Question about Televison & Video
Pop noise was probably given by a capacitor blowing. Probably in the PSU board. The lamp usually does not do popping noise, it just goes off and the TV goes in standby with lamp led on.
If there is a pop and audio with no raster, then I bet there is no voltage in PSU line to ballast, or the ballast board is faulty. Ballast board is an high voltage board that supplies power to the lamp.
The repair is carried tested PSU and ballast board. Often it is possible to spot a blown capacitor in PSU at a glance. If you DIY bear in mind that the large electrolytic capacitors inside the TV can release heavy discharge even when power is not connected.
Price for the repair may range between $200 and $400, depending on what parts are gone and on what must be replaced.
It is still worth repairing, this is a monster rear projection TV that offers very good performance.
