I have a Sony KP-53V85 does not power up. The fuse inside is okay. Perhaps it is the power supply. Can I check this myself with a voltmeter ? Where would I test it and what should I expect ? I may need to get repair person eventually, but I would like to diagnose the problem myself. Any help/hints will be most appreciated. Thanks.
