Breakdown of T602, leading to failure of C607.
In most cases, replacing T602 and C607 will cure the problem, if further problems
ensue (geometry faults, repeat failure of C607 etc) then R512, R513, R514, C508 and
IC501 may have failed.
Failure of R512, R513 and R514 can lead to discoloration of the PWB. Repair the
PWB as necessary.
