Hi

The Jungle IC is a TDA8361, I dont have a scope unfortuantly but all signs seem to be pointing to the Jungle IC being at fault, I've replaced every component in the vertical output stage, the voltages going to the Vertical Output IC are correct, It seems that all thats missing is drive which comes off Pin 43 on the TDA8361, wish I had scope just to confirm.

I Have a TDA8361 spare that I could use, I've been putting it off hoping it wasnt that (I hate soldering larger IC's, tiny pads and a crap soldering iron make it a long process) Im going to change it anyway and fingers crossed that's the final piece to this puzzel.

It surely couldnt be anything else could it?
