Re: Sony Vaio VPC-SB26FG cannot power on

hi all hope are very well tell them that I recently bought this laptop second hand worked well but I can not turn on

searching the internet reaches the conclusion that it was the same failure cnx-458 series and vpcsb vpcsa as discussed here

the problem is that I have not been able to find out which component is failing and I was wondering if you could guide me a little to find the faulty component these are the readings I get

in advance thank you very much have a great forum...
