I just acquired a Sony Trinitron Multisync 200ES. It is in fantastic cosmetic shape, but when I brought it home and plugged it in, the issues started. Here's the behavior:
- I can turn it on and it shows a great picture (very bright)
- It stays on for 5 to 10 seconds and then turns itself off and the light by the power button begins to slowly flash orange (no blink code, just a constant slow flash)
- I've ruled out a resolution/refresh rate problem as it happens in DOS, the BIOS, Windows Safe Mode, etc.
- When it IS on, the brightness controls only make a TINY difference when all the way up, vs all the way down
- Contrast seems to make no difference
- Changing geometry works as expected
- Changing vertical size works as expected
- Changing horizontal size HAS NO EFFECT
- Changing horizontal position works as expected
If anyone has any tips, please let me know. I have limited experience working on monitors/high-voltage kit, but I'm willing to try. I know my way around a PCB, diagnosing logic issues, checking voltage, know my way around a soldering iron, etc.
Thank you!
