SOURCE: I have a Samsung 3yo LED TV and it just stopped working. No standby light. I took the back cover off to see if the power supply board had any issues but can't see anything burnt. Help!

Did you check the plug top connections or fuse?

T'Con board fault. With most modern models of Samsung LCD sets, this board is a built in part of the display panel. If it is a separate part (in case of your set); replace it. Check it out.

If it is a built in part with the display panel, there is no repair other than replacing the display panel.

Samsung tv MODEL UN40F6300AFXZA


Please un-plug the cable between the main board & the power supply board, apply AC power to the TV, if the back light come on, that means the back lights & the power supply are OK, then you need to replace the main board; if the back lights does not light up, mostly the back light LED strip(s) is bad.

Tip

TV led back-light repair


Tv using power supply unit EAY62810301.

No back-light/sound ok.

No dc voltage measured at P801 led plug.
New board did not fix.
Remove display panel.
With face up, panel will hinge up. (after removing all trim parts) Place folded towels beneath, to prevent strain on tcon ribbon.
Fold other screens up and over on top of display to keep them in right order. Including white background reflector.
Check each series led string with 2*9V batteries and series resistor, minding marked polarity.
Circuit consists of 3 strips of 7 leds all in series.
One bad led disables all .
Check each led of bad string. I used 18V and 1K ohm.
Replace strip or jumper (short) bad led. I just jumpered the bad one that was on edge of panel. (first in string).

Hisense 50k22dg should i replace led strips first or power board


I would inspect the power board for mushroomed caps and brunt traces. A edge lit led screen has two ribbon cables coming from the power supply, I would unplug one at a time to see if one side lights up. Both led strips rarely go bad at the small time. The problem is most likely in the power supply.

I have an LG 47LN522-UB LED TV that stopped working after three years and need help diagnosing a problem with it.


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.

I have purchased a power supply led board and a main board board for my Samsung Tv and that didn't help. The light flicker on then go back off


Did you replace the LED light strips? You have a bad connection on the LED light strips or one LED itself is going bad.

LG 32LN5300 LED TV that suddenly went to Black Screen no sound. Should I change out all three strips of LEDs?


This sounds more like a power supply problem than a problem with the backlighting, plus the lack of sound also would indicate something other than problems with the backlighting.
