Hi,
Its been a while since I've visited Remote Central, not to mind reading these posts, but if anyone could help me with my troubled TSU7000 issue I would be very grateful.
I have this unit now well over two years, best unit I ever purchased. The problem I have is on Sunday last I start to watch the last few episodes of Jericho Season 1. I reached for the remote to turn down the volume of my amp. I pressed the - volume button a few time, seem to work fine volume decreased, then the screen / back light froze. Pressed another few buttons nothing happened. Ok I said maybe the unit crashed and just needs to be reset. I left it and continued to watch the final episodes of Jericho and when this is finished I'll whip off the back cover and depress the reset. When I returned to the unit I found that the screen was completely blank, tilted it to see if the back light would come on.. nothing. I removed the back cover and pressed the reset thinking that this would solve the problem... still nothing. I remove the battery and pressed the reset button replaced the battery and still nothing... At the moment its sitting in my PC room with battery removed not working. I'm, as all AV freaks seriously gutted at the loss of such a centrally used item. If any one has had a similar experience and has solved this problem. I would be in your debt if you could share your wisdom....... I've never dropped the unit, no liquids have been spilt on it, I haven't connected it to the PC in over six mouths. its been treated with the respect it deserves. I'm now back to the 15 remotes on the table.... Please please send me your advice.....

Black o white screen? Black? Try to look at the remote under a strong light if you can see the imagem you have a screen backlight proplem os a bad conection in the ribon. If you ara expericinf a white screen, Looks like you are another victimin of the white screen problem. See this: [Link: remotecentral.com]No solution yet. In my opinion a chipset problem for the white screen. Black screen anothe screen can be the solution.

Hi,
I got the same problem as most of you, touch screen died
suddenly (RU 950). As Pronto is crucial in my HT I even
bought a new one (RU950). After that I could start to
analyse the problem in the old one with a good concience!
And alas, I found the fix, which will cure both dead screen
but also the failing calibration (actually the same basic
cause). BTW If the Pronto Team doesnt really know the
problem - I am disappointed.
The nice thing about the fix is that it does not cost
anything, but you have to be able to open the whole plastic
cover system properly.
Disclaimer: I do not take any responsibility of this fix
- you try it at your own risk!
First you have to open the plastic cover system (there
are 5 torx screws holding the upper part, 4 visible and
one inside). After that you may be able to take off the
green rim round the touch screen. When that is done, you
will see a flexible connector (carbon to copper) at the
upper right corner of the touch screen. And that is the
cause of the problem! There are four connection points
(o o o o) which should make contact with the flexible
copper strips beneath them - but for some reason they
lose their connectivity after some time (oxidation?).
So the simple fix is to rub the connection points with
a sharp object (model knife, opposite end of a needle).
Be careful not to puncture the plastic (or break the glass!)
but still use enough power to ensure a good contact...
If only one connection point is faulty you will get calibration
error, if more, the touch screen does not work at all.
If Daniel allows, I could send some pictures to make it
more clear to u all.
Hope this helps, it surely helped me - :-)
regards PeraV Just wanted to say thanks for reminding me of this. Just cured a tsu3000 that was all messed up. Your info reminded me that when i took the unit apart i did notice that on the back of the lcd panel (on my model you can't seperate the lcd part from the circuit board without desoldering 3 points, which i didn't want to mess with) the 4 contact ribbon did seem to be 'seperating' a little from being what appeared to be 2 layers of other material. seems the issue was that the glue that held all 3 layers weakened over time and allowed the touchscreen circuits to not make full contact anymore. I put in a some material between the circuit board and the 3 layeres to compress the 3 layers together and give it pressure and the unit worked perfectly after that. THANKS!

well, I just had a second 3000 take a dump on me... tried the fix and the screen still won't calibrate. Too make my situation even more frustrating, I have another 3000 that will calibrate but the screen is black with a line down the middle. So I have one that won't calibrate and another that calibrates but is unusable... I should be getting my hands on a RC9500 in the very near future but this is such a headache!

