Samsung UN50H6350AF LED TV. No picture. I do get backlights and sound. (See pic) I tried replacing the main board and the T-con board and there was no change. Any suggestions? Try power supply board?


You have wasted enough money guessing bite the bullet and replace the TV. I have done this same thing and regret it to this day, should have just junked it.

Samsung 46" lcd tv changed t-con brd 5-mnths ago worked fine. started showing up/dwn pixel lines the went white. sound is great pic is white. what board would I chang now? mdl:ln46a530p1f


It sounds like your T-Con board went out again. You might re-seat your ribbon cables just in case you didn;t get them in good from the last repair. If that doesn't help I would say that your T-con board went out again.

I have a LG 50LN5600 LED Smart TV w/sound no/pic Have replaced the power supply board and t-con board. Main board only one left and research says that this would not be a main board prob. Any help?


If the LCD panel back light is not lit you have a bad LCD panel. If the back light stays lit when the set is turned on then you almost certainly have a bad main board since you have already replaced the power supply and T-con.

I have a Samsung tv pic does not work but have sound..model #40pfl3705D/f7. What part needs replaced...t-con board?? And if it is.. how do I know which board is t con board?


Here's how you determine if it's the T-Con board. Turn the TV on and shine a flashlight on the screen. If you can see the program you're hearing then the T-Con board is OK. The inverter board controls the back lights. This board is the problem.

Dont show no pic just a whiye screen


I assume the sound is still there.
The most common (but not always) solution to a white screen is to replace the T-Con Board. Check your T-Con board before ordering to ensure you get the correct one. It should be something like "81-01306A"

TOSHIBA 32bv500b screen stops working sound works fine


I'm having a hard time finding any parts for the set besides the power supply board. The T-Con is usually located top center on the back of the LCD panel. It will be under a metal cover. Sometimes, the t-con circuitry is built onto the main board. If this is the case with yours, you will have to order the main board. Feel free to send me a pic of the back of your set.

Got a new T-con but no luck


is your back light constantly on when you are not changing channels.if so replace the main board. can you see a menu if you hit the menu button ? that is generated by your main board..... replacing the t-con will only correct vertical lines in the pic.
