Hi, the T-Con is separate from the LCD Panel 6 screws, not a problem to replace but finding one is, usually from a 10-46 with faulty chassis!
BV 10-46 MK1 has a diffrent Panel Type as that from a MK2 this means a different T-Con,
I have a BV10-46 MK1 with faulty T-Con but I only managed to buy a T-Con from ebay for a MK2 BV10-46
MK2 has 3 HDMI connections
BV10-40 T-Cons can also use T-Cons salvaged from BV 7-40s
