This 2001 model projection set has a tough problem to track down, so I'm
hoping someone can give me some advice. Fuse F850 (5A), in the power
supply, will blow at random intervals - sometimes when trying to power up,
or the set might run fine for hours, days, or even weeks. Just thought I'd
check for any known issues with this set, before attempting what could be
a long and frustrating job.


You could temporarily substitute an AC ammeter for the fuse and watch the
current. Alternatively, you could use a large fusible resistor, say 1 ohm at
10 watts or .1 ohm if you prefer, and monitor the voltage across the
resistor. Should give you an idea what the current is doing.
