Picture faded to black, came back, faded again and had stayed black.
I've had this TV for ten years with no problems what so ever. A few months ago I noticed that the picture was blurry when I first turned on the set. It would clear up after being on for a few minutes. Then the picture began to overshadow black with a red haze. No adjustments would correct the redness. Then while watching a movie, the picture began to dim and slowly faded to black. The sound was still playing so I knew the movie was still on. After a few minutes, the picture slowly came back. It never got all the way back to normal brightness before it started to fade again to black. And it's been black ever since. I don't know where to begin. Any ideas? Is this TV worth fixing? Or should I turn it into a boat anchor? Any assistance would be greatly appreciated.

Re: picture faded to black, came back, faded again and...
It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.

I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.
i know your problem. its an inverter loose connection from CCFL to inverter output. back of your LCD inside the TV. try to remove and re-connect again. be sure no power and AC is unplugged. [email protected]
Unfortunately it's 10 years old. I can't recommend fixing it because something else may go wrong in a month or two and then you would be looking for a new one. It's too bad though because the problem is most likely not the picture tube or it could even be a loose connection but you'd still need a repair person. THEN AGAIN....
I just found this remark elsewhere on this forum from volts.
Don't beat it with a bat LOL, the problem your having is a simple solution, however this would be best left to a qualified tech to do, the Screen Voltage needs to be tweaked up just a tick, I've worked on alot of these sony's and 9 times out of ten thats what it is.
you are experiencing one or more of three things
1.the crt itself is damaged
2. the vertical ic on blue crt board is bad
3. the focus block is bad
if you hire a sony authorized technician they should be well aware of this problem.
