Is This Samsung LN32A450C1D Worth Repairing?

[lkvee]

Friend found the TV lying on the curb before garbage day on his way to the Fixers Collective in Gowanus, Brooklyn for a Fixing Session. We popped off the back and found quite a surprise.

Same attached pic is here:

I'm presuming the model number for the missing power board is BN44-00214A and I'm wondering if other model power boards can play nice-enough with this TV.

I'm not sure if other parts are missing like a T-Con board. I know smaller TVs will just have a power board, a main board, and an inverter board, but I'm not sure if this TV's one of them.

I'm not sure what part on the board can cause this type of larger-scale damage.

What else should I consider if I want to figure out whether this TV is worh repairing?

Thanks for reading!

Looks like it might have arced to the chassis, possibly after a power surge. Wow, I haven't seen one that bad before.

Unsure if extra damage has been done, could be expensive to fix. If you have a DC lab power supply, you may be able to test the main board by connecting the 13V and 5V rails.

Looks like everything else is in there.

looks like it got hot enough to damage the backlight defuser.

Basically, if installing a new (to me) power board won't bring it back to functioning order, then I will close things out.

Is a DC lab power supply also known as a bench power supply? Making a bench power supply out of a PC ATX power supply has always been a backburner to-do project for me.

Thx 4 the reply!

"Fixers Collective for a Fixing Session" perhaps a small subset would know what this is SMOL

The Fixers Collective is a group of tinkerers who help others get their stuff fixed up. It's 100% skillshare and participatory - the people bringing in things will take part in the repair process in one way or another. The collective meets once a month in Brooklyn, NY. They're looking to expand to other areas like Manhattan, too.

One of the "Fearless Fixers" always keeps an eye out for street finds. He found not only this TV, but also a Dell laptop (Studio 1735). I'm hoping the laptop just has a bad power button - there's no reaction when I press that button.

We looooooove getting LCD and plasma TV's and monitors because we also have a bagful of known-good-brand capacitors. We hope to move up and on to diagnosing stuff like transistors next (like the C5706 perhaps?).

Thanks for asking!
