My monitor is not turning on. Only blinking lights on the power switch. any suggestions?

hard to turn on, power supply failure replaced bulged or blown electrolytic capacitor. you can find replacement parts at www.digikey.com.

most of the time the blinking is a form of error message from the monitor depending on how many blinks in between each pause lets service technicians know which breaker fuse or transistor needs to be replaced
I would suggest taking it into a computer repair store and have them attempt to fix it however alot of the times its cheaper to just buy a new one

Hope this helps

check the capacitors inside the monitor, as they may be broken, and they start screen up, just change em and it should kickstart fine

If the power supply is coming to CPU before activation of CPU then it must be receiving current from UPS. Don't try unplugging, You may get shock. Thank you, Sir.

make sure that all the cables are connected FULLY.
blinking light means that there is no signal.

The monitor requires service The monitor is not receiving a signal from the computer

Check the resolution in the Windows while connected to the old monitor. If greater than 1280 X 1024 and/or the refresh rate exceeds 75 Hz, the monitor may not respond. But you should at least see the BIOS splash when the computer is turned on. If that does not appear, maybe a problem has occurred in the monitor. Another indicator: if you turn the monitor power button off and then back on, you should get some sign of life such as "no signal", or "out of range". If nothing appears, that would indicate some problem within the monitor.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

resit your ram if the problem perssit then remove the video cable which is attaching to the cpu,check for any message in the monitor(monitor should be power on),if you are getting any message then your motherboards's display adapter has malfunctioned, send it for repair

According to the manual for "POWER/STANDBY indicator is blinking in red":

• "The temperature inside the main unit has become too high and has activated the protector."
• "Promptly switch off the power of the main unit ans wait until the internal temperature drops."
• "If the monitor becomes too hot, the overheat protector will be activated and the monitor will be turned off. If this happens, turn off the power to the monitor and unplug the power cord. If the room where the monitor is installed is particularly hot, move the monitor to a cooler location and wait for the monitor to cool for 60 minutes."

I'd suggest looking at the mainboard. I assume the blink is rapid? A slow on, followed by a short off and back on again is normal. The fast blink thing is a mainboard issue, and the absence of blink (or light) is power "supply dead."

There is a problem transistor on the mainboard that seems to be the problem most of the time. Replacing it takes about 5 minutes if you have the tools and the talent, and the parts cost under 3 bucks at Radio Shack. Just pick up a pack of NPN switching transistors and de-solder / solder your way to a working monitor. There's usually only one on the board, so it's easy to spot.
