Question about Samsung Televison & Video
TV went black the other day, still has sound, did the flashlight test and when I press menu on the control I can read the functions, I did not see any backlight in the back, any idea if its the T-con board or the PowerBoard ?
There is three possibilities:
1. Defective back lights LED strip.
2. Defective LED driver section integrated in the main power supply.
3. the main board.
How to check it:
1. You need a LED back lights tester to check the strips, or open the panel, use a 3.7 V DC power supply to test each LED diode separately.
2. Use a multi meter to test the out put DC voltage from the connector to the LED strip between the + & - for each section, (like 1+/1-, 2+/2- etc.) it should read 140 - 220 V DC. (need power up the TV).
3. Un-plug the cable between the main board & the power supply, power up the TV, if you get the back lights light up, the main board is bad.

SOURCE: Jimmy shop.ccom has T-con board part #T500HVD0.0 500t10-C02 at the bottom in the description it list model PLDED5030A CRk my model is PLDED5066A-E since the parts # the same will it work in my tv?
If you see an image with a flashlight the T con board and power supply board are good. The back light controller board is the culprit.

Fault at its main digital 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.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

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.
