hi,

This monitor smoked. Upon inspection I discovered decayed glue that
became conductive. So I cleaned the board and replaced all burnt
components and also check semi-conductors. When tested it connected to
a system unit, the light turned to green but the screen is blank. I can
feel static in front of the monitor and the heater glows. After a
minute, it suddenly clicked and the display comes out. Restarting the
computer returns the monitor back to blank screen. So what I do is to
turn off and back on the monitor several times until the display comes
out again. One more thing I noticed is when turning on the computer,
the monitor automatically turns on also. I suspect that horizontal
drive is absent and after a moment, it sets in. What components I am
missing here?
Any help and suggestion would be greatly appreciated.

ian
