After the tv is on for hours the screen goes black except for a thin colorful line in the middle of the screen. after a few minutes the picture will return and then goes out again. The next day the picture is fine for the first hour or two then the problem reoccurs.

hi When you let the line to long it will burn in!! you need to look into the VERTICAL output section. Most notably check the solder joints on the vert output IC and ESR the caps. If you don't know what any of that means, then take it to a professional. good luck

sounds like you have a vertical sweep problem. Where the fault lies cpuld be the vertical output IC the verticle b+ feed, could be the capacitors in the vertical circuit?? Your gonna need to troubleshoot thr vrtical circuit if your not a tech thin my advise is to take the set to a pro for sn est. Good Luck
SOURCE: 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.
