M65-F0 power supply issue

[EazyBone]

Got this tv, no indicator light plugged in. First check PSU

PSU has no stby voltages or anything, the main caps have 165 across them. I found this transformer (I believe) has all the cold side points grounded. Does this mean it has gone bad some way? The hot side isn't grounded at all points. Anyone know if supposed to be grounded here in picture.

Cold side will look like it's grounded because one side really is grounded...and other side, well it's a transformer and a piece of wire so it too will look grounded.
The second picture is really low resolution, can't really see anything but should look for the switching controller and go from there. Are there SMT components on the other side, or are all the semiconductors and other stuff just hidden underneath the heatsinks?

Thanks, learning still. Grounded all makes sense. All mosfets under heatsink except EL115/4/3/2 (clearer pictures now)

Basically need to figure out why no voltage at all on hot side. Octocoupler shows like .8v coming out which is clearly wrong. Gonna mess with multi meter tonight hopefully find something

Edit also no mosfets are shorted

Edit I also don't know what a switching controller is. If you have an example I would appreciate it

Have done more research and found that IC600 on back of PSU may be faulty, found a nick tv video, ordered one for $3 and will report back if it fixes
