Blue and green picture on TV?

Answer 1

If you have something other than a TV with a standard cathode ray picture tube, skip to near the end and the part about calling a repair shop. Plasma and LCD sets usually don't fail like that. Yes, they can fail electronically like any of the older TVs, but it takes a tech to sort it out. It isn't like changing an alternator in a truck. If your TV has a blue and green picture (with red missing), the red gun in the picture tube (CRT) has a problem. It could be in the CRT itself, or it could be in the support circuitry (the red drive). Though it is possible that the CRT has a problem (and the picture tube isn't really "repairable" like a fault on the board may be), the problem is more likely in the red drive itself. Any way you cut it, if may be a touch expensive to fix it. Call a shop or two and ask about their estimate policy. (Have your set's model and serial number handy, and a chassis number if it is on the manufacturer's label on the set. Do your homework before you call.) Describe your problem and see what carry in or home service costs. The shops take calls like this all the time. It's their job, and they welcome the calls. You have lost your red gun (because the CRT failed or the red drive failed). See what they say. There is probably little to nothing you can do to fix it yourself. Repairing a drive circuit in a television isn't like rewiring a lamp. Smaller shops may work a deal with you if you ask. Do you have anything to trade for the service or to couple with cash for a repair? These can be heartbreakers at times. Good luck sorting this one out.
