Please check for bad electrolytic capacitors on both main board & power supply, if there is any "pup-up" one, replace it (them).

This is normal on vizios, ours does it too. You have it switched onto RGB input. You need to change input after it comes on. Switch on and keep pressing change input button till it changes and then it will be fine. Alternatively plug in a computer on Rgb and then turn on, you will be able to change input normally.

There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

remove all the screws and start at the bottom and push in the tabs, and work around the edges, being careful not to pry too hard, the cover has clips all around the tv. after the bottom is free and one of the corners the cover will kind of pop off if you use the palm of your hand and lightly tap as you apply sum upward pressure.

I looked up the manual for this TV and it has composite (RED, WHITE, YELLOW) and component (RED, GREEN, BLUE) connectors as well.

Are you using a cable or Dish box? If so, those boxes usually have output in Coax, Composite, and Component formats. You could just run that type of cable. If you use Component you will also need another cable set (RED, WHITE) for audio.

If, on the other hand, you do not have a cable box and you are using your TV's tuner you only have two options. You can repair the broken connector or you can route the Coax through an inexpensive VCR which will allow you to convert it to Composite cables. In this case, however, you'll have to use the tuner in the VCR, not the tuner in the TV to change the channel. Sorry it's not the best of news.

I want you to know that I'm not paid for this. It's a strange hobby I know, but I like to help when I can. While I cannot physically repair you TV, I hope you've found this information at least helpful and will rate it positively. If you have more questions please don't hesitate to ask. Thanks, and good luck.
