Samsung LED TV UA32F5000AR Flickering Issue (HELP)

[mjmarcha]

Hi to all veterans here in Badcaps.net, I'm Mark Jayson from Philippines and I have a flickering LED TV (Samsung UA32F5000AR). I had replaced the power supply board with a new one but still the flickering issue remains. I had little knowledge about troubleshooting a LED TV and also doesn't have tools to do so. What is the other possible cause of flickering? I'm hoping you could help me fix my tv.

I attached pictures of my LED TV for references.

What tools do you have? Do you have at least Digital meter?
BTW, I cannot read the P/N on the barcode sticker of that power supply board, it looks like BN44-005??

None sir, power supply board is BN44-00605B. I ordered a new one from Thailand but still, the flickering remains. Several months ago, I googled this flickering issue and found a forum that has a member with same issue and same unit, he said that his tv was able to fixed by a technician by tracing a gap in pcb track/fuse. I'm searching that forum/post in the internet now but I wasn't able to find it anymore.

So if you remove the cable between the new power supply-LED driver board combo and the main board, the BACKLIGHTS still flicker, if that is the case, the only thing left will be the backlights LEDs or bad connections on the LED strips' connectors.
BTW, just to be sure, you are talking about the backlights are flickering or the Pictures are flickering?

Done what you've said sir and it was the backlights that flicker, i'll check tomorrow morning the whole backlight part, it's just a little hard to disassemble.

Hi sir, i found one(1) dead LED backlight, is there a way to bypass this one? I can't find a replacement that can be ordered online even on ebay. I attached the pictures of dead LED.

You remove the bad LED and replace with 5 Diodes (1n4007) connected in series, you will have to scrape off the paint on the board to get to the bare copper.

Thanks for the follow-up, you should turn down the backlights level (not the brightness) down to as low as you can (and still see good pictures) in the on screen menu setup, that will help extend the life of the LEDs, do that to any TV you have and in the future.

Had a quick look, saw a few powersupply boards for like 90 bucks, that's sick for a 32 inch tv, did you take voltage measurements on the powersupply? have a look at the second video below, shows how to take voltage measurements, HEED THE HIGH VOLTAGE WARNING.
