PSP Screen goes dim, gets bright when unit is twisted
OK, I suspect one of the boards or ribbons is damaged. The PSP starts OK, runs well, but intermittently the screen will go dark/dim. If I twist the PSP in my hand (yeah I know) it comes good for a period. I bleieve it was originally caused thorugh my kids playing with it and twisting the PSP thinking that would make it turn a corner more or something?
Is it the LCD/it's ribbons or one of the boards?
I can source most parts (Ebay) and have no probs in fitting, just need to isolate what part it is.

2 possibilities that I can think of for your camera are;
1) The ribbons for your keypad and screen are slightly out of their sockets causing the problems and just need fitting back correctly.
2) The ribbons are damaged and will need to be replaced.
The buttons on the back are all run from the same membrane and connected to the main board. The on/off and picture/zoom functions run from a different ribbon.
If the screen is dim then the back light is either set too low or as I said ubove it is either damaged or not in it's socket correctly.
Only way to know for sure is to open it up and have a look.
Same here, your light went out if you put a VERY bright light on you'll be able to see something on the screen if you plug it up to your computer, if you are getting a new one go dell its worth it becase they last and are durable.
How dim is dim? If the picture is still visible just like half as bright then your have backlight tube problem and unit LCD needs to be replaced, not worth repair price. If the picture goes out almost to a black screen where you can just bairly see a faint image then you hold the screen just right then you have a backlight inverter issue. If the problem is the inverter then you should be able to replace a few parts and get your unit back going. If you think you can open the unit up and maybe solder a few parts then I would open the case and look for bad capacitors on the power supply board. I can send you pictures of what to look for if you are interested. We also have a repair service for those units, most power issues run $15.00 plus shipping. Let me know if you need help opening the unit and checking parts.
Check your power supply. Maybe its wire is broken then intermitently making contact every now and then. Its my first suspect. Its like disconnecting and reattaching its power supply only in much faster way. Or test it with a good similar power supply if this will be the same.
If you are unable to change the contrast with the 'fn' key and the brightness controls, usually represented in the top row of keys as a sun icons, one brightens, one dims. You may have a bad brightness/contrast inverter in your display. It's a small circuit board in the display that controls the brightness. They do fail. You can find them for most models but depending on your technical ability, they can be a little tricky to change.
It could be the mother board or more likley the battery pack is starting to wear out.
I would suggest trying the playstation support website: http://uk.playstation.com/help-support/psp/
If you can't find anything there than try buying a new battery pack.
Well something more appropriate i guess would be my ongoing issue with DS's that have had screens replaced.
if you could describe something for me
as the unit will not power ,,, plug in the charger, if it is as i suspect you will get an orange light illuminate for 1 second, after it goes off the unit is unresponsive until you unplug and replug the charger.
if this describes your problem i would be most interested to hear weather you used the ORIGINAL screen or if it is a replacement screen
