Question about Mitsubishi VS-4544 45" TV

Open Question

Mitsubishi VS-4543 not powering up

When pushing the power button the tv clicks once on the clicks again off. If I leave it unplugged for a few mins it will occasionally come on for about 10 mins then shutdown and will not do anthing but click on - then click off. It has worked perfectly for years. I only use the set a couple of hours a month. I am pretty handy with electronics. Can you tell me what it could be or how to find out?

The TV is a VS-4543 but it is not a choice even thought there are lots of post for this set

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.

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.

The tv wont power on and the green timer light continuously blinks. I have unplugged the the tv and also hit the reset button.


...OK to begin troubleshooting this. Unplug the set and leave for 1 min then plug up and leave for 2 min push the power button and let light blink for 2 min.... now push and hold at the same time the MENU and DEVICE buton st the same time. this is the self diagnoses feature ... the lights should link then pause then blink again... this 2 digit code will help narrow it down. Also have you check the lamp yet?

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.
