My B60 would not turn on this morning. Worked fine last night. Is there a fuse in it ? Thank you.

It sounds like your power is off. all should be fine when it is restored.

It could be your mainboard. How long did you have the TV?

Check the Ac power cord,Fuses or the power supply module.

It may be a fuse. But something else may have blown the fuse. I would check the circuity of the power supply.

Flashing is either an error code or the set trying to boot up--some of the Mitsubishi sets if power removed will blink for a minute and then stop--then the set can be turned on.

a model number?

You have a blown fuse on the main board which can be replaced with a soldering iron and a new glass fuse which you can get from Radio Shack

if the air comes on for a short time and then turns off for 15-30 minutes, the overload protection inside the compressor is shutting down to protect the compressor. this can be caused by blocked supply or return vents, improper charge, bad valves in the compressor, and a multitude of other things. the problem will have to be corrected first.

If there is no power at all, then the problem is likely the power supply unit.
The PSU must be tested, then eventually replaced.

check there is a problem with SMPS and fuse/power socket problem thank u

Sounds like you have a fuse out on the engine control board (PCB) or it needs to be replaced. If you have a meter, turn the printer off and Ohm the fuses with a meter. If they Ohm, the Engine Control board (PCB) needs to be replaced. If they don't, change the fuse.
