Hi
\015\012
\015\012If your monitor connected to pc check the vga cable, video card and try another monitor to prove it to yourself the monitor is deffective after you change it but same probem again.Do it;
\015\012
\015\0121. Trace from vga to video section dont
\015\012 forget to resolder ends of that.
\015\0122. Hang all the pins of vertical IC and find the
\015\012B+, bottom of flyback pins the negative
\015\012prove is connected to hot ground of horizontal then voltage B+ with red prove of tester range 250v DC i think the normal is 100 to 175v if you encountered over voltage,
\015\012suspect your flyback transformer
\015\012is deffective.
\015\012 NOTE:
\015\012 Deffective flyback & Vertical IC can
\015\012 cause of blinking LED.
