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.

In almost all cases where the set is taking a long time to turn on and then turning off it will be the Power Supply board that will have bulging capacitors, usually three to five. Look on the upper right side of the Power Supply and look for any blown caps. You can replace these caps and you will be fine. Now the other cause can be the Power Switch is shorting out. You can disconnect the the Power Switch but not the IR sensor and then turn ON the set with your TV remote and see if this stops the problem. If you are not skilled in component level repair on the Power Supply board then buy a new Power Supply board and install it.

You can't see if a cap is good or bad jus looking at them they have to be measured>They loose their capacitance because they dry overtime.
I do sugest that you replace you power supply module or replace all caps.Possibily you may have a broken line in the PCB

There are several.
You should be identifying the four large components

- LED inverter driver board

99% the capacitors you are looking to identify for a power related issue on the power board.

Why isnt my samsung tv powering on?


usually with samsung tv's they use 10 volt capacitors on a 12 volt circuit board , most definatly one of the capacitors has bulged or popped on the power board if you do not know what a bulging capacitor looks like please google a pic of it then take the back of your tv and check the power board for bad capacitors

Samsung blown capacitors


Hello Chuck,

Before you replace the capacitors on the power supply board you need to check with Samsung. Your TV model falls under the class action lawsuit settlement and Samsung has agree to repair any TVs with faulty capacitors on the power supply board that were affected. You can get full details on the settlement here:

http://www.ccl-la.com/blog/index.php/samsung-has-reached-a-settlement-in-class-action-lawsuit-over-faulty-tv-power-supplies/

This settlement covers any listed unit for 18months starting Mar 2 2012.

14 month old samsung 32in 530 series lcd tv will turn on fine, then after a few minutes start turning on and off repeatedly for ever...until i pull the power. What do i do, call samsung?


its possibly dry joints on the power supply-the heat generated causes the solder to crack,and when warm creates a "crater" on the affected joint and expands with heat,and loses contact until cool.(retraction).should be easy if you are handy with a soldering iron!.failing that,take it to a repair shop as its out of warranty,and samsung will not want to know! (unless you got extended warranty,of course!)
good luck,steve

I have a Samsung LN40A450 LCD TV that is only a year and a half old. I am getting no power to the tv only a consistent blinking red light and a audible clicking/beeping noise. What needs to be replaced?




I will explain how to:


  • Open the case of the LCD
basically in all LCD monitors have two circuit boards (power supply board and system board)
  • After you open you will see the two boards are

  • You see a board that has a socket for the power source. wrote that the board we're looking for (power supply board)
  • Remove all cables connected to the board and take out the board. (get noted before you unplug it)
  • Now you see it components on board, we looking for capacitor.(see picture below)
46ddc22.jpg

  • Looking for damaged capacitors, physically you will see a capacitor on the top like a bloated (see picture below)
7a91ba9.jpg
  • Replace the damaged capacitor with the same value that you can see on the surface of the capacitor. (In this step you need any soldering tool)
My advice: replace capacitors with higher voltage, like 10V replace with 16V or 25V will be fine.
