You will still need to use your SAMSUNG remote to switch the source inputs since I do not beleive the DIRECT-TV remote has full function of the SAMSUNG remote.

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.

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.

The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.

2- this unit has an issue with 4 capsitors on the power supply which sit side by side and are about 10 volt each replace them with standard 16v caps.

I just fixed this very same problem. The capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

Moat likely it is because your power supply is defective and it is not producing tv sufficient voltage to power the backlight. I would replace the power supply.

Sounds like either the buttons on the side of the tv or the function board is not working.

To all who are having power supply issues: Samsung is now acknowledging a problem with the faulty capacitors. I called 1 800 726-7864 and they said they would repair certain out-of-warranty TVs if the problem is related to the capacitors. I just called and they are sending a service rep out to diagnose the problem

Clicking noise and tv does not start. Most of the times it is the power supply board which is found defective. But I have found Main board also responsible for this problem. Please consult some qualified technician.

Mother board burnt means you have to replace it. But before you must see that the other board are ok.

Hi Metthew,
Most probably the TCON board in your tv is defective. Please consult some qualified service technician. Most of the time the company service centers ask you to replace the entire LCD panel, which is an expensive affair. TCON board is a small part of the panel. and its job is to distribute the picture information across the LCD screen. Good luck.
