Hi Larry, are you getting sound?

No: I don't have any sound but I don't have cable or any device hooked up but I turned sound up all the way and don't hear any noise at all. Oh yes 3 days ago I had cable hooked up and turned up sound all the way but didn't hear any sound at all.

Thank you for confirming,

Ask Your Own TV Question

not getting sound would point to this being a main board issue rather than a backlight issue, so I would go ahead and replace the main at this point. They are hard to find anymore but you can send it in for refurb here: http://www.ptselectronicsinc.com/ebt62012710/

I love this site! $9 instead of a repairman or new/used frig can't be beaten. This older woman will worry less now that she knows about this site. Bless you all.
