Re: mitsubishi vs-4543

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.

Mitsubishi VS 4543, Picture go out after a few minutes

I usually find that symptom you describe is caused by cracked solder joints on the power regulators or vertical output IC. I have also seen that symptom caused by loose solder joints on the vertical windings up inside one of the yokes. If you have experience in repairing TV's then you can disassemble the set and pull the main chassis, flip it over and resolder all of the parts mounted on heat sinks. If you do not have experience in repairing projection TV's then allow a qualified tech to handle it for you.
