Re: Vizio P50HDTV20A No picture No sound

vizio jv50phdtv10a. jave picture no sound. I have digital output to my sound bar. The speakers just hum. it get ouder if I turn up volume and goes off if I turn off internal speakers . Cannot figure out why output to my soundbar is great.but cant get internal speakers on. Is there a fuse? bad caps on a different board. Also if there is picture of all plugs to power board. I replaced about 20 caps on power board adn there is a plug from the input board that can attatch more than one way . Fourth pinset from top left corner Thank you Vince...
