I decided to take it slow on this one after reading all the issues with two different versions of this chassis along with the solder side of the board being silk screened incorrectly for Cap Negative polarity...this is what I have and I hope the pictures are helpful.
Started out with no picture, no neck glow, tested HOT Q402 BU2532AL reads dead short all directions, pulled it, same 0 reading out of circuit, C423 was replaced at one time with part no. PMV924J 400V, inspected found cold solder joint and reflowed, found cut or broken wire at J131 between C409 & C406. Basically looking for pointers on where to go next, do this, don't do that scenarios.
