I have a 50" plasma, model # R5012 that will not turn on now. It worked fine last night, but nothing today. I checked for power and it is getting power. It is only 3 years old. What's up with that. I have lost my manual, which would make no difference anyway. Is there a fuse or something I should look for?

Hi

It is always recommended not to open your tv as it has high voltages even when its switched off.However if you want to locate the fuse you need to open up the back cover of the tv set and check the fuse that is close to where the power cord comes into the tv set, check that fuse is good or not.


Please check this manual if you still want to get it done yourself.

Usually in Plasma sets the first thing that has been going out in them is called the Y-sustain main. This is a rather large module on the left side of the set ( from the rear ) . It is a rather easy part to replace, however, technically that's not the end of it. You must re-check your Vs and Va supply voltages that are derived from the power supply. Then check your Vset-up and Vset-down waveforms with a scope. All these procedures are necessary for longevity of the module. Sometimes they have been known to wipe out the Y-drive boards also. I wish I could give you better news but I can only give you the truth, I have repaired so many with the same symptoms you have, regardless of the make- they all fail sooner or later so don't feel bad or un-lucky. Your best bet is to have a reputable service co. diagnose it. Depending on the make and parts suppliers the cost can run $250-400.
