How did the DIGI boy get in here
Just kidding.......
ALL Barcos (im not sure about cine9 or 909/919) switch the fans off when in standby mode.
Now for me I would prefer to leave the projector in STANDBY mode.
this keeps basic controls running such as main processor and I think the 8v power line.
This means the Power supply is NOT fully off BUT also means that it will be warm.
THIS IS A GOOD THING - Heat cycling of electronic equipment, and POWER cycling all reduce the life span of electronic equipment - HOWEVER for some equipment this is the only way to use it.
OVERHEATING whilst we are on the subject is a killer of electronic components, I think its something like every 5 deg extra the life span of capacitors reduces by 25-50 per cent - this is OVER the recomended running temp.
BARCO projectors do NOT COUNT standby hours (Marquees Do so I am told).
SO for me KEEP your BARCO in STANDBY when not in use.
(LCD/DLP type projectors switch into standby and run fans for approx 5 min, this is to keep the ELECTRONICS cool as the LAMP will still be emitting heat after power down, this also keeps the LCD display cool during this time so it can be in good order to produce pixels on its next use
