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: 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.

Apparently this is a known problem with flat panel TVs made a few years ago due to bad capacitors in the power supply. This same problem appeared in computer mother boards at about the same time so that the capacitors went open or shorted causing problems.There is videos on You Tube that addresses this problem see: http://www.youtube.com/watch?v=ZccykxrtX9g as a starting point and look around for other repairs

Hi,

This is an indication that the inverter circuitry or still the power supply is the caused of the problem. Inverter circuitry is the one producing high voltage for the backlight. The capacitor that you've already replaced are the mainboard's filter electrolytic capacitor that's why it has sound now.

Inverter circuitry and the power supply circuitry is come in only one board, I would advice you to replaced the power supply board rather than troubleshoot it because it will cost almost the same. Here's the LINK for the power supply board. Please double check the actual part no. of your unit which is printed on the white sticker on the board itself before ordering.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Those 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.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

LCD TV SOUND BUT NO PICTURE


Faulty parts on PS board , bad press for Samsung

Because the Samsung LNS4051D would not turn on and the power LED would blink 4 times and the relay would click and this would repeat again and again. I replaced power supply board parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors, three had their tops bulged up slightly that I missed on initial visual inspection. After seeing the reports of problems with these caps on http://www.fixya.com/support/t1336881-will_not_turn_or_off , I replaced them with Radio Shack part 272-1032, 1000 uf, 35v. They are slightly bigger, but fit OK. TV is working fine now. Cost was 4 x $1.59 = $6.36 plus the time. I saved between $100 to 300 in the process of either replacing the board or getting the unit serviced.
