Hi,
I just picked up a Sony PVM-2530 yesterday. It's an awesome monitor, but it is suffering from a little bit of picture distortion and I think the brightness needs to be internally adjusted a little bit. All four corners are bending inward a little bit, which I think is referred to as "pincushion". Anyway, I can't seem to find a service manual online for the monitor. I understand that the main PCB in the TV has a bunch of adjustment pots on it, but are they labeled? I also noticed a few labeled holes in the back that seem to be able to be adjusted with some sort of special tool. They are "R Bkg", "B bkg" and "Sub BRT". I think the first two are for red and blue bias, but not sure what sub brt is.
Anyway, if anyone can either link me to a manual that covers this stuff, or help me out a little bit I would much appreciate it.
Thanks!
Chris
Update:
Last night I turned on the monitor and immediately saw a flash of light through the top vents and heard a pop. Now the monitor won't come on. When I turn it on, I just hear a "click" and then nothing. I opened it up, and it was EXTREMELY dusty in there. Like there is a layer of dust on everything. What are some possibilities as to what went wrong? Was this probably catastrophic damage, or could it have blown a fuse? I'm just trying to get some ideas as to what to look for in there after I blow the dust off. The monitor had a nice picture (although as I said before it needed some adjustment) so I don't want to just throw it away if it's something that is fixable.
Thanks for your help,
Chris
I just junked one of these a few weeks ago that had a distorted upper right corner. I was told repeatedly and by many persons that was caused by a bad capacitor (or capacitors), not sure if this has anything to do with your unit breaking as I just got rid of it after letting it sit for so long.
No there were no picture distortions except for the geometry thing, but I found the pot inside to adjust that. I think I have a bad power supply, so I am going to try swapping it out tomorrow.
