1st board we bought on ebay is junk and we had to return it. 2nd seller we bought from sold us a good board. We found out that there is more then one version of the 100012588 one with 3 HDMI and one with 4 HDMI. Do this repair at your own risk as you can see this board stores voltage even when powered off and wires all removed. Be careful.

Isn't there a way to de-energize the circuit board so you don't get "shocked" when removing the circuit board? The reason I say this is because the capacitors store energy that's why you get shocked when touching it with the screw driver or your fingers. For example, you press the off button for about 30 to 60 seconds after you unplug the TV or something else that can de-energize the power circuit board.

you can short them out after you unhook the wires from the board with a screw driver. but you still have to remove the board to do so. so you still want to be careful at first.

Good video, man. Getting ready to buy this same board on eBay. Would much appreciate it if you would be so kind as to let us know which eBay seller(s) sent you the bum boards, so we can avoid those guys. Thanks for your time, and any reply.

I forget who sent the bum board. But he finally did admit once he got it back that he tried to use it in another tv and found out that it was bad. After I sent him photos of a working tv with another board from another ebay seller. He just tried to tell me it was my back light witch I knew was wrong as my mom has two of these tv's and we switched the board from one tv to the other and the issue followed the board and not the tv. So we knew the back light was just fine as it worked before putting the bad board in. Heck we have three tv's with the same power board in the family. One at my house and two at my mom's house. One was in her bedroom and the other was in the bedroom of a special needs grandson that lives with my parents. Not my child but my older brothers child. It was the special needs grand kids that died so we took my mom's good board and move it to his tv and order the board for my mom's tv. So we new it worked before we remove the board from it. There seems to be a 75" onn tv now with the same board as well. Look at the photos and it looks almost the same just the color of the heat sinks changed. same part number on the board.

My ONN TV 65" will come on and just freeze on the Logo screen. I've gone through the reset process (reset button), updates and reconnection to my wireless internet and it just goes back to the logo screen. I'd hate to toss it if there is a board replacement option, but I'm thinking it's not the power board because it does instantly come on then stick on the Logo screen.

I would think it's the main board with the tuner and all when that happens.

Can I ask if you bought the bad boards from "shop jimmy"? I've bought 2 and they were bad. Who did you get the good one from?

@JUST_ONE_ID10T 2 ай бұрын

I only got one bad board and it came from a guy on ebay. I knew it was a bad board as I had two of these tv's so I had another known working board to make sure that was all that was wrong. Then the next seller I bought from sold me a good one.

there are many of them on ebay just not the same ebay link. Search onn and the model number also it seems the onn 75" also uses the same power board. Just make sure it has the same connections. i think they change the color of the heat sinks but other then that they are the same. They have the same part number.

be careful as the board holds voltage even when unplugged and I shocked the crap out of myself with it. you can take a screw driver over the caps and de-charge it.

@shawnstiefel6845 6 ай бұрын

It's great you show people this but please don't ever check a board for power with a screwdriver again! You might have been safer to handle it but you take the chance of blowing up the new board. Especially if you shorted out the hot side with the cold side. If you don't know what that means you shouldn't be messing with these. Use a volt meter to test for voltage. Some of these boards have in excess of 400 bolts. You more than likely screwed that board up and now whoever you got it from has proof!

and an FYI it was got for my mom. She has two of these tv's and it's still working great. and the old board that didn't work correct still had voltage in the board as well that is what i was warning people about is to be careful with the boards as well as they can store voltage in the caps.
