Phillips 42 inch Plasma -Screen Issues!!!

Sounds like it may need to be serviced due to component failure which unchecked will get worse, it may be also worth try to reset it back to factory settings in its setup menu this should clear any software issues it may have, but I think its more possible a faulty part or parts which comes down to cost and is it worth it sadly?

Hope this helps.........

No--this is called a PDP or plasma display panel and no two (even same brand) can be interchanged.

The cost of a Panel exceeds the cost of a new set--broken screen=fatal issue.

is expensive to fix , tv need the upper buffer boars normally cost about $125 plus labor , may be about $300 to fix it

Y sus board issues

One of two issues/problems:
1) Main Power supply problem
2) High Voltage Power supply problem.
A Good TV Service Shop that works on Philips would be the first place I'd call. It will be much cheaper to bring the TV into the shop instead of having a tech come out to your location.
Possibly a $200 to 300 dollar repair.

I had the same problem and fixed with a great online tutorial. Just replace 3 capacitors available at Radioshack onthe the board. 2662, 2663, 2664 1 is a 1000uf the others are 100uf. Max Volts need to be over 25. It worked great, check http://dynamicorange.com/2008/06/25/fixing-a-plasma-tv/

2 yr old 42 inch plasma.screen goes black,sometimes only half screen,sound is on.it does it after 1 hr of viewing, theres a greenish line in the middle of the black sreen when that happens,
pls help.

the power board needs to be inspected. you need a t20 torx bit, and phillips screwdriver. do not work on unit around carpet. stay away from carpet.you need a digital multimeter as well. remove back cover, and set meter to VDC. take black probe, and stick in one of the upper holes. look at the top right of the panel for a white sticker. this gives the proper voltage readings. on the power board, located middle top (big bd) look for the vs, vset, va, vsc settings on pow bd with red probe, test each one for proper voltage if 2 or more mismatches, the power bd needs replaced. do a ebay search for bd id number located on bd or simply type dell 4201 power bd.
