helloFive blinks - AKB circuit (automatic kine bias), the
timer/standby indicator blinks for about 30 seconds then goes to the
self-diagnosis function. Something is wrong with the video. Check video
out, Q705, 732, 761 and other components on the C board, also check
Q218, 219, 220 on the A board. In addition, unit could be in IK
blanking, try turning up screen slightly.
Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.
The monitor you have has bad components on the circuit boards inside. This is a classic problem with all LCD monitors. I rebuild them on a daily basis so I recognize the symptoms. I would suggest finding someone who can do component level repair on the circuit boards inside. I also suggest not trying to repair yourself as there are many breakable components to them as well as components inside that do not like static electricity discharges.
i just finished repairing a 20 inch acer monitor that had the same issue.... you have to take it apart and examine the power supply side of the monitor. there are capacitors that go bad on that board. you can tell be feeling the tops of them... the feel rounded. replace the capacitors and put it back together and it will work fine
i have one too and it always turns itself off at least 15 times a day and a red light comes on at the back and the screen is blank. It hangs up on people half way through phone calls, and tells me i have messages wich i don't and comes up with blank messages which i can't delete!! Today it has done the exact same thing again but it has been frozen for over 3hours i have tried taking the battery out and nothing works :(
