Most likely the convergence output IC has shorted out and has overloaded the convergence power supply, which has stopped working. The computer senses that the convergence power supply is not running and shuts the set down. The convergence IC should be replaced, the power supply restored and the convergence circuits realigned by someone experienced in Mitsubishi projection sets. When I do a housecall for a set like that I charge $150, but shops in your area will vary so ask around.

Blank screen and no audio on Mitsubishi vs 4543 when ps3 is connected through rca cables. other electronics work fine.


Check and replace the main power regulator [SMPS] board to your TV. Contact any service technician, or the authorized service center for Mitsubishi. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

1,2 is no error detected---if during or before this you unplugged the set that clears the errors and you will get 1,2.

To confirm with set plugged in turn it on--when power light goes out repeat the self check.
