Problem with Sanwa 29E31S

Post by Flazh »

I switched my monitor from Tate to Yoko and ended up with this as the only output. This is with nothing connected to it, and with an input source it is just a bit brighter, but the same. Any clues as to what could have caused it? :(

Yep still connected. I've checked all the wires and I've got no loose connections that I can see. Any specific areas I should check with the multimeter?

Do you mean an input source? There isn't in the picture above, but with an input its basically the same thing but a bit brighter.

How would I do that? Is it a pot on the main PCB or on the actual LOPT itself??

Yeah I was just thinking, I accidentally turned my screen voltage up too high and it looked a little similar to that but brighter (video was plugged in). I can't imagine how you turned the screen voltage pot by rotating the monitor though. :/

Yeah, pretty sure, as it does the same thing even with the remote board disconnected, though it slowly reduces to a big block in the centre. But the remote board actually does still effect the image on the screen.

Just the VGA connector & the power and degauss connector. They're the only two connections to the monitor besides the remote board.

Yeah, I'm just going to disconnect and reconnect everything when I move house, and if it ain't fixed, get it over to Craig for a looksee ;)
