Hi

If 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;

1. Trace from vga to video section dont
forget to resolder ends of that.
2. Hang all the pins of vertical IC and find the
B+, bottom of flyback pins the negative
prove 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,
suspect your flyback transformer
is deffective.
NOTE:
Deffective flyback & Vertical IC can
cause of blinking LED.

17" flatron crt monitor only green led blinking and tick tick sound .No display


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

AOC color monitor model 5En...during power on all led lights blinks then stops blinking without display action. all led lights on no more action observed.


actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

Syncmaster 2232gw led blinking.


Change the screen resolution. The video card or video display may not be compatible to the supported video setting of the monitor. Try changing the video resolution to a lower setting such as 1024x768 and bit depth to 32 bit.

Green light continously blinking in samsung sync master 753s


1. cpu problem. why because of there is no signal output from cpu to monitor. the led blinking means there is no vertical, horizontal signals from cpu to monitor.

2. your monitor connected to another system.

3. neck board dry points.

4. cheak the display cable. 13&14 pins are horizontal, vertical signals.1, 2, 3 pins , R G B , 6 ,7, 8 pins R G B ground ( coaxiler cable used , meshed wire is ground )
