Fujitsu PDS4207 : White screen only

[VirusCrazy]

Hi,

I've got a fujitsu PDS4207 which I repaired the power supply board. Now, it's working but the picture is always white. Only some black zones at the bottom of the screen if picture on the input is very dark.

Picture is fully white when no input plugged. OSD is displayed OK (ie good colors and ,no problems in OSD).

Do you have any idea of the fault ? Is there a service mode which make blank screen test which could explain this problem ?

Regards, Jerome
