H Series 64 -65 main board upgrade

[j911]

Hi,

I am after a Samsung UE40H6500 in the UK but it has been discontinued and no longer available, however quite a few retailers still have the UE40H6400 model in stock.

I plan on using it with oscam and record to USB HDD hence need for twin dvbs2 tuners.

So im planning to buy the H6400 and replace the manboarf with either H6500 or H6700 whichever is reccommennded.

Can somebody please confirm if that would work? Main board layout is the same only not sure if it would work with the display panel.
Part numbers are below for the mainboards:

UE40H6400: BN94-07309 R or G
UE40H6500: BN94-07457G
UE40H6700: BN94-07457L
