Question about Mitsubishi WS-55859 55" Rear Projection Television
'Power surge' isn't very descriptive; if you had a nearby lightning stike, that is far more damaging than a line voltage that has gone high momentarily.
I'd first pull the plug and let the set rest overnight in case a protective circuit was tripped and still holding.
If that doesn't help, let it sit again for a while with the plug pulled and remove the lower back panel to view the innards. Tracing visually from the power cord input, you should be able to see if it has a user-replaceable fuse. If not, then the power supply board will likely need repair or replacement.

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.
Thanks for using Fixya.
