down here in Brazil.

@ossocao,
The offer sounds interesting. I wait a few more days for the answer of the eBay guy. If he does not answer/offer a better solution I might sell you the thing.
That's just annoying... I would buy a brand new 7000/ru980 if I had the money, but as a student, things must be kept to minimum when it comes to spending money ;)

Ok, Here is swhat I did to fix my Pronto. I disassembled the unit. I completely removed the LCD screen, I CAREFULLY removed the black protective tape from the back of the display and with the aid of a microscope and small soldering iron , I reflowed the solder on the flexible circuit conductor. Before I started I looked for fractured solder joints but I could not find any. They had to be there but I was not able to see them. I'll let you know how this works out, but right now the Pronto is working better than it has for sometime. It had been sluggish for a month or so. As far as doing this repair yourself. You have to have a microscope and a small tip in your soldering iron. This is not for a novice, even a person with years of soldering experience would find this challenging. I have worked with small surface mount pc boards for years and it was still tricky. If you can find someone to handle the soldering work I am fairly positive that you can fix this issue. If not send me a email and we can talk. I don't really want a boat load of these things showing up on my door step. Hopefully this will be a good fix. Time will tell. Mike/KD9RG

Mike/KD9RG This is to fix the non-responsive touch screen? This will not do. What hapened is that you moved the toucscreen ribon and the contact closed again. It will problably stop to work again.

Wow. I bought a Torx # 6 ($1.99) and followed the instructions from post #230 (fransvdmb) for taking the Pronto apart, cleaned the touchscreen, poked a few holes with a needle, and I am back in business!! Thank you remote central, and to the super smart folks who figure out how to solve our Pronto Problems -- Pronto!! Best, -- shootsbooz

I also have Pronto TSU 1000 with a broken screen (my father-in-law) has big thumbs! Do you know if the screens on eBay work with that model as well? I can always use a $36 dollar backup.

backup. Nope. No actual glasstops will work direct. The glasstop from the ipaq 5400 series has the same size, but re-wire is needed since the conector is in the other side and the jumpers are out of order. I Do not recomend if you never did it before.

Hi there,
had the same problem with my Unit. Used for 3 Month and then only the Backlight functioned upon touch. Dissasembled the Unit, resoldered the connectortape and punctured the contacts on the Digitizer unit. So far I´m happy again. Remains the question for how long......
Anyway, thank You very much for this thread. Philips still didn´t show up with a solution? Poor. What would then be when their new Models came up with such a problem? Shame on You Philips in this one.

Just an update on this method:
- It still works after 8 months;
- Do not buy a contact cleaner, but a needle!
- Puncture with "force" each contact spot 4 times.
Good luck. New update on the needle method: It still works after 12 months; - Do not buy a contact cleaner, but a "fine" needle with a very sharp tip!
- Puncture with "force" each contact spot 4 times in different places on the contact square. Good luck

Updated procedure I just had the same problem with my Pronto RU950/00 V3.2.
and could solve it with the "cleaning contacts" procedure.
However there seems to be some confusion about "cleaning
the 4 contacts at the top right of the screen" as there
is no connector or open/accessible contacts to clean.
The touch screen is connected through a flexible plastic
foil with 4 copper lanes, running from behind the screen
and which seems to be glued to the metal terminations
on the glass surface of the touch screen. I found it very
easy to restore good contact by puncturing
the 4 square contact spots several times at different locations with a fine sewing needle with a sharp tip. And the screen works fine now. I have now a 12 month experience of successful operation since the repair. There is a lot of good information to execute this procedure
spread over several posts .
Below I tried to join the main pieces, and remember my
disclaimer: I do not take any responsibility of this fix
- you try it at your own risk! And you need some device
disassembly/assembly experience and a torx tool to execute
these steps !!!!
- Remove the 4 torx screws (size T6) at the bottom of
the Pronto;
- Open the case by runing your fingernails in the groove
and pry it open.
- Remove a 5th torx screw on the top of the circuit board
and remove the circuit board from the Pronto casing;
- Take off the green rim round the touch screen. The left
side can be lifted, but the right side needs pressure
towards the outside (near the mute button) due to a plastic
tab that fits in underneath. (reassemble it in reverse
order);
- Puncture de 4 contact spots 3 to 4 times, at a different location, with a fine sharp sewing needle, applying good pressure to reach the glass surface;
- Connect the rechargeable battery pack, or reassemble
sufficiently to put the batteries in and test. If no success
try to add a few additional punctures.
It worked at the first attempt for me! Good luck
Thanks to bongiornoa, PeraV, and many others.
