A loud popping noise, like a sharp "snap!", is usually caused by high voltage arcing. Somewhere in the high voltage system an insulator may be cracked or loose, such as the plastic around the flyback transformer or one of the rubber cups on a picture tube. When the high voltage arcs, it momentarily drops and the picture could go out for a split second. High voltage is dangerous in projection sets so allow a qualified tech to service it for you.

I have a panasonic pt-53wx54 picture went black with a view vertical color lines then they went and it's now just black. sound is good no picture.. what do i need to do? thanks so much

This is one of several models that had a common problem.

If set comes on with sound and you after a minute or two see a faint odd band of noise top to bottom on the screen to the right side C509 which is a .047 cap at 200 volts is bad.

Cap is seen in attached photo(location marked and cap here gone).

The cap when you locate it from the C509 number which is on top and bottom of board may have a crack or not---it is the cause of this problem.

There is a hard way and a easy way to get at it--let me know and I will explain.

There are several brown caps here and some plugs here are removed.

I would not try operation of the set in this condition too long.

Picture Stretch on Panasonic PT-53WX54

Usually this is an indication of a failing capacitor in the vertical circuit. Have those been checked? I would look for 100ufd caps in the vertical circuit. Check with the tech.

No picture, just red-blue-green lines through the middle of the screen very faint.

The PT-53WX54 is a standard projection set and does not have a bulb. It has 3 separate picture tubes. If you have lost the picture completely, not even on-screen menu, then something has stopped working in your set. It could be a video processor, vertical deflection or possibly a convergence problem. The set should be serviced by a qualified tech familiar with the Panasonic projection sets.
