Hello Everyone! I Have a couple of Durabrand DBTV2500 tv's that have repeat failure of ic 501 str30110 reg , R506 20w , R 508 and Q 401 hot. Both of these sets ran about a month and are back. Same problem. Has anyone out there found the cause . I have checked a variety of components in the reg circuit , and other than the parts listed everything checks out fine. Any help would be appreciated.