I was fixing a TSU3500 today and noted something. Philips DO know a lot about the touchscreen problem and should have make a recall. In the 3500 there is a cut in the plastic of the LCD frame, this opening alow the ribon of the touch not to fold completly (to avoid loss of contact with the glass). By the way I had made this mod in a lot of 3000 I fixed, exactly just like philips did in the 3500. Olny difference is that the 3500 has no light sensor so there is more space for the ribon. In the 300 the acrilic condutive of light has to be cut too to make space for the ribon. Also philips gluded the ribon in the board of the latest 3500, so it´s hard to change the touchscreen. A foam was also puted to hold the ribon in place. Note that I opened some 3500 before and this adaptation where not there, proplably Philips readed this post and made the changes to avoid the problem in the latest 3500s. The hard buttons has now a soft fell in the3500s. I don´t like it. Thas due to a mod in the contact layer tha now has a new layer of plastic over the contacts. Don´t know why they changed that a down side in my opinion.

I have a TSU3000, purchased and installed the iPAQ 1945 digitizer (I have many years soldering) however the touch screen still doesn't work. I am thinking that I am just going to sell the unit including the base station (DS3000/01) with it. Feel free to contact me if you would like to purchase the whole setup would like to get 100$ for the setup... [email protected]

I just installed the IPAQ 1945 touchscreen today. It works but you have to calibrate a little different. You have to actually click more on the outside arrow in each corner to get it to work. It took a few times but it did work. I also tried dragging the stylus from the corner diagonally in towards the dot to see where it was accepting the signal. The backlight is out on this unit though. Through reading another post I have confirmed that the D381B EL driver chip is not outputting the voltage to drive the backlight. I have contacted the company about the replacement component. I will post if all goes well. If any one is still having the touchscreen problem I recommend the IPAQ replacement, It is just slightly smaller than the original but you can not tell once it is back together. If anyone is interested I am willing to offer a service to replace the touchscreen and\or the backlight driver chip once I confirm that all is well. I won't actually change the backlight (EL Panel) but the chip that drives it which may be the problem with most units. If anyone thinks they might be interested let me know. The touchscreens are available on Ebay.

The backlight driver replacement was a success. I am willing to make this repair and I'll be posting a repair thread in the Marketplace forum if any one is interested.

Hello,
I have something that is really strange happening with my Pronto TSU3000.
My screen has locked up. The hard buttons all seem to work, but when ever I touch the screen, it acts like it is frozen.
There is one exception I should add. If I push the touch screen at the top where it indentifies the source the screen represents, the screen shuffles in order through the devices. (I believe this button is called the device overview button) Again, none of the buttons on the screen function when I touch the screen except the button at the top of the touch screen.
I know very little about this remote. I have a friend help me with it when it when I add a new device, but I am trying to do more for my self.
Sometimes I threaten to get something a little more user friendly, but normally it works with out issue.
I have tried the reset button and unplugging the battery for about 30 seconds. Neither has helped.
Has anyone seen this before.
Has anyone ever experienced this with the pronto remote?
Any help/advice would be greatly appreciated!!
Thanks in advance!!!
Craig

Now, alas, after four long useful years, my RU950 has done the same thing...worked faultlessly until I shipped it to Australia! Dang...suppose its now time to convince Mrs trustworthy to get a 9600...!

My TSU3000 LCD suddenly stopped working for no apparent reason.
I read all the LCD failure posts I could find and tried the "Pin Trick". I had the remote working and back together in 10-15 minutes.
Thank you to all for your contributions.

Hi, Sorry but I'm french customer of a Marantz RC5400 and I've got the touchscreen problem and calibration fail when I try to update the firmware... I try to fix the problem : clean the contacts I removed the cover and i find this :   the touch screen is welded to the printed circuit in two points !! (red circles) The TSU3000 is also welded ?? I don't undertand the meaning of : "pry the green frame off the touchscreen" ? I can see the four contact points on the flexible plastic but i'm not able to clean them neither the metal strips at the top and bottom of the screen So What can I do ? Someone can help me ? thanks

The contacts people are talking about are indeed the points where the ribon cable of the touchscreen touchs the glass panel. The problem in your remote is that the ribon showed in your first picture, loses their contact at the point that it touch the glass. The ribon is gluded there and after some time this contact get lost. The ribon is a 4 way flat and touch the glass in four points. You can try perfurate the ribon in each contact where it touch the glass and see if the contact is restored. Sometimes just puting some pressure on it solved the problem. Some guys used the expression "to clean" the contacts but they are only making pressure on them, since the real contact is under the ribon, betwen the ribon and the glass. Perfurate the ribon on the 4 contact points make the conductor cupper bends and sometimes it makes the contact touch the glass again.
