On an LCD it refers to the driver ICs on the sides of the panel, as they use that technology to attach them. If there are bad connections you can get weird picture problems.

Proper fix requires equipment that cost over $20,000 so nothing you could really try except his idea."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Was watching this set, and suddenly it went dark. Picture is still visible, just very dark. Tried checking all settings, adjusting brightness to 100% no change. Reset through menus, no change.
bought used boards from ebay (power and input boards) replaced with same results, changing brightness does seem to have a slight affect.. but not to normal visibility of picture.

Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,... -
Hello Everyone,
This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.
I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area.... -
Hi all
While I have quite a decent background in electrical & electronic troubleshooting & repairs, this is my first time stripping down an LCD TV for repair.... I have inherited a 3yr old Panasonic LCD which has a picture, but it is quite dark (too dark to be watchable - but still quite easy to see; I didnt need a torch to see it).
I started by checking and trying to adjust all of the picture and backlighting levels, but that made little to no difference. I also did a factory reset.
From there I envisaged that the backlighting wasn't working, however... -
This tv is not even 3 years old. its a sony XBR-75X900H, it was like a flashbang went off suddenly, tv faded to black and no picture. backlight is on. tried to do the power cycle, factory reset. i get beeps from remote if i tap up/down but no picture. how can i determine if its the panel or a board? i have replaced boards before im just not sure what the issue is here. sony said nothing they can do and only suggested to find a local repair shop. please guide me here
