Model 37MF321D/37 TV with power board 715T2056-1 issues. Capacitor at position 2074 (overheated and self vented) has been replaced with match. Diode at position 6079 (was literally baked onto the board) removed solder. When I tried to replace with new diode, part of Cu track on back of board flaked off. Main question being: Can I jump to later circuit, or can board be replaced with board from different manufacturer with same connections?

Follow the trace wire to the next component and jump it.

Do you know the part number of that diode or maybe just the values?

Same issue here...replaced 2074 and diode at 6079 but 3045 appears to be damaged.

Anyone know what should be there? It appears melted and I can't read it anymore.

I too am looking for 6079 and 3045. I see the post above identified 6079, but does anyone have a clue about 3045?

I'm interested in this information too. What is the replacement part we need for 3045? Also, thanks for the 6079 part number. Hopefully I can have this thing up and running again soon.
