DANTAX 50" PLASMA O1 HD

[mbu10]

well my tv went off and checked the back fuses everything fine
the tv powers on and makes a click from a heat sink marked ic202
sometimes pictures comes on for a second before a large click comes from this ic
(never did before and assume this is at fault)
problem is it is a lg screen and main board a sony psu and cannot find any service manuals for it
or where to get a spare board which i think is at fault
any help
thanks
