The replacement of the power supply is quite easy. You will have to remove the base if applicable and the back cover, once you remove it; you should see the power supply.

To solve this type of problem, you need a piece of white chalk. Draw a line around the area where the set is at. Call a priest - and lay the poor thing to rest!!!! This isn't the first time Samsung has "dropped" junk onto its' customers. Their dvd players also had problems with their DSP I.C.s that would over heat and cause the video playbacks to "break up". Don't waste any more time or money on the product!!!!!

Yes based on your testing it appears that the power supply is at fault solely and you can opt to attempt a repair or replace it altogether. Unfortunately you will not be certain that the main board does not also need to be replaced until you have repaired the power supply.

For anyone else with this problem...I ended up getting a replacement transformer from ebay and swapping it out myself.

You have to remove the back panel of the TV, unplug the board from the harness going to it, unscrew the board (both via the set of screws going directly through the board and the set going through the plastic piece on the opposite side that, as far as I could tell, the board is glued to). This plastic piece (running the length of the board) has receptacles for the backlight bulbs, so be gentle getting it in and out. Don't forget the screw in the middle of the board.

De-soldering was a little tricky. My soldering skills are not great, so maybe it was me. But it certainly seemed to be a little challenging to get it all out. Having so many terminals probably didn't help (a capacitor would have been easier). Eventually though, I did get it out. Soldering in a new one was easy. Be sure to check continuity between the terminals of the new part and other parts of the board using the traces as a guide once you're done.

After that, simply re-install the board and put all hardware back in. Like I said before, be sure you re-engage the receptacles of all the backlight bulbs by pushing down at each notch on that plastic part of the board.

Hope this helps someone else...

Hi have Samsung tv(UN40H5203AFXZA) Version:TD01. It doesn't turn on just red light blinking, no sound/ pics.How can I know if it's main board or power supply board and what should I buy? Thank you


Hello Anas,
These failure could be a combination of the power supply and the main board failing.
I would suggest to replace both boards or if you are able to measure the voltages from the power supply and verify that the power supply is working, then you should only replace the main board.
Let me know if you require further assistance.

My samsung tv turns on and off repeatedly on its own. I replaced the power supply board with no luck. What should I try next?


Hi Jonathan,
Turning on and turning off is the joint function of the power supply and the main board. You have changed the power supply, so the only thing left to replace is the main board.
Good luck.

My samsung wont turn on already replace power supply cap


If it does not turn on despite power supply change, it has to be the main board responsible if you get power led on.

I have a Samsung HLN437W DLP TV I turn it on and in about a minute there is no picture or sound and you have to turn it off you have to unplug it


That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

Thanks for using fixya...

Goes off & comes back on.. now stays off Samsung model LN46A540P2


This could be 2 things, a main board or a power supply. I have replaced many main control boards on samsungs and it solved the problem. But sometimes it could be the power supply. You will need to test the voltages on the power supply to rule out the power supply being bad.

Remove the power supply cable to Y Main board, check Vs on power supply board when you turn on tv.
1. If you have normal Vs, replace the Y Main board. If still not work, replace the Logic board.
2. If you don't have normal Vs when you try to turn on your tv, just replace the Power Supply board.
