I have taken apart my Samsung TV UA32H4303 and found that there’s a burnt mark on the power supply circuit board BN44-00767A. I’m wondering if i can still fix it? Not too sure how to upload a picture here, but here are two google drive links to see the damage.

Seems like it’s a old model and is no longer in supply. Or if I can replace it using another circuit board with a different number? Update (07/02/2018) Hi @oldturkey03, Thank you for your speedy reply. Glad to hear that there is still a chance to repair this. You’ve asked for the underside of the board, is there anything else I should take note of? The google drive link to the picture:

@ken1303 the component that failed is a bridge rectifier. You could try and replace it and see what happens (always buy 2 just in case it blows up as well) The part should have an identifier on the case. Post some pictures of the underside of the board as well. There is a reason why the rectifier has failed. The power supply is still available at places like ebay.com and others.
