ZSUS Board replacement....	Can't Post

I have a LG 50PY2R Plasma which is nearly 4 years old.
Few days ago, it made a big bang and the picture went all distorted.
Power still comes on.
I have opened the TV and got a electrician to test, and he tells me that the ZSUS board is at fault.
Part : 6871QZH044A
This TV is one of the first 50" LG plasma that came on the market. Ive been told that both YSUS and ZSUS are combined on this board, unlike newer plasma's which have 2 seperate boards.
Is this correct?

Thanks

No, I just looked at the service manual and it has both y and z boards.

Hi, having a look at the TV again, it does have both Y and Z SUS boards.
Here is a picture of the TV on...

Update :

I found a local TV repair shop which i sourced part from :

Swapped out the Z SUS Board - Still same issue

Swapped out Y SUS Board - I get no Picture at all (maybe the swapped out part if faulty?)

Next step...could it possibly the CONTROL Board that is fault?
