Hi,
I have a Comaq 150FS 15" monitor that has just died on me.
It was quite happily running at 1024x768 for more than 5 years.
Then out of the blue, it lost horizontal sync for less than a second, then
popped. I have found the main filter cap has leaked everywhere and a leg has
fallen out. 220uF, 400V
There is NO life from the monitor AT ALL. No power LED, no HV, no B+.
Initially I thought the HOT packed it in. I expceted to open it up and
find little bits of transitor all over the inside. However the HOT seems
intact.
Now I think maybe the power supply has died, due to the bad cap. However
this does not explain the loss of H-sync.
Does anyone have any better ideas?
Also a circuit diagram would be VERY helpful.
Thanks in advance
