new problem, my meter slipped when checking the voltage on D405, dont know what it hit, probably the horizontal line pin, there was a sqeak and the set shut down, it comes back on but no pic, standby led dimmer than usual, Ive got a horizontal line if i turn up the g2, no 26v coming off Pin 5 of the flyback for the vertical. 110v going into the flyback at Pin 3.

Is the standby LED still dimmer than before your probe slipped? If so, is the 5 volt line that feeds the Standby LED OK? I am assuming the circuit in post 63 is correct for the electronics in your set.
Keep at it.

Hi
No the Standby LED is normal now, the manual that i posted is as close as i could find to mine, theres 5 different manuals for this chassis (seems theres different variations of it all with the same name GT9313) some of them list different value components to what was originally in the circuit (for example: C434 in the manual is 220uf 40v but in the set was a 470uf 35v) I think i may have two of the resistors in the feedback wrong value, R417 in the manual is a 100K but turns out when i went back over the parts i removed its actually a 120K that was fitted and R420 was a 2.2ohm not a 1.5ohm.
Im going to order those correct resistors and see if that helps as was suggested if the feedback the jungle recieves is wrong the drive will shut down, i think thats whats happening.
I'll keep at it until I get it
