Re: power but no picture

We have this same problem and changed out the power cord on the back that helped. It still does it from time to time and we will just unplug the power cord from the back of the tv for a couple of hours and it will start working again. It is such a pain!!

How do I fix the problem with my TV? Details are below.

Normally on the Panasonic tv this will call for a service call. The key to getting it repaired correctly is to check for a certified Samsung repair shop because most of the parts come from Samsung. Now if you want to do your own research call to 800 number for Panasonic Tv see if there are any problems with that model that the manufacturer has extended but does not post. I had one repaired that the red light on also so I understand and it went out approximately 4 3/4 years. If your in the Atlanta area use Norman electronics they have repaired hundreds on tvs for me due to my work.

Older-model Toshiba TV shuts off by itself

There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

Change input device to some other which you know works for sure. If problem persists, try changing the channel. If you notice same problem, this may need attention by a qualified service technician.

Hitachi 55" Plasma HDTV, 1 yr old, suddenly lost picture and sound, but power light still on.

It sounds like a shutdown circuit is being activated. This is normal in cases where the power supply id drawing excessive current. I would suggest that you get this looked at by a qualified professional. This is because this problem may be in the power supply and the voltages can get dangerous in this section of the TV set.

In any event if this is a power supply problem chances are the technician will just have to replace the power supply. Which should cost from 150-250 dollars.

I hope this helps
