I am confused between the backlight diodes. Right side photos are from Northridgefix youtube videos and my own board. Replacing JH/D4 with V3 would be ok? If i‘m able to salvage JH as D4 replacement, would it cause issues? A discussion with Aliexpress seller gave insight that JH and V3 are same but D4 is different. Kindly share information from datasheets if anyone has. Thank you. Why do they even burnout at the first place? Are they schottky diodes? Should i also need to check filters and coil?
