How to Repair Samsung 40" TV no power or power cycle Bad Capacitors LN40A550

The solution is to replace 2 1000mf/25V capacitors located in the power supply as shown.

Nice video! I have exactly same issue, trying to recover a 2009 LN40A550P3FXZC found dumped on the curb. Same power board (BN044-197A) made by Hansol. Here are the locations and values for the caps that tend to be swapped out in repair kits. I've indicated below also the caps you swapped on your TV, and the one that seems to be the most obvious issue on my TV. However it seems it's best to change all of them just in case. Circuit Reference for commonly swapped out caps: CM808 - 220UF 25V CM810 - 470UF 25V (this one is bulky on my TV) CM804 - 1000UF 25V (I think you replaced this one) CM806 - 1000UF 25V (I think you replaced this one) CM809 - 1000UF 10V CM812 - 1000UF 10V Notice that the original cap at CM810 (at least on my TV) was rated for 10V (also shown that way in schematics and probably on your TV set), but replacement kits are substituting the higher 25 V version of that cap. I'll start by replacing my CM810 (which is obviously swollen and leaking) and then perhaps just do all the others just in case.

How do I remove circuit boards from a newer model samsung Here are the numbers . TV is un65ks800dfxza Version F803 by Samsung. Power supply is BN44-0088A and main board is BN9410762V. They have no visible screws connecting it to the chassi. How do I remove the whole board? There has to be some answer to this.

Check the incoming power for a shorted diode or full wave bridge rectifier on the large heat sink on the board.
