When put on tv, has a Red line through the middle of screen and no picture. Sound is fine, channels change but no picture. This was a sudden thing as no warning signs occurred. Tv never flickered or did this before. Can it be fixed? Is there a lamp that can be serviced at home?

Re: No Picture On Screen and red line in middle.
The set has a vertical problem if the line you mention is from side to side ,if the line is from top to bottom the problem is in the horizontal circuit and both can be repairable,a vertical fairlure is a common problem,the vertical IC goes bad and it takes a safety resistor with him to prevent any more damage,the horizontal is rare but it happens too,if you are familiar with tv service you can change the IC but you will need a service manual to identify the part,you can get a manual overnight if you downloaded it at www.servicemanuals.net,if you are not too familiar you should seek the help of a servicer for safety reasons.Let Us know how it goes or if you need more information.

I have a LG 42PM4700-UB plasma tv that just went black. The red power .... I have a RCA 32 inch it has no sound or picture !Just a light blue ...
it sounds that have problem in the chroma board ( video board ) a small board that hooked up in the neck of the picture tube. if the color is greenish the cause is dead in red video driver transistor or open resistance. hope this can help good luck.
This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.
