This set would come on then go immediately into shutdown, found the 15v line was being loaded down to 5v with a peak voltage test. solution, replace the 2200uf 25v cap (C155). note this cap would value check OK but shows bad with ESR check. I have seen the same trouble with PRO-99 but different cap off the secondary of SMPS transformer. Tony Saracco TCS ELECTRONICS 406 Andra Ct.
