42 inch LG Plasma TV - Lost picture


Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

Since you smell it above one side of the panel I will guess the right side (from the front). This is where the Y Sustain board is located, it has large heatsinks over the drive ic's to dissapate heat. If the ic's are bad this is more than likely the smell. This board controls the scan of the picture and drives the plasma panel. I would definatly have a technician look at the unit, these are normaly econimical to repair.
