Hi,

I have an old Pioneer Projection Monitor (Pioneer SD-P 6081) with 3 tubes. I currently am getting sound but the tubes are not getting hot and I don't see anything on the lenses (all 3), what could be the cause (since all 3 tubes are not working), something on the board? Also, when I unplug the power after a while, I hear a noise coming from there that sounds a an old CRT screen cooling off (tssssss), possibly coming from the tubes. However, the tubes are cold.

Please let me know what you think!

Robin
