Question about Mitsubishi WS-55411 55" Rear Projection Television

1 Answer

Mitsu WS-55411 RPTV-power going on and off..won't stay on!

TV just started having this problem a couple of days ago. Turned on TV and in a few minutes it went off by itself. After 20 seconds it came back on...and has continued to going "on and off". I disconnected power cord overnight. When I reconnected cord and turned on TV in the morning it stayed on for a couple of minutes and then started turning on and off again.

Is this a defective power module or is there something I can try before calling in repair?

Thank you.

Hello,

It is possible that the Low Voltage power module is defective, however I would first check the High Voltage power supply for bad capacitors (they tend to go bad first). In fact check both boards for bad capacitors (they will look puffy in appearance if they are really defective).

I hope this helps,

Thank you,

    In addition, have the technician check the DM board, it usually has defective capacitors.

Mitsu WS-55859---turned off & only powers up for 2 secs


2,2 is short protection.

98% chance the fuse or fuses (there are two 5 amp pico fuses) that protect the convergence circuit are blown. If you find F9AO4 OR F9AO5 on that board check them--if either is open the STK-393-110 DID IT.

Fairly short life for this chip if it was installed correctly and had heat sink compound applied to it--once in a while you get a bad one.

Mitsubishi 55411 projection tv has red band across bottom


go into the customer menu and select convergence with the original remote; if either the red or blue will not move in some direction, you have a bad convergence IC(the WS-55411 uses two STK-392-110 CONVERGENCE IC chips)

Mits 55908 Convergence problem


Good Day, John;
It sounds like the Convergence IC's have poor solder connections, by re-soldering the convergence output IC's should solve your problem. The IC's are large and mounted to large silver "heat sink" with STK 392 # on them. Good Luck, big IRISH.
