Good afternoon I have a Panasonic akx54 sound system that is the second time he arrives at the workshop the first time as with the mip2f2 regulator exploded that time just replace the regulator and the client worked perfectly. It took about two months and the client takes me and tells me that he turned off and did not want to turn on more. When checking it I could see that the mip2f2 regulator was exploded again to others I could see that the van of 550uf for 200v. I was inflated. Replace regulator and filter but this time did not turn on. That the voltage to start on pin 8 of the connector and there are 3.2 v. On pin 4 of the ic701 there is no voltage. someone who can help me give the solution would appreciate it.
