Monster is right Al. My guess is about 350#?s. We bought it in. You might call
this a update. I turned it on in a dark area and saw a faint vertical line then
shutdown after 3 or 4 sec. Turned screen voltage up and definitely vertical
problems. You could not see this in the customer?s house, just hi voltage came
up and no audio, no video. Hopefully this may help if some one has seen this
before. I called a shop in the next town and he is going lone me his micro fish
and monitor Monday if I need it.
