I need help with a very particular sync problem I'm having. I repaired a Sun Monitor with a Sony Trinitron tube which doesn't have a service manual, which makes things difficult.
The problem I have is that it loses horizontal sync both in the post and in most games (it's a Retro PC). It only looks good in Windows and running Quake 2 (800x600)...I tried differents frames rates (60-70-75 on windows...works fine) but half life, windows safe mode , and other similars test games the Horizontal lose sync. I've already tried changing capacitors on the sync board and I also changed a regulator.
The 3w13 Cable and adapter to VGA works fine too.
The monitor was working fine last year and now it loses synchronization in standard resolutions as I already said in Bios, Safe mode windows and Games except Quake 2.. (Quake1 lose sync too).
Has anyone ever seen something like this? Any help would be appreciated.
