There are 2 technical possibilities and if you are tech person, then understand easily.
If screen volts increased then picture would be too bright. (possibly flyback transformer replacement required)
If cathode volts of CRT becomes low, picture would be too bright. ( cathode volts supply error)
Let me know if you need further info.

Picture brightens then darkens


Trying with a DVD will rule the tuners in the set in or out and also suggest a setting in the set or a box if used is causing this issue.

Sirs: I have a new Sanyo 42" TV. We are on


Hello
If picture and sound is ok, and there is no colour, your push have sometimes made its system changed. I don't know from where you are, and to which country you belongs. Anyway I'll give you one solution.
Your Sanyo Tv may have multisystem compactable. There are mainly three systems in transmision of TV signals, called PAL [Phase Alternating Line], SECAM [Sequential colour and mamory] and NTSC [National Telivision System Committee]. Most of the europian countries have transmitters with SECAM and NTSC. I belongs to India, and here we have PAL BG system.

If the system has changed in the tv, the picture will not have chroma information, ie ,colour information, and black and white picture will be the result. You just do one thing. Just get into the Menu of your TV, according to its documantaion that you have, and go to the system menu, and make it "AUTO". This will solve your problem. Ok.

I have a problem with samsung sp 50 l7h a 50 inch dlp tv


I can see you have a Samsung TV, well the issue seems to be your ballast which doesn't have enough voltage to keep on with your lamp. This is why you keep losing the picture every certain amount of minutes. The thing with Samsung Tv's is that they have issues with the ballast and the color wheel, they tend to go bad pretty fast.
