My samsung PN60E7000FF 3D Plasma HDTV will not turn on. It is like totally dead

SOURCE: Plasma TV

did you hear the sounds? or maybe you have defective power source in hot side..

SOURCE: Plasma TV-power light does not come on

There are a couple of possibilities here. If the set is indead dead, the most likely culprit is the "standby" transformer. If you are getting a click followed shortly thereafter by another click, then the TV is detecting a problem and shutting down to prevent further damage.

And if you get no clicks or anything at all, I would suggest you to look at the fuse and the standby transformer. The standby transformer is a small transformer that supplies 5V to the system even when off to allow remote control. You need to see if the primary side of this transformer is open or not. You should have 5V.

Goodluck,

SOURCE: Hitachi 55" Plasma HDTV, 1 yr old, suddenly lost picture and sound, but power light still on.

It sounds like a shutdown circuit is being activated. This is normal in cases where the power supply id drawing excessive current. I would suggest that you get this looked at by a qualified professional. This is because this problem may be in the power supply and the voltages can get dangerous in this section of the TV set.

In any event if this is a power supply problem chances are the technician will just have to replace the power supply. Which should cost from 150-250 dollars.

I hope this helps

I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.
