Hello. The chirping probably indicates a shorted transistor or diode, and the burnt smell usually indicates a blown capacitor or a burnt resistor, or multiple damaged parts. I would have to see the TV to be of any further assistance. Sorry I couldn't be more helpful. Good luck.

Sounds like power supply is failing

It sound like its fly-back transformer side circuit fault. This is not a user repairable fault. Contact any service technician.

The noise is coming from one of the plasma driver boards. There are 2 inside the set. These are essentially power supplies for the plasma itself and contain many capacitors. The noise you hear is some oscillation inside a cap or two. This is an indication that one or more components have drifted from their rated value. While the set will continue to work for a while, that board should be replaced. If the board fails, 1/2 of the picture will be blank or the set will not start at all. Call around to get the cost of that board. Please note that continued use of the set WILL NOT cause any harm. This is an annoyance only at this point.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Cheers,

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.

ysus pcb that supplies voltage to the panel is faulty

sounds like it may be a software upgrade
