A neighbour brought me this HDD-DVD model LH7800 with the following
symptoms:
Playback and OSD OK at all times. Video signal (input) from both the 2
SCART sockets cracks up and screen goes black. There is good audio at
all times. And yes, I have tried different leads!

Dismantled it and removed the upper pcb, no obvious bulged caps or
damaged smd transistors.
I have moved the plugs but it does not seem to be a solder joint
problem, and besides it is common to both inputs.
Anyone seen this, or have a schematic? I have checked eserviceinfo to
no avail...
