My proscan tv has the blue light but wont turn on
Most likely it's the power supply board that went out. (part of it still works is why you get the blue LED when you plug it in.)
If you decide to try to fix it yourself, BE CAREFUL! The power supply board has capacitors that can hold high voltages for many hours after the TV's been unplugged.The equivalent of sticking your finger in a light socket.
You'll need the part number off the power supply to get a replacement.

Try another set to see if does the same - if so, then it is your box. If not it is the tv. If still under warranty have it fixed before the no sound becomes permanent.

Why is there no sound?
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. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. Surf the site with patience.

Why my Pro Scan TV has sound no picture
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

How can i get rid of the run scan message?
Run the scan. If that does not do it see if you can reset the electronics to default condition. Many sets have a reset switch or a combination of keys on remote to accomplish this. U might have to check on the web site if your manual makes no reference to either of these alternatives.
