Question about Mitsubishi WS-55859 55" Rear Projection Television
My Mitsubishi 55" rear projection flickers at the top of the screen, then blacks out after 30 minutes or less but the audio is still on. I turn it off, then turn it on and it is fine. However, it has been occurring now more frequently. What is causing this and what needs to be repaired?
The problem is in the optical block..the driver heats up and shuts to protect itself from total damage..that's why it turns fine after a reset and shuts afterward..this problem will continue until the drive complete gives up..cooling system might not working properly or the drive has an internal short circuit and need to be replaced..a professional service is suggested..
