Will not power on. Please Help!!

I have a Mitsubishi WS-55511 that worked great last night, but went to turn on today and no power from remote or button. Pressed reset and green light flashed but still no power. Checked all fuses and all ok. Any suggestions. I have seen this problem on before but no solutions yet. Called service but not available till after holidays. Thanks in advance.

Re: Will not power on. Please Help!!

I took my control panel off the front of my WS-55511 and resoldered the power switch then I replaced the panel and the Thing fired right up. Thanks for the fix options you gave me. I kind of felt it was'nt those Caps that they talk about so much, Because when my TV Quit Idid'nt have any Blinking Green lights. The TV was just Dead. Thanks Rick

I too had a similar problem. One day the remote would not work. Only the power button on the control panel worked. I disconnected the control panel and now the remote works fine.

Error code 12 means normal operation. On these models we have found that a switch is sticking on the control panel not allowing the set to turn on. Disconnect the control panel. You will be able to use the remote on it. To find the plugs for the control panel: Remove the speaker grill and front panel, then follow the wire to the connection. Remember to unplug the set before putting your hands inside of it. Tell me how it went. Lead Tech

See my reply to your last posting---The set needs The Stk-393-110 and whichever of the two pico fuses is blown replaced--I have instructions AND photos of what the fuses look like.
