changed 200m to 2m.

I made a mistake on pic above. Its not 200M its 2M. But overall it fits.
btw I cant find what is red-red-gold-gold-white. We need some1 to explain.

This is a big help. I'm away from it until Monday, but I'll answer the questions I can remember.
To optoc? Yes
20 oh? Bands on resistor are red-red-gold-gold-white. Which I think means 2.2ohm. (see picture)
Source to gnd? I don't think so. I checked for shorts, and I think source wasn't connected to ground.Attached FilesLeave a comment:

I don't know will it help or not.
This is from CM6502UHH PFC controller typical application circuit and it has TNY227P.
Resistor is 2M (r45 + r46). On your photo something is behind.
My wild guess it is sort of hz15-2. Enable pin should be connected to optocoupler.

Have you ruled out that it isn't TVS diode P6KE150A (VR1) or Zener diode 1N5254 (VR2) from the example schematic you posted? (By studying the actual circuit closer/drawing it up more it should be "easy" to see).Leave a comment:

Corsair RM1000e - Help identify 5VSB Zener diode
Hey there guys. I've got a Corsair power supply that's come across my bench dead. I usually don't mess with power supplies, but it's a slow week so I'm giving it a whirl.
Taking it apart I heard a screw rattling around inside, and when I got it apart I found a couple blown components near what I think is the 5VSB area.
There's a 22ohm resistor that's melted and open, but it still has the bands.
The other part is a zener diode and it's top went to jesus, so I can't read the marking.
It looks like the diode connects the source and drain of a TNY284 through a couple of 2M resistors and a transformer winding.
Does anyone know what a good value for this zener would be, and what it might be doing?
Any help much appreciated!
