    We have the exact same problem.We bought a PLTV-4250 LCD Protron a year ago, and all of the sudden i can only watch DVD's no cable TV. I can not even get to display the menu of that TV properly. Thinking i neede to adjust the contrast or something like that.



    Any help will be much appreciated.

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.

No Picture -- just a black screen on my vizio vx37L


Did you hear any pops before the screen went black?
You've tried completely discharging it? Disconnect everything off the TV, all cables and power.
Press and hold the power button on the TV for at least 20 seconds.
Let it sit, and in about an hour, plug just the power in (directly to the wall) and see if it comes on. There should be an indicator light, is it white or orange now? Was it a different color before?
Odds are it's a board, be it the main or a video, don't know for sure. If you can take the back of the TV off and see if there are any evident signs of damage, blown or swollen capacitors, burnt traces or resistors/diodes, etc.

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
