What you can do is take off the back pannel and there is a cord on the top of the board that looks like a computer board, there are many boards in the TV but the one I am talking about is twords the bottom where the video jacks plug in to the TV. Ok once you have located the pannel there is a cord on the top kinda tword the right side, it is many wires inside a black covering. What you need to do is just simply unplug it and plug it back in, do this as many times to try to get it to fix the problem.

If you have never changed the lamp this is more than likely the issue, as the tv ages the lamp looses brightness. Most lamps are rated for 3000-5000 hrs of use. Replace the lamp assembly part # UX21514 and you will notice a much brighter picture. You do not mention if the tv plays the right colors on the entire screen. These have had light engine issues.
Good luck with it
# 1 above you have covergence problems ,there is a service flash from rca to fix your fault,ask your tv shop. fault # 2 above turn off the color and adjust your screen settings for a grey picture,set brightness and contrast to middle settings. # 3 fault read #1 cause if your auto focus will not correct you require service there is a harness connector that looses connection and causes several fualts on the 52" rca's you can repair the fault but if you miss the harness replacement you will do it again.
Have you checked for dust on the Tubes and mirror? This may cause a bad picture quality. Also power supply related problems like capacitors can cause a dark picture. Try replacing some of them in the power supply area and line stage.Also adjustments in the service mode,but for this you will need the service manual. Good Luck,JUS004
you "tooled around with the convergence board"
well this chassis has several problems
if the convergence doesnt hold replace both stks
resolder around that area per tosh tech bulletin
the bright problem is probably the hyper module
all toshs should be checked with toshiba website to see if they were part of the recalls for power supply caps
