Mainboard Swap for HU7590

Hi there,

recently i flash downgrade fried my UE65HU7590LXZG.

So i wanted to prepare a swap of the Mainboard with a new (used) one. I found a very cheap Mainboard for this exact UE65HU7590LXZG and ordered it. It will arrive in the next days, but now i am unsure.

The Mainboard that is currently in my TV is:

BN94-07937E, the sticker also states it is for this Model: UE65HU7500LXXN

The Mainboard-Replacement which will arrive here shortly is:

BN94-08287G, the sticker also states it is for this Model: UE65HU7590LXZG

So i am a bit confused, that in my TV is not the exact Mainboard i would suspect. Do you think this swap will work? I can also order a replacement, that matches the currently installed Mobo, but it is quite more expensive.

Should i even try this swap or could the wrong Mainboard fry other components like the T-Con? Visually the both mainboards look exactly the same.

Thanks in advance!

Surely harmless, but basically nobody knows :)

Hahaha okay thanks ;-)

Will try it then, and if it does not work, well bite the bullet and buy the expensive replacement-part ;-)
