Question about Televison & Video

T con board

I have LG 37LH4000. When it is cold only top 2 cm of screen works OK. On the other area there are vertical lines that refreshes every few minutes. When TV set gets warmer picture refreshes more often and after 20 min TV set works properly until it is swiched off and cooled down. Could it be T-CON problem?

Hi,
Basically it is problem of LCD Panel (screen) however some times T-Con board replacement fixed the issue (T-Con board is part of lcd panel but some part shop sell it separately). Main board is not related with this kind of problem.
Required T-Con board is available in ShopJimmy.com (click the link to view available boards)
If T-Con board replacement does not solve half screen vertical lines problem then LCD Panel will be replaced and it would cost approx new tv price.
Hope this info will help.
Thanks.

Sorry but you have a bad panel. Repair cost is prohibitive. The T-con was a good choice, but is the last step to the panel.

Vertical color lines half of screen on right side


probably the 2 ribbon/flex cable(s) aren't connected correctly between the T-CON board and the Scan boards that are connected to the screen/panel!
If not replace T-CON board, and if that does'nt work
the screen/panel is most likely bad!

There must be some loose contact with the t'Con board of your tV. Just look for it. Just unplug and replugh all the strip wires goes to T'Con board. This must solve the problem to your Tv. OK.

I have a 42JC2D TV. Vertical color bar lines


Hi,
It is hardware issue related to LCD Panel (screen).
Regarding fixing it, it depends if you are handy with electronics stuff repair and can replace circuit boards in tv etc then please check T-Con (lcd controller board) on top center position at rear of lcd panel, this board would be covered with metal shield. Need to take off back cover of tv to get access to T-Con board. If T-Con board does not solve lines problem of screen then LCD Panel is bad and will be replaced.
If you fee uncomfortable doing so then repairman option is better choice.
Hope this info will help you.
Thanks.
