Panasonic TH-42PX75U won't turn on

I have a 42 inch Panasonic Plasma that won't turn on. It's about 1 year and 3 months old, so it's just off warranty. A couple weeks ago I went to turn it on in the morning and it wouldn't turn on. No flashing red lights at all. The DVD player is plugged into the same power strip and works fine, so I know it wasn't a power issue on my end. I called panasonic and they had me try a few things that did not work, so I took it to a local repair shop. After two weeks of not hearing anything from the repair shop, I stopped in and he said when he plugged it in, it worked fine. So I brought it home and hooked it back up. It's worked fine for about a week. This morning, I tried turning it on and nothing. No flashing red light or anything. I unplugged it and plugged back in tonight and still nothing. I'm not sure if it's a loose connection internally, bad power supply or what? You have any suggestions on this?? I have the same tv, same problem. Will try to figure out problem. Mine is 19 mo old.

Your powerboard is damaged, and need to be replaced.

Sometimes it appear the TV is working again with no problem but it is only a matter of time for the board to get completely damaged.

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.

Our Panasonic 50" TH 42PX75U


well it sounds like something fried inside the tv. In my experience, this sounds like your y-sustain board went bad. it could be your video board also. considering todays value of the 50" panasonic plasma, it will be cheaper to replace it, unless you are willing to spend around $300 to get it fix at a shop.
good luck

Green vertical line down the screen!


Hello,

Most likely the failure of the Screen.

If you purchased the product new, and have the receipt Panasonic will repair it FOC from what I understand, at least 3 years, your TV is no where near that old yet.

If you bought it, but don't have the receipt.....
