PC Engine LT video issue

[herr-g]

Hello,

i recently got hand over a loose defective PCE LT.
I basically works (game-sound and controls) but doesn't show any picture on the LCD. The backlight works, but nothing else up there.
I already checked and re-plugged the internal flat-cable contacts but everything is tight and well-contacted.
I'm well aware of the common TE / GT video-issue which can be repaired by replacing the small cap on the outer edge of the circuit board, but i never experienced a corresponding LT counterpart.
Since there are lots of the commonly affected caps on the LT PCB and none of them can be measured without removing it, i'd really love to hear anybody who could already solve the problem by replacing only some of them.
If not i'll start replacing any possibly defective caps within the next days and post my solution if i find one...

Best regards to the PCE community,
