Magnavox/ Funai 24ME403V/F7

[Caleb]

Picked up 3 Magnavox /Funai sets yesterday. The first I opened had a bad 270uf 200v cap on the primary shorted no other faults. The second and third have the much more common zener/ mosfet failures. This set is less than 6 months old (November 2013) and already someone trashed it. This set has a shorted 36v zener (1n4753a) an open 1.2 ohm resistor and a shorted primary mosfet. My trouble is that the number on the ic doesn't correspond to anything on the web, it is a TK7P500 with a slight possibility of TK7PS00. Does anyone have a cross reference of a compatible part? or an idea of one that might work?

So I think I have found this part finally. It appears to be TK7P50D, if the standard failure of these power supplies holds true I will need a bunch more components as well. Will update as I get further along with this set.

Got in my parts order from digikey last night and got this up and running
Ended up with these defective parts

1.2 ohm 3 watt resistor
36v 1 watt zener
STD9NM50N mosfet was the closest I could find and seems to work fine
2.5 amp fuse
