Mitsubishi VS-60719 cuts on and back off after 5 sec (Help) please

Boy am I glad I stumbled across this site. I am having a problem with my VS-60719 I turn it on and then after about 5 seconds it turns back off. It is giving a code 2 3. I removed the back panel and when I powered on all the tubes were powering up then about 5 seconds later I heard a click noise and they cut back off. I have taken out both boards from the chasis so far I have noticed R5k43 has a black char look on top, Also D522(-24side) has a black coloration on the board on the end closest to R522, D972 has a black discoloration on the board around both legs, L963 has the same black discoloration under it. I have removed the convergence IC which is labeled STK393-110 I ony see the one. All the fuses look intact and not blown.

My question is this what should I do? Is the black discoloration normal over time on the board or is this a sign that I should replace these componets?

Thanks in advance for the help also my email address is [email protected]

Thanks
