Al;
This set has no Aux jacks on the back, so no speaker on/of in the Menu.
I'm going to try another Eprom, though. I noticed, that when I left it on
for about 45 minutes, sound would come on, but a low volume, when I tried to
adjust volume up/down....the volume didn't change, but when I got to the
bottom of the strobe...it would go off, then coming back up would come on a
specific volume level..but that has stopped again. So eprom may be a good
place to start.
Thanks;
