Panasonic TH-42PZ70B Not switching on solved THANKS

[Grunder]

Good morning, Thanks to Badcaps for helping me solve the problem on my Panasonic TH42PZ70B. The set was not switching on.
Thanks to Tom & others who thrashed out the problem back in 2012.

The customer had looked himself and came in with a little tub of screws Photo 1
Removing of the Y main involved removing a couple of pieces photo 2

The errant Mosfet as Tom had said was short circuit (H5N2307) photo 3 & 4
I could not source the component locally, and could not even find a Datasheet for the component on the net.

I found an old Panasonic Y main pcb with a similar lay out. photo 5. I read Toms advice about the slight differences in parameters of similar devices, but effectively replaced the faulty H5n2307 with a 2sk3995. photo 6

I have run the set for two hours, and all looks okay. If it returns, I'll have to try source original or refund. photo 7 (sorry sun light/ picture quality)

I didn't do the upgrade either, reckoning that the part had failed due to ware & tare (set has run for 5 years plus), and not due to old/erroneous drive.

Thanks, you guys are a wealth of information.
