It sounds like the convergence went out. STK 394-250 and some pico fuses. Check that the error code is 2.2 before you replace any parts.

To check the error code simply hold down the menu and device buttons for 5 sec and count the flashes inbetween pauses. Goodluck.

We heard a "pop" noise


The pop noise could be a capacitor poping its top up.This is a common problem to most TV sets today. Usually located at the power supply board.Once this parts give up it usually shorts the circuit and blows a fuse.Replacements of these parts mentioned will often remedy the problem.Flashing power indicators indicate a problem.If you have the chance of counting how many the blinks are I could have told you the problems code are and the source of the problem.

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.

Red lamp light stays light


I doubt that it is the optical assy. it sounds more like a chassis problem either on the DM or the FMT board.

check out www.tv-techs.com
if it is a chassis problem it will cost about $250.00 plus shipping one way to fix the chassis
