Replacing the capacitors would be a good start. Replace all the ones with the same capacitance and voltage rating even if they do not look bulge.
Let me know if you require further assistance.

SOURCE: how hard it is to replace by yourself main board Samsung LN-T4065

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

To solve this type of problem, you need a piece of white chalk. Draw a line around the area where the set is at. Call a priest - and lay the poor thing to rest!!!! This isn't the first time Samsung has "dropped" junk onto its' customers. Their dvd players also had problems with their DSP I.C.s that would over heat and cause the video playbacks to "break up". Don't waste any more time or money on the product!!!!!

Yes based on your testing it appears that the power supply is at fault solely and you can opt to attempt a repair or replace it altogether. Unfortunately you will not be certain that the main board does not also need to be replaced until you have repaired the power supply.

Question is about a TV. What would cause ALL of the backlighting to strobe or flash.


it's likely the voltage controller for the LED's I cant imagine a manufacturer using multiple circuits to operate such a simple circuit as the LED's. So yes, it's very likely that they are all connected to the same circuit.

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.

What's my next step in diagnosing my Vizio LCD TV picture issue?


Hi Tim,
If all the boards you replaced were good and working, the only thing remains is the panel if the backlights are on. Please see that the LVDS cable is carrying voltage to the Tcon board.
Good luck.

I replaced the t con board and the main board in my Samsung led tv and I still do not have a picture


Hi Tony,
If the backlight is there and still there is no picture, what is left is the main board. But before that please see that the Tcon board is receiving necessary voltage from the main board. Please also check the power supply board for producing all the necessary voltages.
Good Luck.

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.

Hi, i have replaced the faulty power supply but now the leds don't do anything anymore. The screen is active but stays black. The backlights are on. When i plug the tv into the mains i also can hear...


If the T-CON board is dead,you will see black screen (no picture) but you will see slight glow due the backlights is still on. Check the fuse and voltage on the T-CON board, dead main board will not be sending the voltage to the T-CON board.

But you are saying taht you cannot get any button on the TV to work, that will point the problem to be in the main board.

You will need service manual to really go in-depth troubleshooting.
