Re: Lg 37 lc2db

It's an LCD.

You weren't clear on the symptoms but I'm guessing all too common no sound problem from your post.

The 3.4V output on the PSU is defective (measures low) and that will cause no sound.

Re: Lg 37 lc2db

basically no sound,someone who had it before said he could even get sound out of a amp plugged in ?

Re: Lg 37 lc2db

Yes, bad 3.4V output almost certainly, very common issue.

Re: Lg 37 lc2db

tom have you a diagram or picture to highlight please.

Re: Lg 37 lc2db

No, but I know the 3.4V is on the PSU, and the PSU outputs are labelled, you need to take a few pictures so we can see the chassis layout of this TV.
