It is possible but a voltage check of the power supply will tell if it is bad or something downstream is pulling voltage down, power light going dim means something is really loading the supply down.

My 42" Westinghouse HDMI inputs just stopped working. I thought it was the TW Explorer 4250HDC issue so I got a new one from TW. Still said no signal from HDMI. So, I shut the TV down and pulled the power cord out of the back. I waited a few seconds and reconnected the pwr cord. The TV "re-booted" so to say and now the HDMI inputs work. I think TVTEK has the right idea that it is firmware/software related. In the mean time, you might want to give that a try.

This is a backlight or inverter Problem. Based on the model you have, I am guessing the inverter is defective.

Inverter is defined as the board in the TV that supplies power for the flourescent lights inside the LCD TV that provide backlighting for the TV's Display

Your main board is faulty. I've done several of these but haven't been able to figure out which component is actually bad these yet. I've simply had to replace the board itself, and it fixes it every time. One thing you can do to get your backlights to come on (and so you know I'm not Jive'n you) Is unplug the three wire bundle that spans from power supply to main board. This will usually make the backlights fire up. I even had one that after I left it that way for a minute (with the backlight on) it suddenly started working again! But this was short lived. :-(
One time I even tried recapping the entire main to see it that would fix it. It did not. I think it might be something to do with the small chip labeled SL37HA37. It's a 16 legged bastard near the 3-wire plug I told you to pull. It's that or possibly the bigger IC near it that has a heat sink on it. The ball grid array solder joints may be faulty. Just guesses, if any smart guys out there figure this one out, be sure to tell the rest of us please!

No picture sound only


your lcd tv is most likely not getting enough reception for the visual signal, try switching your tv back to analog signal (not digital) if you can by switching off av on remote, do you get your picture back, if yes thats your problem check your aerial, aerial leads and plugs, also do you have an aerial amplifier plugged into a power point, is it turned on to aplify signal.

OK,you need 3 leads,(A/V leads),normally red white and yellow.

So yellow is for Picture (video).go from video OUT (combo) to TV video IN.

Then red and white .... Audio OUT of combo into Audio IN on TV

TV must then be set to AV1 or AV2 depending on which AV inputs you used..

LCD TV has sound but no picture.


Shine a small bright light at the screen when on and see if you can see a faint picture in the dark screen. If you can then your backlighting is not functioning due to ccfl (inverter), power supply, or back light lamps.
