White lines pictures have tiny, faint white vertical lines every quarter inch

    I need more info, do the lines cover whole screen, and does it have a washed out, or brighter than normal picture that looks dull, and is the left side of screen darker than the rest of screen? I have seen the RGB capacitor cause this problem, but you will need the schematic, or know the main module to find the right capacitor to check for being good....generally it is a 10 micro farad at 250 volts...if it is good, the problem is going to be possiblely a vertical circuit problem..cap related...especially if the little white lines affect only the top half of picture, called vertical retrace lines...the other problem has to do with the high voltage and screen voltages. Good Luck...T.

You have bad capacitors and possibly a vertical IC that is going bad. And check for bad grounds in and around the IC and caps!

Vertical white line down centre of Soniq PT42SH plasma TV.

One of your "X" buffer boards is defective. In Panasonic plasma tv's they are located at the bootom of the set and connect directly to the plasma diplay panel via a thin ribbon cable. The board you want to replace will be directly in line with the discolored vertival line in the picture. The part number is on the circuit board and usualy starts with "tnp..." or "txp..."

The faint white lines at the top of the screen is the warning that the pump-up capacitor in the vertical output circuit is going bad and the output itself is about to short out. When the TV stops working, the vertical output IC has finally shorted out. Replacing the vertical output IC, the pump-up capacitor and possibly a small value resistor next to the flyback (B+ for the v-out) should bring the set back to life.
