Re: LG 32LB2R flickering horizontal lines
I would say TCON if you weren't getting the noise out of the speakers. Still possible it could be some interference from the bad tcon causing it, I suppose. Can you unplug the LVDS cable at the bottom of the tcon and see if the sound persists?Comment

Re: LG 32LB2R flickering horizontal lines
Unplugged the LVDS and the screen turns on BLACK, no horizontall lines and no picture (due to the unplugged LVDS) the noise from the speakers is still present and it doesnt change whether I tunr the volume down or up.Comment

Re: LG 32LB2R flickering horizontal lines
It is a constant noise with no peaks, so what I am saying it is just noise, and no changes in tones. So the T-CON seems to be fine?
However when I press MUTE on the remote controller the noise is gone (dont know if this is rellevant)Last edited by CroTech; 01-25-2015, 11:33 AM.Comment

Re: LG 32LB2R flickering horizontal lines
I noticed there is a capacitor on the controller board (the one where the inputs go)... I did not replace it since it is a SMD capacitor, even though I managed soldering it on a few other boards. I will replace it just in case even though it is not bulged.
Any other ideas?Comment

After watching too many electronics repair videos (but not monitors) I came across a dell monitor with flickering horizontal lines. I haven't purchased it yet so don't have much info, but from the video and pic do you think there is a chance of repair or is just simple panel damage?
Seller claims; "but due to sun damage has some grey lines going through it"

Hello,
The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..
They are black on the right and gradually fade to nothing on the far left.
They start either after 5 mins or up to 2 hours after so annoying for testing.
They flicker continuously very fast! With a slight pause milli-second every second.
Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.
I tested each half by removing the first the left flex from... -
Hi guys

I got this tv from friend complaint is ghosting or horizontal lines on image.

Hi, I have this tv a LG 55UH661V that show flickering images and lines. I tried to take off one at time the right and the left ribbon cable and put the tape for ask the pin…but nothing working. Or I stop to have picture or still flickering. Someone can help me to understand what pin I have to mask? What I notice the buffering board, the flat cable becomes very hot, I don’t think it s normal, I’m talking about the orange flat cable soldering on the buffering board, both side are very hot. I give you the photo with both the ribbon cable on and a photo with the right off and with the lefts... -
Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks,
