I was watching my Hitachi 42hdm12 and heard a pop and now the picture won't show up or sound or anything?


A pop is usually a power surge and you blew a board. If you take the tv apart, if this is it, it will be evident by the burn marks. You could have burned out the internal power supply as well.

Watching TV and all of a sudden a loud pop came from the back of the set. Doesn't turn back on after unplugging.


Hello
Check its power supply regulator board. The pop sound you heard may be due to an explosion to any electrolytic capcitors on it. If the line voltage exceeds, this fault will happen. just repalce the damaged component. It is best to replace this board as card basis.

You will find that the power supply has failed and is no longer supplying the VS voltage that the screen requires to produce a picture.

No picture but have sound


That click might have originated in 2 places: either it was the main relay disconnecting or it was the sound of a capacitor popping. Both are very severe problems - they signal that the power source of your tv has just failed.
Fixing it is a job for someone with electronics experience, if you're not one then call a repairman.

Pop sound then no picture, just sound


I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

Your TV mainboard is damaged and need to be replaced, the price should be around $80-190 and you can do it yourself.
