Check D1SS16, a diode in secondary supply near the transformer. It's probably short circuit. Replace it with an SF-26, 400V, 2A rectifier diode, or equivalent.

SOURCE: CM 7000 will not boot up

On all units that I repair, I replace all nine of the power supply board capacitors regardless of the voltages. There are poor quality capacitors and are going to fail at some time in the future.
The logic board caps are the same through hole type as the power supply. Yes there are many surface mount capacitors but none of these have need to be replaced. Replacing the logic board caps are very difficult because of the inner plane layer that acts like a giant heat sink. I use a desoldering station that has a suction pump and set the temperature to 850 degrees F. First I unsolder the square pad lead as this one is easy. The other lead requires more time, I hold the iron on until I can move the capacitor lead and turn on the suction as I pull the part out of the hole. Even with this process the holes do not always come clean and require additional work. Without the desoldering station it is very difficult and I would not recommend attempting it.

I have a faulty Samsung LCD TV and i would like help identifying the part of the TV that needs to be replaced.

like back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Sound no pic, replaced power supply still same problem

In most model Samsung LCD TVs, the T'Con board will be an integrated part of the display panel; and will be built in. If this is the case, it can't be replaced. Only panel replacement can be done. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

I have a samsung lcd TV with a power board bn44-00264a. One day the TV just quit working even the red indicating lite does not work. I opened it and the 3.15a fuse, replaced it and blew again. Help!

Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

TV won't turn on. Red standby light blinks

Samsung told me this was a common problem and I would have to have it serviced by an authorized repair facility.
My problem ended up being the internal power supply, but they also told me the main boards burn up.
