Re: LG MU-42PZ90C

I had the same problem. If you are a bit electronically inclined, open the back, remove the large silver cover in the center. This is where the power cord plugs in. Remove the circuit board you see there, and look closely at the large capacitors. There should be a clump of three and a single one alone. They will be numbered: 2074 and 2081. If the silver caps on the tops are bulged, get a 35w soldering pencil, heat them up just enough to pull them out and replace them. Replace the 2200uf 35 volt with the same, and replace the 1200uf 25v with a 35v. Try to get them rated at 105 degree celcius. These caps are very cheap at Radio shack, or at any major electronics store. We have a frys here in Vegas, so I got everything there. My next project is to replace the caps on my graphics card. Good luck to you.

I unplugged the TV and held the buttons down and it continued to flash. I continued to hold down the two buttons and replugged it in again and it worked. TV back up and working.

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

We have a 2007 Sony Bravia 46" KDL-46VL130. There is not sound or picture. When we power it on the green light comes on blinking once and then the red light blinking once and then the green light stays on....

Does the front light stays green ? Or goes back to red ? The back-light going on/off maybe the problem, but it shoul return with a red blinking led (4 times ?) and if so it can be a power inverter problem.

LG 32LH30 screen won't power up. Red light at bottom glows hi to low, but no picture. Unplugged and waited overnight, plugged in again, still no picture.

There is a way to tell if you have a bad board, or a bad panel.

1. Make the room dark and turn on the TV. Can you see it light up? If so, does it stay lit or turn right back off?

2. If the panel lights, but you have no picture, I would suspect the T-con. Some units now have the T-con incorporated with the main board, so you will need to check.

3. If you never get any light at all, then I would suspect the power supply.

4. If you only get light for a second or two, then you have a bad panel.
