Re: Samsung UN60H6203AFXZA steady flashing backlights


ShatterMasters, I didn't see your reply. I still have the board if you're interested. I pulled all the parts from the unit before I trashed it.


I don't have the part number, but I bought them from Shop Jimmy. If you put your model number in there, it'll show you what fits....

Re: Samsung UN60H6203AFXZA steady flashing backlights



Anyone want to buy a Samsung UN60H6203AFXZA for parts? Brand new LEDs! ...

Re: Samsung UN60H6203AFXZA steady flashing backlights

Well, the LED back lights were definitely bad. Replaced them and they tested right at 112v.
But when I put it back together, I now have this.

I was hoping I just didn't attach one of the ribbon cables for the T-Con board but I rechecked and they're all good....

Re: Samsung UN60H6203AFXZA steady flashing backlights



I gotcha now. I pulled the board and the traces look good.

Tested S- and S+ again with the LEDs in place and they were the same, though jumping around a bit as the LEDs flashed.
I figured the NC had nothing going to it. My meter was showing negative voltage so something must be going on there.

Thanks for the help!

I've got another older Samsung that I think has bad caps. That's my next project....

Re: Samsung UN60H6203AFXZA steady flashing backlights





I was thinking LEDs myself, but this is a first for me so I thought I'd ask some experts.

R_J, are you saying I should check voltage between 1&2 and between 4&6? With the LEDs unplugged I assume?...

After spending unknown hours searching the web, I keep ending up here so I'm hoping someone can help me with my problem.

I did find this thread [url]https://www.badcaps.net/forum/showthread.php?t=69298[/url] but the OP didn't report back on his results.

As the title says, I have a Samsung UN60H6203AFXZA and as soon as I plug it in, the LED backlights begin to steadily flash. The TV does not power up that I can tell. I get no boot-up sequence or sound.

Power supply board is BN44-00775A. I don't see any bad caps or signs of excessive heat anywhere...

Hello. My name is Steve and I would rather repair something that see it end up in a landfill.
I'm also incredibly cheap so I don't want to spend money on something I can repair for much less.
