HD TV repair question

[Dozer]

Hey folks looking for some advice on fixing my Samsung 55" (Model UN55D6400UFXZA). Without going into details I believe my problem is the System card.
Here's my problem the part # on the System card is BN94-04869X and it appears it is not a valid number. I've Googled it to death and checked every website that supplies TV parts...nothing.
I've looked into what is the recommended spare for that TV, (BN94-05038N) and they look very similar but they are not the same. All the connectors on the board are identical but there are some differences near the center of the board. Chips don't match up.
All these websites have an almost identical warning. Don't order parts based on model numbers only use the part numbers that are actually on the boards.
I'm fairly technical (15 yrs with IBM), I have a feeling this two boards are interchangeable
but does anyone have any real life experience?

Thanks,
Dozer

Have you googled your symptoms yet? Google the symptom and then look at the uTubes on how to repair. Most Samsungs have problems with the power supply (different colored dots on the screen, colored lines, etc). You can buy parts, usually a bag of new capacitors, to repair the power supply on eBay for 10 bucks

Hardest part is getting rid of the old one... Costs me $25 to dump a 27" tube type monster at a garbage dump.

Well the board was under $200...but I hear you!

Should have gone to the Black Friday sales and got a new TV. Probably cheaper than that board. $299 and up for 55".
