I have a Sony vx2100 and was using it fine with the LCD when all of a sudden the screen goes black. It works fine through the viewfinder and still has sound through the LCD but there is no picture. Does anyone know what the problem may be and if so is it something I can repair or will I have to take it in for repair? Also how much it might cost for repair would be appreciated. Thanks in advance.

Re: LCD problem--no picture? HELP!
I HATE TO WRITE THESE, BUT HERE'S THE RESEARCH I FOUND ON YOUR PROBLEM. HAVING THE LCD REPAIRED AT AN AUTHORIZED SONY REPAIR SHOP GAVE AN ESTIMATE OF $499.00, PLUS SHP & HAND. THEY CLAIM 3 DAY SERVICE ON REPAIR AND I CAN'T VOUCH FOR THE COMPANY AT ALL EXCEPT TO PASS WHAT I FOUND TO YOU. THE COMPANY IS LISTED BELOW. I WISH I HAD BETTER NEWS FOR YOU. IF I CAN HELP MORE REPLY TO:

Why did you change the main pc board? If the display doesn't work, but viewfinder does, there are usually 3 possible causes- LCD itself, LCD board or LCD cable. You should give it to Sony and let them find which one of these is bad. I work in a Sony service center.
If you are able to access the menu and see that on your screen, the go into the LCD settings to adjust the levels. If that doesn't work you may need to reset your camera to see if that fixes the problem. Look at your manual for proper instructions.
If the problem still persists then I'd send it in for repair.
the video playback is sampled off the video out and independently processed sorta like a TV signal to project on the lcd screen. horizontal lines means you lost sync circuit and needs troubleshooting. Hopefully maybe a bad connection with a ribbon cable for the ICs and components are hard to change and jammed tight. I would order a video board.
Just look for the post by 'airshod'. He has even put up a couple of links to pdf files with photos of the whole procedure. I used them and got mine fixed. Exactly the same problem as yours.
Be careful, though: Jackstar's (aka airshod) instructions leave this out, which you will discover after putting the whole camera back together (which is a pain): the ViewFinder (VF) will go dead, plus the picture in the LCD will not reverse when you reverse the LCD panel (which means that when you flip the panel to watch yourself while you video yourself, the picture will be upside-down, although you don't need to worry about it being recorded properly, of course. It's just a pain to aim the correctly when it's not showing the right way up!). Airshod had the same happen to him.
If you need further info on the VF dying after re-assembly, look at this link:
Unfortunately I won't have time to try the suggestion for a while, so I won't be of much help. I guess a camera is more useful with a broken VF and a working LCD panel, than the other way around.
Sony really ought to have addressed this issue by now. It's not reasonable to expect the camera to loose its LCD after only a year or two!
Fixed it, at least temporarily
I had the side off my trv250 examining it, especially the CCD connection. I had read the post about soldering a capacitor to pins 1 and 3 (from the left) on the bottom row. I didn't have the specific capacitor on hand, but I started touching some of the small ones I did have to those pins. I found that after I touched a 100uF, 10V cap to pins 1 and 3 the picture suddenly came back to life and stayed that way after removing the cap. I have no idea how long this will last, and I've set up the cam on a tripod in the livingroom with the LCD display facing me so I can monitor it. If you, like me, figure you have nothing else to lose, you might want to give this a try. Note: my camera was suffering from the green smeary horizontal lines problem, and wasn't completely black. I'm not sure if this makes a difference or not.
