SOURCE: lg lcd can a bad tcon board kill all power

Yes , it can be a short on the board that will ask the SMPS unit to protect the power so as to switch off. So even with a multi-meter check you will be able to trace the short on the board, the drivers or any capacitor that is cutting off the power which must solve the issue.

It could be a bad T-con, but it could also be a faulty LVDS (cable that connects the t-con to the main board), or you can have a main board fault. It sounds like your panel isn't getting power. The T-con board should be located top center on the backside of the set. It should be housed under a metal cover. BEWARE, some panel have the T-Con built into the LCD panel. If this is the case, you will have to replace the entire panel if the t-con is bad. Simply go to www.shopjimmy.com, and type in you actual TV model # in the search box. This will bring up all the parts available for your model. The results will also bring up pictures of the parts so you can see exactly what they look like.

SOURCE: How do I know which part to replace in my LCD TV...is it the backlight or t-con or main board?

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

My tv model# 37lg50-ua. I have a dim picture black and gray


The TCON board or the LCD panel is faulty. You have to replace the TCON board to confirm. In some models TCON boards are integrated to the LCD panel if so you have to go for a new LCD panel.

I have a 55" Seiki flat screen t.v. and after the movers moved it from my old home to my sisters house all of a sudden there is a vertical line that will not go away


It is definitely loose connection of ribbon cables connected to the TCON board.

Half of my screen goes out from time to time. how do i fix that.


This is likely a problem with your TCON circuit board inside the back of the tv.

The TCon board usually has 2 very thin ribbon like cables running from connectors on the board to the actual LCD screen panel. Each ribbon controls one half of the screen. If you are lucky, it's possible one of the ribbons came loose or is not making proper electrical contact with the connector on the TCON board.

If your tv is out of warranty and you are comfortable working safely with electronics then you may be able to repair this yourself with a few hours of screwdriver work. The ribbons may just need to be reseated in the little flip up connectors, or you may have to clean the copper at the tips of the ribbons gently with a pencil eraser to remove any oxidation.

If you are unlucky enough to have a bad TCON board or are not comfortable disassembling your tv yourself then you can bring it in to the shop and they can probably repair it for less than $150.

Good luck and please post back if this helps and with how you make out.
