Re: lg32lc46
For us to help we will need good clear pictures of the whole backside of the TV showing all the boards, and the straight shot pictures of the whole top and bottom side of the power supply board so we can read the printed texts on the board.
It is hard to do long distant troubleshooting without seeing what we are dealing with.
What is the history of the TV? Any works were done to the TV before?
The more details we get the better chance of finding the cause of the problem.Never stop learning

Hi all,
I’m trying to recover a Samsung UE55HU8500L (curved UHD, 4K model from 2014) after replacing the panel. The new panel is a 55A1UU8EH, which produces excellent image quality — very close to the original.
However, since the swap, the TV enters a boot loop (Samsung logo → restart) unless I enter the service menu and perform a reset.
The service mode had been previously modified — possibly by a technician or during the panel swap — and I suspect some key settings are mismatched for the European (Greece) market.

Hello,
So I was referred here when I made this poste over on AVForums: https://www.avsforum.com/threads/loc...lg-tv.3257234/
To summarize, this is a commercial TV and I can't get a menu of any kind. I know the overlay is working because when I change channel, adjust volume, turn on sleep timer I do see text. But I have not ever seen the user menu nor the installers menu. I've tried a bunch of remotes(more info on the AVF post) and tried every button... -
Hello everyone,
I got a 58pus7805 that shows some weird behavior.
The menu and remote work fine and the picture is looking crisp and flawless while navigating the menu.
However, when a video source is displayed the screen either goes solid green (HDMI), solid black (SAT TV) or shows some fragments on mostly green background (AVI Playback from USB).
I tried to reinstall the firmware through the menu which was rejected saying it already had the latest version.
I managed to install the latest official firmware by holding the control button while plugging... -
Hi, so i guess I´ll have to make a new topic here, as i browsed through hundreds of other threads but couldn't find a solution to my problem yet.
I got a EIZO CX270 from a friend. He said it doesn't work anymore and wont display any signal or take any OSD inputs. Well, as an aspiring photographer I couldn't say no, could I? Thought it was an easy game, replace a bad cap and have a working monitor. But nooope, it wasn't supposed to be this easy.
So let me start with the problem description. I'll try my best not to skip anything so this might get rather long.
