Re: Vizio VP50HDTV10A; replaced caps and still intermittently shut off and cycles on/

try heating components with hot air gun and spray some freeze coolant on PSU board to see if it will work fine.

Re: LG 50PG20 plasma no power issue

then start by measuring the voltage on the input PSU connector on the primary hot side with your DMM set to ACV range with the set plug into the AC OUTLET. also check the fuse next to the connector.

Re: Help identifying part on samsung lcd main board

117-25 or 17-25? because I only know 117-25 is fixed regulator 2.5v output, but this 17-25 I'm little confused here
