Re: LG 37LC2D No Sound, and No Channels
I replaced 3037sc but no result
After this I swapped this 2 smd beside 3037sc [ 2 are the same] they going there where was a bad capacitor and now 4th red led is on but I think not bright enough.
You think it could be the problem?
Look at the picture, I should look for ic smd IRF7807Z or other numers?

Re: LG 37LC2D No Sound, and No Channels
Thank you Tom66, i just look at the forum on your Thread [url]https://www.badcaps.net/forum/showthread.php?t=20932[/url] a got the exact same problem and same caps.
It is 100% PSU? I think i have no chance to fix this one, can't find this 8pin SMD on the internet and we are not sure 100% is it this one, probably i need to buy a new PSU .
Do you mean one of those 8pin SMD?

Re: LG 37LC2D No Sound, and No Channels
Hello, I have a similar problem, no sound.
Just voltage on 3.4V is incorrect
3.4V-1.16V
Middle connector unplugged 1.16V
I had 1 bad capacitor, after replacement most of them except 3800uF ( green V mark) beside connectors, no difference
When the TV is off few hours sometime the sound is back and the led beside 'x' is lighting. After a few minutes the sound is cracking and getting off then I see this LED gets dark and off
Any help is much appreciated !...Leave a comment:

Re: DV6000 intel
You need to change chipset not reflow or reball, all nVidia chipset to 2009 are defective.Leave a comment:
