The board change is a bad move fix the issue

Oh i see. it was my little cousin that accidentally push the ok button when the update notification suddenly showed up , i've already turn off the auto update but sometimes it's still appear randomly. The previous firmware when the picture is still excellent is 2140 and the current firmware after update is 2180.
My friend also has the unused H6400 tv but his version is the 48 inch and the firmware is 2140 i've also check the mainboard type and its the exact same as mine that's one of the reason that makes me consider about swapping the mainboard. is there any other solution to bring back the previous firmware?

You could probably try a reset to Factory settings.....I don't know if that will work.......

You need to access service menu and change the panel type when going from different size panels
worth a try

Maybe get into service menu with your board. Figure out panel type. A maybe bit or panel type changed?

The first noticeable issue is the change of the picture characteristic now the picture becomes more darker and dull than before its like it has lost a lot of contrast and brightness and also when watching a HD channel or movie from usb it doesn't feel like a 1080p HD but more like watching a 480p resolution noise and jagged everywhere. second issue is that the Tv wifi easily disconnected by itself randomly.
No matter how hard i tweak the picture setting it still can't go back like before it was
