Hello all,

This is a 19" Compaq monitor with a startup problem. When first turned
on, it appears completely dead. However, there is a very faint ticking
sound coming from the power supply, and after half a minute or so the
monitor just springs to life. I suspect a bad starter cap in the psu.
Could anyone point me to the right one, or should I just replace all
the small caps in the region?

Thanks, ile

Well, replacing C843 and C844 cured the startup problem, but now the
monitor clicks when in standby... Did anyone ever tackle this one?

BR, ile

Never mind. Replaced C862 and the clicking is gone. I only had 47u 63V
available so I used it, guessing that the capacity didn't matter much
in that circuit. The standby led blinks in both green and orange, is
this normal for this model?
