Hello again.
In case if you would replace fuse (it's one of two ceramic slow-burning fuses installed in holders next to each other) and it woudn't burn but TV still have no image - that means that both Z-Sus and Power Supply boards are bad. If fuse got blown again right away - usually indicates that Power Supply board still OK and does not need to be replaced.
Before go ahead and order Z-Sus board, visually check out narrow buffer board that attached to it. On other end of it you will see several flat ribbon cables that go into Plasma Panel. Make sure that you will not fined any cracked (exploded) microchips ot other electronic components or burn marks on it. Sometimes short in buffer board can cause Z-Sus short out as well. If everything looks fine - replacing just Z-Sus board would in 95% cases repair your TV.

Get in touch with your cable operator and measure the strength of signals being received via the Cable. It can be boosted by the cable operator from their end or attach a booster on your line...............sodeep
