Hellllpppp!!!
My Barco 9 will not power up from standby.
I was able to power up the pj by toggling the main switch at the rear continuously.So eht and quads are not the problem.
I have measured the voltages and tweaked the 17v and raster width a bit , but still the same problem.
The menu voltage diagnostics seems inaccurate so i measured the 17v points with a meter.
The measured voltage was 17v , spot on.
So now after tweaking those two trimpots, i was only able to power it up twice.
Now it just stays in standby mode only.
The leds on the g2 diagnostics board are on, but very faintly lit,when i press the standby switch from the rcu.
Seems like some caps are dry or failing.
I will be swapping in a good smps board later to rule out other boards.\
Hope to hear from you guys.
Regards,
Lars

Nice to hear from a Filipino here, sorry for the late reply.
Taga Malabon ako.
the outcome :
The barco just needed readjustment of the 17v rail, it is a combination of adjusting the h width at 85 and projecting a white raster ,then adjusting the contrast and brightness at 50. Then readjust the smps at 17.5 volts.
A lot of guys PM'ed me and sent me the the service manual, and also got help from Curt himself and also from Mike P.
keep sending me posts.
