If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hi,
Hisense TV's usually use PCB Boards by Vestel and not Hisense themselves, have a look at: Vestel Help If the Boards in your Hisense match this Board/Part Number format at least you'll know what to search for, replacing the power supply will not help unless the process has been incorporated into the power supply and that is not known for certain yet
Good Hunting

My TV is a LG 47LN5700-UH I had a lightning strike near the house. Afterward TV would start but not boot completely. Now it won't start at all. Cable box also got fried at the same time.


The led driver AND the T-con board are bad. If you could see a picture with the flashlight then the T-con board would be good. It is not. The led driver can be on the main board or the power supply board. You can get these parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Where is led driver located on Westinghouse DW39F1Y1


I don't have a service manual for your set but I believe the LED driver is part of the power board, did you test the voltage going to the LED panel?

The answer to my question was to replace the T-Con Board. Looking at Shop Jimmy the only board for this model is BN44-00801E Power Supply/LED Driver Board. Is the T-Con board embedded in this board?


The T-Con board is embedded in the main board and not in the power supply/LED Driver board.
The Main board part number should be BN94-09124C but I would suggest to do more research or call Samsung for more info.

How do I fix a Samsung UN32EH5300FXZA LED TV with a blank screen, but with backlights and sound working?


Sounds like 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. http://electronicshelponline.blogspot.com/ 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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board..

Samsung LED TV (UN39FH5000FXZA) has audio, but does not have backlight. I replaced the power supply/ LED board with no success, could this be caused by the main board or the t-con board?


Hi Matt,
The fault lies with the backlight LEDs. It is common with these sets. If you open the panel and replace the failed LEDs, or replace the panei.
Good luck.
