Portable dvd the screen flickers and shuts off on its own

you need to remove main ckt, (m.board) some part need to re solder specially in hot area. (lost contact i one of the flickering problem you encountered.

windows dose not control any flickering unless the driver is being updated if thats not the case your flourecent bulb might be getting old inside the lcd!

1. Need Model # of set and the brand so I know if its a plasma, LCD, or CRT set keep me posted

Check if this occurs regardless what the source of the signal, whether it is DVD or cable or a playstation. You can also check if the Menu flickers as well. If the menu does not flicker along with the picture it could be a problem with the source, probably your with the cable box or the port where it goes to on your tv

try updating the firmware to this

turn off your PSP ,then switch on again.. when the screen are in black condition "press R button" and change the CPU speed

try it on tuner mode to seperate the fault from video to rf input,if gone the video pc board is at fault.

use another Tv.

My screen would flicker when you tilted it back and forth. Sometimes it would cut out and moving it would make it come back on. I took the battery off and opened the screen from the front(2 screws in hinge & 2 screws under rubber plugs). There is a ribbon plug inside. Mine looked kinked in one spot so I just repositioned it so the kink was in another spot. Everything worked fine after that. Hope this helps.

I had same problem. Tech's said the power was noisy. I cleaned up the power but the TV still did exactly as you describe. Problem will progressively get worse with longer bouts of flickering. I was under warrenty and sent the TV back. After 3 months I am still waiting for a repalcement.
