Epson Powerlite 3020e video issue

[tibimakai]

I have picked up this projector, from a service center, for $20.
I have never worked on a projector before.
Everything seems to work, except video on video inputs.
What I mean is, that none of the video inputs work.
Only one thin horizontal line works, at the top. The image in that line, seems like it is doubled side by side, like a 3D side by side image.
Sound works, there are no error lights on.
If I put a picture on a USB stick, it shows nicely on the whole screen.
So it must be something, with the video processing, that is common to all video inputs.
Any help, would be appreciated.
Projector, did not come with a remote.
I couldn't find a service manual either.

Menu shows as well.

I have started inspecting the board, but I did not see anything obviously wrong.
I have also started identifying ICs on the board.
Unfortunately, I can't find any info, about most of the ICs. Most likely, they are proprietary Epson Ics.
There is a ST FLi32626H (Single-chip enhanced LCD TV controller), Lattice LFXP2-5E-5FTN256C (available at Digikey), 2 x Epson EV0805SA, Epson EV2006XA, EPSON E07140K0B, 2 X IDT V105ADAG/ZA51331J, PANASONIC MN864773AKE (HDMI), TEXAS INSTRUMENTS TMDS261B (2 in 1 HDMI switch).
These are some quick phone pictures. In the weekend, I will take some proper ones, outside at sun light and with camera and stand.
