The bad capacitors in this set are usually NOT on the power supply--they are on the other (logic) board. You will find several bulging capacitors there. Replace em all....

SOURCE: No longer turns on

It's well worth replacing the capacitors, but this problem can be caused by a short on the power supply (Which is what the caps do). Most shorts that arise in power supplies are result of a shot transistor or diode and of course the electro caps. Check these while your changing the caps.
Good luck with it.

SOURCE: Samsung LN-T2632H won't turn on.

Follow these steps to figure out what problem is.
When you turn on TV, look at the back and see if the back light on. If it is on, the power supply and inverter work fine. The suspection now is main board and T-con board (the small board on the middle-top of the panel)
To find the problem from the main board or not. Look at the power supply and measure Vs on - turn on the TV, this approx 5 vlt DC needs constant once you turn on the TV. If it is drop or unstable - main board problem - replace it.
If Vs on is good - disconnect the T-con cable from the power sup. If power sup stop clicking - T-con need replacing. Hope it help.

Howdy,
Yes, it is very easy to repair. Solder iron wattage should be at least 300 w.

The PSB is the center Board (towards left) after you remove the back off the TV. Remove the shield that covers the Boards and remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Good Luck, big IRISH.

SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?

Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thaks for using FIXYA, BIG IRISH.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

The tv wont turn on


Does it show a red LED on the front panel? If so, visually inspect your caps on the power supply for bulginess. Specially the 2200uf 10v ones. Replace the ones bulging out and you should be back on business. It is a known problem with some of the Samsung power supplies.
