    Thank you. Quite the easy fix too. Replaced all three, though the two outer ones were the only ones that seemed damaged. Thanks again.

470uf 35v -located on the power main board this capacitor is slightly larger in diamiter than a pencil and about 3/4 of an inch long. there are three of these next to each other. the center one is usualy the bad one but for two bucks each your better off replacing all three.

No power, will not turn on


check the capacitors and replace the power components. Do not mess with if not handy with soldering electronics as mother board and capacitors may need changing. Depending on MB , Tv repair maybe 75-150 dollars .. again depending on capacitors and motherboard ..

Have a samsung LN52B750 that was on during a lightning hit. It gets power but it will not turn on. You can hear it clicking and the red led power light blinks 8 times. Help


Hello,

The problem is that there is a burnt or bad capacitor on the power supply board of the television, it is not longer responding, while it tries to respond is when you get the clicking sound, therefore it is not going to power on until the bad capacitor is replaced.

Run a check on the power supply board, you will definitely see the bad capacitor, have it replaced and the television will turn on after reassembling the television back together.

Thank you for using fixya

This is a protection circuit that prevents the tv from coming on (to stop damage of the components) ....you need to check your voltages off the power supply and make sure they all read well (EX: 24v12v5v etc). Also look for popped capacitors that would make the values lower than need be for the tv to power on properly.


Once you repair the power supply then you may need to replace other components if needed (EX: backlight inverter)!



Please rate if this helps! :D


Replacing capacitors is ALWAYS the cheaper option, but you need to have experience it, or you'll create more damage than good!

If you are certain that the capacitor is OK, there could be a different problem on the main power board or even on the sub-power board. The sub-power board should have output voltages even if the main power board is defective.
