Hi and thanks in advance. My tv has a very faint picture. If I turn off all lights and position myself correctly, I can strain and see what's on. I notice the picture is either lightening up, slightly, as time goes on, or my eyes are adjusting. However, still very, very faint. I had a fellow come out and charge me $189 to "clean" the tv, well his remedy did not solve the tv's problem, he said he'd be right back, that was,....oh,.....about October, a month and a half ago. Guess he got sidetracked. Can a tech out there offer assistance?

It is likely that the CRT's (picture tubes or bulbs) are weak. It is a major job to change and all three should be changed to make the picture like new. However, it is not costwise to repair this old of a TV even if you can get the tubes. I estimate the cost of each tube is at least $200 each. I would call Pioneer and give them your model number and see if they are available. Only a trained technician should change the tubes because it requires a lot of time and setting up of the tubes and other things.
The problem you are describing is known as a pincushoin problem. I'm a bit surprized that you only see it on the 1080i signal though. I've inquired at my Pioneer contact about this and will update this soon.
I wouldn't trust anything this repairman said reason well for one thing how could he (or anyone) tell everything else is "in perfect condition" when he couldn't "see" anything to tell what it looked like. He might be right about the power supply being bad But it could also be the high voltage "power supply" could have a short and that would cause the symptions you describe But if you want to try the power supply your self you can call Pioneer and give them the model number and they should be able to get the information you need. tvkirk
You may need the power supply board resoldered as I had the same problem. The guy listed below can do it for you as I shipped mine from Illinois to him in California... Piece of cake getting the board out of the back and it's not too fraigile... Just pack in bubble wrap and it will be fine. My TV is now working great.
BUT DON'T DELAY AS SOONER LATER TV WILL NOT RESTART..
You didn't mention if this problem suddenly happened or has been getting dimmer over time. If it's the latter, it could be a heavy buildup of dust/soot/smoke (depending if there are smokers in the house or a wood stove, etc) or the picture tubes going bad. If the set is over 9 years old, I'd replace it with a HDTV set and not look back. If the problem occurred suddendly, then a resistor or some other component may have gone out and it again would not likely be a cheap or easy repair.
