SOURCE: Initially No Picture when Turned on but sound normal and 5 minutes later Picture is all RED and then Picture becomes NORMAL (all normal colors)

theres a high voltage block that all three of the anode leads attach to and sometimes a small crack happens across this block and will not let some or all of the crt's get the high voltage all at once untill it heats up a bit. now if this is not your problem i would make sure that all three crt sockets are attached to there tubes all the way as maybe justy maybe there loose and will only work after ther expand a bit. Now another problem that could cause this problem to occor origially would be that someone left off a crt ground strap and the crt arched and popped and caused the problem with the High voltage block. And no I cant see a tube being bad then comming on at first UNLESS when you say the red comes on is the picture all red with small retrace lines(small white lines)in the screen with no picture except for red???? No video only a red blank screen is what i mean. If thats what its doing then yes Ive seen heater to cathode shorts on a picture tube that would cause this problem but to be sure your really gonna need to have the set looked at.. Good Luck

SOURCE: Red?Green picture

If you are connected to a HD cable box or sat. rcvr. using component cables, I would then suspect a loose or bad blue connection or cable. If you have Comcast and have their supplied flat component cable this is a common issue.

SOURCE: Power light flashing/ no picture

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

The screen went blank and green light started flashing. Turned off the TV and let it cool. Turned it back on, getting sound but no picture. Red light is on, after about 15 seconds the green light blinks...


Since you say that there is sound but no picture, the first thing I would check would be the status of the lamp. I believe that the lamp has been shattered or the filament is blown. Please verify this and let me know

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
