Sounds like your convergence board went out. This board aligns the Blue image to impose over the Green image and also the Red to again impose over the Green. This will take a TV Technician to replace and to fine tune your TV's image.

One yellow, one pink, and one blue spots appeared on my tv screen.


The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.

That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.

Not fixable.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

How can i repair the speakers? how can i remove the panel in front?


  • Turn on the TV set, bring up the convergence menu and make sure the three colors--red, green and blue--converge and overlap at the cross in the center of the screen. This is needed to help converge the TV later. Turn off and unplug the TV.

    Remove the front screen by popping off the bezel and pulling the three combined screens out. Place wide cellophane tape around the frame to prevent the three screens from separating. Lay the screen someplace where it won't be bent or scratched.

    Remove the circuit board from the bottom of the CRT neck. It may be held in place by one screw or glued in place with silicon. Pull it out without twisting it.

    Blank screen, no sound


    If ti blinks three times, then it may be an issue with the flyback transformer. It's called "three strikes"...it tries three times to come on, and after that enters a safety shutdown mode to protect the TV. Might need to have a professional shop take a look at it.

    I just saw your post, that is a permanat burn on the screen and there is suppose to be protection circuits inside this TV set to prevent this from happening.
