I've got a matched pair of Sony PVM-2030s here, and for the life of me I can't get either of them to display an RGB signal.
A little background: On the back of these things is a 25 pin connector labeled COMPUTER which will accept an RGB signal. The manual has pinouts and lots of people make adapters to hook their game consoles up. I'm currently trying to use an old Sega Dreamcast with just such an adapter. The adapter and the dreamcast came with the monitors and I saw it working when I bought them, but when I got it home I found that was no longer the case. The guy said the RGB port was dead on one and fine on the other, so I guess whatever went in the first one decided to go in the second while it was being transported.
So I've opened them up and poked around and found nothing visibly wrong. Nothing disconnected, no cracked solder joints, etc. I suspect something has gone wrong in the circuit which switches between the inputs, but I'm in a little over my head when it comes to tracking it down.
Could anyone suggest how I might figure this one out? Does anyone have a service manual for this beast?
