Most cases the power supply board goes. plasma displays run hot, so that causes the supply to go

I need some feed back on questions I posted a a couple of days ago, about Panasonic TH-42PX25, not turning on.


This could be a problem with the power board. Please have a qualified technician check or if non is available just change the power board all together. Please if you get stuck let me know.

How to reset tv


hi Tracie,
is the set making a clicking noise?
is the power light flashing on the front?
or no power light at all just dead?
if the set is just dead, just put your ear to the back vents can you hear like a very faint screaming noise and can you smell and burning in the vent?
if so it just could be capacitors on the power board.
if its clicking the that will need a service kit on the power supply board.
if the power led is flashing then you will need to count how many flashers from start to finish when you first turn set on.
hope this helps.
