The set took a jolt by my dog and the power went out. When I turn it on now the green light is on for a few seconds and then off. I have the service manual and the error code is 12, meaning nothing is found wrong.
I have read some of the other issues and just wonder if anyone can get me close. i can read the schematics and do the work. Just need a jump.
The Mitsubishi WS-55809 Problems and Mitsubishi ws 55809 green light problem threads have the info you need.
You can find all WS-55809 threads on this site by doing a search for WS-55809. Other model numbers sets that share the same chassis' info would also apply.
The dog is probably innocent.
