I have a Samsung TV model UN50H6350AFXZA which has sound but no picture. Backlights work. Replaced t-con board with new one, but not fixed. What next?


Main board. T con board is only involved with video issues. Main board goes both ways and since you already replaced the T con board that is your only alternative. U got backlite so inverter board is good.

Samsung LN46B650T1FXZA has vertical lines. What part needs to be replaces? Thanks, Nina


This might be a bad T-Con Board. This is the board that is in the middle top side of your TV. It connects to your main board (with the hdmi inputs) to the LCD Screen. Your TV has a major issue with the T-Con Board going back. The T-Con for that TV is avaialble here 55 46T03 C11 Samsung Con Board for LN46B650T1FXZA

The screen is white.power is on, simply no picture, white screen


Hi:
This could be cause by one to two areas of the unit, first the T-CON board may be bad and second the main system board has failed. The t-con is used to produce the picture on the screen it gets its data from the digital board or system control board. The screen is white because the inverter board is working to light up the lamps.

MY SAMSUNG LNT3242 PICTURE IS GIVING ME CRAZY COLOR AND LINES I CAN SEE THE TOP OF MY MOVIE OT TV CHAN NEL BUT THE REST IS CAZY


It can be the T-CON board, main board, or worst case the LCD panel itself, it will require in-depth troubleshooting and will require some board swapping to narrow down the problem, not much for DIY repair.

Either the T-CON board or the main board itself, check the connection between the main and the T-con bord first.

Samsung LNT4071 no picture after half hour of used


If you get just grey glowing screen (look at it in darkened room), then it can be the T-CON is not getting the 12v from logic board or the logic board is not sending the 4 pairs of the the LVDS (Low-Voltage differential Signal) to the T-CON board, you will need the scope to look at the LVDS. You can try coolin ght T-CON board with freeze spray used for electronics troubleshooting to see if the pictures will come back.

Samsung LNS 4692 lcd tv t-con board


The fuse is located just upper right to the connector that attaches to the main board. This is a SMD pico fuse that is rated for 3 A @ 32 V DC that protects the Vin bus. Replacing the fuse may not fix the problem as it has most probably opened because of failure of another component.
