A couple of days ago I too became the victim of the evil Pronto conspiracy, the touchscreen died on me. After I found this topic I started taking the thing apart to look for the 4 contacts to clean. I took the whole screen off to make sure I would find them, but unfortunately ….. no 4 "O"-ish shaped contacts.
I've made a closeup picture of the top right corner of the screen and was hoping that one of you guys can tell me what to do next.
I really like the remote and hope that I can like it just a little bit longer ;)
Cheers.
ps. For the record, the stickers at the bottom say: TSU3000/01 3104 207 13411 0P00 0328 01248 C3 S/N: 73640063
Clean is a wrong term to explain this. The ribon that is coming out of the touchscreen has 4 leads. The problem of missing contac occurs between the ribon and the glass and you cannot access it.
Some people get an needle and perfurate the ribon in the 4 points that is touches the glass, in some cases the perfuration make the cupper in the ribon re-connect with the glass. It'not definive and sometimes just do not work and you have to chance the hole touchscreen.
I must have the LONGEST lived TSU3000 of the bunch - but have finally succumbed to the fatal "Numb Screen of Death". . Dead, Dead, Dead. No poking, pressing with knives, buffing of contacts, separating of strips will help. This thing is DEAD. TOAST. BRICKED. . Philips is legendary for their non-existent customer service, and while I have enjoyed the flexibility of being able to program my own touch screen, am quite afraid that were I to be stupid enough to choose another Philips product, I would once again get burned in the end. Even dropping $150 on E-Bay to get a TSU3500 would probably be foolish at this point, as it has the same screen, and one can only expect that it too will die after exposure to a humid environment. . I've read of other Philips touch screen enthusiasts dismay at trying to downgrade to the Harmony products. And I certainly don't look forward to another programming marathon to re-create my TSU3000 screens on a new remote of any kind. . What's a poor boy to do??
Awesome - I was panicing my RU 950 was dead and struggling to find a replacement for it with touchscreen and sensible number of buttons. Found this thread, and a few pin pricks later I'm in business again (no bets how long for I guess though). Thanks guys!!! Jeddy

I posted my first message here creating a topic for my problem before I find this thread and discover that this issue was not only mine.
So I tried the solution of the puncture trick but I don't know why I'm the only one this is not working. I'm still stucked at the third step of the calibration menu (top right), wherever I touch the screen. I tried with a needle, with the head of a very fine screwdriver. I tried an eraser ... Do I have to scratch the sort of plastic layer above the 4 marroons square point in order to get rid of it ? Thanks for the help and cheers to all of you guys
I am glad I found this thread. My 3000 died tonight and after several resets and firmware retries I finally took it apart and used a sharp knife to prick the LCD edge connector. It works great! I made a short video to show the connector.
I have just performed the surgery on two TSU3000s. We have had an unusual Spring and Summer here in Denver, with extra rain and humid days. One client also installed a humidifier about a year ago. Perhaps two different clients with failed Prontos of the same model in one week is due to the humidity. I used an X-ACTO knife blade to puncture and slice the LCD terminals, then sealed with dielectric grease from an auto parts store. So far both remotes are operating normally again. The YouTube video was enormously beneficial. Thanks to all.
A big thanks to those who figured out how to fix the unresponsive touchpad. I got a TSU3000 from ebay and yikes only the hard buttons worked. I pricked each of the dark brown contacts with a needle a couple of times and now its working nicely. I worry that living in a humid place will mean the fix won't last long. I have seen one report of 2 years. Any other data out there. I assume the other models don't have this issue as I haven't seen reports on this site.
A few years ago, I had this same problem. I fixed it by removing the touchscreen flexi, soldering 4 mod wires on to the main flexi, then I fixed them onto the touchscreen using epoxy. I then used conductive paint to make a connection between the wires & the silver tracks on the touchscreen. Worked great until the screen was cracked a few weeks ago :-( Good news though, I have now fixed it again, details in the next post.
I have sucessfully replaced my cracked touchscreen using a cheap Hp iPAQ 1940 h1940 1945 h1945 Touch Screen from ebay. The item number was 190557941601. The cost was less then $10 delivered from Hong Kong. I had read in other threads that the cheap Hong Kong touchscreens don't work, but this works perfectly, I didn't even have to calibrate it. Fire seperate the remote. Remove the display from the main PCB, it will be necessary to desolder 2 solder joints. Carefully remove the old touchscreen from the LCD by prising it off the display using a knife & clean of old adhesive. Remove protecting layer of new touchscreen, exposing the adhesive & attach onto the LCD, taking care to align correctly. Check alignment my placing blue casing over the touchscreen. Note that the touchscreen is slightly smaller then the old one, & some of the border will be exposed withing the display window. This isn't a problem. The hardest part is soldering the touchscreen flexi onto the main remote flexi, not a job any DIYer is capable of I'm afried, but using a large flat spade tip that covers all four joints will do the job with care. Remove the old flexi by heating carefully, apply a little flux. Tin the new flexi, offer up to mating flexi & apply heat using the flat tip spread over all joints. Timing & temperature is crucial here, not enough & the joints won't bond, too much & the flexi will melt. Hope this helps someone.
I bought a refurbished TSU3000 in 2006 as a backup. Recently my TSU2000 has been acting, turning on - off by itself and draining the batteries every two days or so, I took out TSU3000, recharged and keep getting a failed calibration. I have downloaded and updated the firmware from newest to oldest versions and back but never pass the calibration screen at any version of its firmware . I want to open it up but there is no torx screw! I think it's glued since it's a refurbished. Anyone has a similar problem? how to open without breaking it...? Any advise? Thanks much. An (Lesson learned: use it when it's still in warranty!)
