    I can replace the board if I know which one. Soldering would be a little hard but I can do it.

47LG70 - PICTURE WENT OUT. STILL HAVE SOUND. HEARD A POPPING NOISE WHEN PICTURE WENT. TV IS ONLY 1 1/2 YEARS OLD. ANY IDEAS WHAT MAY OF HAPPENED.


I have had the same problem off and on with my 47LG70 for months. When the "popping" noise happens, the blue light in the corner stays on, so I know the tv is still on (sometimes I still have sound, sometimes I don't). Sometimes the screen goes black, but other times it is blue. If I turn the tv off then on again, it might stay on for seconds, minutes or hours. It's been very frustrating.

This seemed to happen right after I got my new Comcast box, which came with an HDMI 1.3 cable. I read somewhere online that this tv might not be compatible with that cable, so I unplugged it and am using component cables again. I just did this today, so I don't know if it will work, but so far the tv has been on for 30 minutes with no problems.

I'm pretty ignorant about HDMI compared to component cables. I imagine I will not get as good a picture with the component cables, but I am willing to sacrifice quality if I can just get the darn thing to work. Mine is also only 18 months old.

Hope this helps. If it doesn't, maybe someone else out there can help us both.

LG 42 LCD no sound or picture


Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

LG 42 LCD no sound or picture


This is probably bad capacitors on the power supply board. My LG 42LB1DR has a known problem with this and I replaced the four bac capacitors myself and saved 5-6 hundered dollars that I was also told that it would cost to fix. I fixed for under 10 dollars and about 20 minutes. LG knows about it but they dont really want to admit it. My TV was only 26 months old when this happened. The four capacitors are made by Samxon and are 2200uf @ 10v. They are junk so even if you have the entire board replaced for say $200 its just going to happen again. They need to be replaced with a different brand.
