TC-P50G20 SC Board Repair

[Robb]

Hey now, I found a fried IC (C0ZBZ0001708) and transistor (DG3D5020SLW) on the SC Board and confirmed the error with the 2010 FHD Plasma TV Troubleshooting Handbook's resistance test on the P15V circuit. There is no other visible damage to the boards. The error light code is seven (7) blinks which indicates SC Board. I plan on testing the SU and SD Boards before retesting the SC Board after I swap the new components.

Apparently, the parts are not available when referenced by Panasonic's part numbers but I found some references here on badcaps.net, to wit:
IC16521 C0ZBZ0001708 IC 1 M81737FP
Q16403 DG3D5020CSLW TRANSISTOR 1 DG502LW

I used the above highlighted part numbers and ordered them.

I have two questions that I hope to find answers to:
1. Do I have the right part numbers?
2. Aside from the SU & SD Boards, are there other parts/components that commonly fail along with the IC and transistor that I should/can check?.

Thank you kindly.

Are there any other FETs near that FET? Does that IC drive more than one FET? Have you checked the gate series resistor? (usually inbetween the output of IC and the gate.)

Search TNPA5081 and read my post, I'll be amazed if you get it going with just those 2 parts but maybe your the lucky one.

Thank you for the responses. Since I should have posted this thread in tw2005's "Panasonic sc tnpa5081 rebuild", I decided to move this one over to https://www.badcaps.net/forum/showth...26322&page=11&
