Wed, 27 May 2015 14:37:17 -0700

This tv stopped working after just 3 yrs normal use. No picture or sound, but it's getting power. Opened it up, the capacitors look perfect - no bulges, leaks, etc. now what?

LG 37LF65: Black screen, sound OK

Tue, 04 Jun 2024 15:22:28 -0700

My TV had a picture that blurred from time to time.

On the PPW-EE37FH high-voltage card, 2 capacitors had blown. I replaced them with the same ones.

Then, I had an lvds sheet on the T-con card that was coming out of its slot.

I put the LVDS cable back in place, without switching off the TV... There was a spark and since then I've had sound but a black screen.

Thinking I'd burnt out the T-con card, I bought a new one.

Unfortunately, the problem is still there.

Do you think that connecting a powered LVDS cable could affect which card?

Last question: my 2 LVDS cables are in very poor condition. It's not possible to read the exact reference, because there's aluminium paper covering the reference. I can only read: EUNSUNG-E12954. The size of this tablecloth is : 31mm x 80mm.

Can you tell me the exact reference and if you have it in stock?

Thank you very much for your help

Hello and thank you for your prompt reply.

Here are the photos of my LVDS cards and tablecloths.

On each picture, I've put some notes that might help you.

But when you look at the state of my LVDS tablecloths, I think that until they are new, I may not be able to make any progress in solving my problem.

Now I don't know how to find compatible LVDS tablecloths....

LG 37LF65: Why is the LG HD TV display black and can only see a faint image?

Fri, 11 Sep 2020 07:19:07 -0700

I am an onsite engineer trying to rectify my end user who have problems with their LG HD TV.

When the LG TV is power ON, a light flashes on the screen then goes black but it’s a dark screen and I could vaguely see a faint picture on the screen.

Any advice on how can I able to resolve this issue.

Is it caused by a backlight problem of the LG TV?

LG 37LF65: LG TV 37LC45 goes black with slight flickering on top, sound working.

Tue, 04 Sep 2018 17:10:14 -0700

Usually it will work for a while until it goes black with the said flickering on top. Sound works and the image for a random amount of time. Any tip to fix it/ broken component(s)?

The first image its the tv working normally, the second when it goes black and the third an odd angle of the back of the tv.

FYI the image got better as I played around with the tv, before there were a lot of colored stripes and the image quality was awfull.
