Replacement screen is only option. You will likely have to call Philips. The part # for the screen is LPH7123 in case you were wondering. You might search on this part number for last 4 years in this forum or something like +replace +7000 +screen. (7500 uses same screen as 7000).

Lyndel,

When the screen goes to all white the problem is the mainboard not the LCD. Have one here like this, extracted the screen an put it in another 7000 and it was OK.

So white screen is problably a chipset malfunction.

Is there a place where I can get the mainboard for the TSU7500?

Philips. If you find somewhere else please let me know.

What we need is to find out witch component dameged and resulted in the white screen problem, maybe it could be replaced in the mainboard.

Yes I agree with user: ossocao
I have a remote that is very similar.
Yes it is in the component not the screen as I put a new screen on and it was the same. This one is not all white but very close. It seems what ever controls the contrast of the LCD is having issues. I changed the brightness in the cfg. and it
made it a little bit better but not near good enough.
I contacted Philips and the tech support was no help at all.
I am a Tech Support Supervisor and will not bash other support, but it is dissapointing to get little help.
If I figure out which component it the issue I will post it for all else to repair.

well, I posted on another topic, but this is very clearly the problem I have... Too bad it isn't the screen, I ironically have another screen from a ipaq that is the same model that I was about to ebay anyway... I don't really want to pay the repair guys $250 for this. I should have learned my lesson with the TSU3000 that I replaced becuase it had a bad digitizer (as they all do). I am now officially done with Philips!

My 7500 all of a sudden went completely blank white. It's been stored on a table in an office environment and been treated well. It looked perfect a couple of days before so it sounds like it's the mainboard? A number of months later, how have the results of people's repair been? What did it run to get it fixed?

My 7500 is dead too. Servicewidetech wanted $220.00 to replace the "Control Board." See my post on "Want an Out-of-Warranty Repair Facility."

ServiceWideTech seems to be the "ONLY" authorized repair facility and consequently in my opinion they take advantage of it.

They refuse to send any parts like another case or one of the screens, or even a new button assembly. They want to make sure you pay thier labor rate and be without your unit, when in reality many people are completely competent to replace things since it also appears they don't even do board level repairs, instead they just swap out the board.

My TSU7500 does this occasionally. When it happens I found I can fix it by pulling the battery, then press and hold the reset button and then reconnect the battery. If it doesn't reboot then with the battery in I hold the reset button for 30 seconds. When it reboots it's good for another 6 months or so. It feels more like a memory corruption error than a hardware problem to me.

Didn't work for me either - you must have had a main board that was "hanging on the edge"

By swapping parts, I also confirmed it is the main board, not the LCD. I suggest buying a used TSU7000 or TSU7500 on Ebay. If you can find one cheap with a cracked screen, you can swap the screens or main board fairly easily. A Youtube video shows how to open the case on a TSU6000 and there is a tutorial on Remote Central that shows how to replace the screen on the TSU7000/7500.
