No sound, picture fine. Worked fine last time used. Tried Audio controls to ck for speakers either on or off. Can't get remote to change the state from on to off or reverse. Attached external speakers just in case TV speakers turned off. External don't work either. Any ideas out there?

Re: No Audio, picture fine
This is a very common problem just unplug tv for 5 minutes it
should fix it . simple fix most of the time with rca and proscan.
If that does not do it go into menu scroll down to audio and then press on .

I had this problem too. Finally, after using the MCACC setup and making sure all the speakers worked, I found I had to set the source to FM, TV or whatever from the remote control and set the mode to advanced surround sound using the front panal button on the upper right. Had to fool with them a lot. Good luck.
