hi
sounds like the psu, which ver have you got ?
if its a 17pw15-8 psu these give lots of problems, try c878 + c877 first
good luck

hi
the next thing i would try is the main smoothing block, they seem to be failing more often as the sets get older, but if not these power supplys are pain in the arse, search this web site there are lots of posts , i have posted quite a few solutions, you could also try q818 + q837 as the smd transistors also give int problems, but my advice would be suspect everything, spend a day on it , then if no joy , buy a new one, there not expencive.
good luck

fixer1:
thanks for that,have previous tryd the smoothing block,but no change not tryd the smt so will try that nexe just like to say thank you v much for the help,will let you know how i get on
