I'd post this along with your TRANSACTION NUMBER from your call to 1800SAMSUNG to the CNET Samsung Forum. The Samsung Ambassador does take the weekend off so you have time.
I have a 61" Samsung DLP television. The only buttons on the remote that
work are the power and volume up/down and channel up/down. On the set
itself, the power button does NOT work but the volume and channel
buttons do. The menu and source buttons don't work in either place, nor
do the numbered buttons on the remote. I have tried new batteries, a
different remote, unplugged the set two different times for over 8 hours
each time......still nothing....HELP!!!
Although, I did forget to mention, when the bottons on the remote are
pushed, the light on the TV blinks like it is responding to the remote,
yet, nothing happens.
