@acblunden2 yep that's exactly what I did.
Alrighty, will give it the good ole' college try and have an update by the weekend.
Additionally, the vertical deflection IC I pulled out of the PB7534-1 is clearly 'LA7838'. LA7837 is what I bought from UTSource. Let's hope this works. I'll hang onto LA7838 just in case. Will report back then too.

Seems to be the same part, with the datasheet saying the 7838 can be used to deflect larger screens from 33 to 37 inches. I had based the part number on the part on my personal chassis.
Careful with pulling out / resoldering the deflector, it was in a zone most affected by capacitor leakage and alot of traces were corroded on mine.
if someone with a working windy 2 psu can read the 3 diodes that are on the board th that sits next to amp let me know the values
Diodes always start with 1N#### for part #s. Its how they are identified on the body.
With those numbers on the paper can you till me what I need to look for I'm a little lost on this
@acblunden2 Finally! Have fun!

@acblunden2 wow nice work !!!!!! Glad I could help. 
What's more, the flyback on the right is the one that came out of the Windy II Toshiba PB7534-1. The flyback shown on the left came out of a tri-sync cab that is known to work. The are identical flybacks. Guess what chassis that flyback on the left belongs to?
Right you are. But thus far these flyback have been explained to work in the MS2931's. But that is an MS2930 with pots on the remote board instead of momentary switches. Interesting that the Toshiba PB7534-1 doesn't have the goop issue.
Well I guess that isn't groundbreaking. But I bought a few extra flybacks for spares. Sweated it because turns out the monitors in the Blast is an MS2930. All good now!

The goop isn't from the flyback. It's from a different component.

Goop is from a neighboring component of the H.O.T.
So that basically confirms the Chinese flybacks will work on both ms2930 and ms2931 chassis right? By extension most likely the ms2933 too since it is a 'bug fixed 2931'?What's more, the flyback on the right is the one that came out of the Windy II Toshiba PB7534-1.

Congrats on getting your PB7534 running, that's awesome!!
