I'm having a similar problem! I've taken it apart and see a spark around the green (middle) bulb. Does this mean the bulb is blown and needs to be replaced?

My toshiba 57 inch rear projection tv every once in awhile makes a loud pop similar to a spark noise and the screen either goes black or flickers. do you have any suggestions what is causing this??


THis could be one of the CRTs (Color Tubes) is bad or the high voltage is leaking somewhere.
Toshiba projection TVs have history of yoke problems.
My guess is one of the CRTs is arcing inside. This TV has 3 CRTs red, green and blue. Replacing a CRT is not easy or cheap to buy if you can find it. If you like this try calling a TV technician to track down the high voltage arcing. DO NOT TRY TO DO THIS BY YOURSELF.

Best of luck my friend.

TV acts like it is turning on then shuts off then repeat, repeat


When my lamp died the bulb literally exploded. That may be what you heard. Have you check the lamp? If the lamp is ok, the lamp's ballast or power supply might have blown.

that relay is supposed to engage power to the tv boards that control the screen.

No audio or video


the relay is kickking in but a failure in one of the boards is preventing the tv from powering up (protection circut ) and only qualified service centers have access to these parts
