If your able to take the back off and have experience in soldering then you can look on the CRT board on the picture tube for cold solder joints, it should be quite visible. There are 3 transistors that look identical so I would look those over closely. Those are your Red, Green and Blue Video outputs. If you choose not to and want to take it in to a service center try and find one with Free Est. Notice on your screen if you have diagonal lines, if you don't, that's a good sign. Let me know what you decide!
Sounds like the red picture tube could be shorting internally which would cause the "all red" condition. In which case you'd have to replace the red tube. Are there horizontal (slightly slanted) lines through the picture as well when this is happening and a very very bright screen? If so it's most likely the tube.
Time to contact RCA again. Either you have been unlucky enough to have a second tube fail or you have had a color driver ic fail. Either way time to contact RCA for another replacement.
sounds like the Red CRT (tube) has shorted. You can test by removing the RED crt circuit from the end of the RED tube and making sure it isnt touching anything try powering up the set. If it comes on and doesnt shut down the red tube is the problem and will need to be replaced . expensive part to replace the Red XRT will be over 300 and at least 2-3 hundred to have it installed unless you know someone who can replace it for you.
tube replaement in these units are extremely labor intensive. shadow may mean a bad focus pack or it could mean a bad tube or bad crt board. but i would suggest geting a tech to look at it
Hello, I would take it to a TV repair place, they will charge around $50 and let you know what the problem is with it. this is your cheapest way out, it you want to keep it. If you chose to take it please give me a fixya rateing. Thanks, Farren
Take off back cover--look to see if red tube is lit,if not then voltages must be measured at red CRT circuit board. One way to help diagnose is compare voltages to working tube either green or blue--------Let me know.....T.
The loss of blue could be one of 3 things. First of all if you are connected to a HD cable box or a HD sat. recvr. using component cables. Make sure the BLUE connection hasn't fallen out or is loose. The possibilities is the blue CRT (picture tube) itself or something in the blue CRT driving circuit.
