Samsung 460Px monitor turns on but no vidio signal going through. Screen turns from black to a dark blue meaning the unit is powered and I get a solid green light.

blue screen means 'no signal' or 'signal level is too low' whereas black screen means that there's a signal. Check your antennae, do a factory reset to your unit and then try initial setup.

the problem is not on the monitor your system unit is the problem...maybe the RAM memory,video card or very high resolution try to load in other monitor and down the resolution to 800 X 600..

Capacitors in the power supply or inverter are begining to fail. If the monitor has a few thousand hours on it, the tubes may be close to the end of their service life as well.

If you open the unit up, look for bulged or leaking capacitors- when they leak it is a dark brown or black residue.

Unless the unit is rather new, it may not be a cost effective repair unless you have the patience to do the work yourself..

Guest, You will need to "sub-in" a known-good monitor to prove your pc is working ok! If pc is ok, then plug-in bad lcd monitor and check ( test ) it with aid of a bright flashlight to see if you can see a very faint image of the WIN-desktop being displayed on the now "black" LCD panel. Every owner of "cold-cathode-fluorescent-lamp back-lit lcd monitors should know the "flashlight test" and understand what the results of this very basic test mean. Do some reading in my old (louie12fix) profile to learn how to do test. Hint: The very first thing I would investigate inside the unit would be the unit's "switch-mode-AC to DC-power-supply/ccfl electronic ballast circuit for the top two causes of power supply going into "partial or full" shutdown mode, trying to SAVE itself from a nonrecoverable catastrophic failure. e.g. sparks,smoke, fire!! 12fixlouie

there is no reset button on lcd monitors, check power cable first, if the blue pilot led lights but no picture, you might need to bring the unit to the shop for servicing..

The clicking sound you hear is the power supply board trying to start up, this indicates the board has failed. This is a common problem with all LCD monitors after a few years of use. Parts called capacitors on the power supply board fail and they will keep the power supply from starting up correctly. If you can solder then you can repair the board yourself. Here is a link to a repair guide with pictures and videos showing how to dis-assemble the unit and then what to look for and replace to rebuild the board and get the unit back running.

This blue light flashing means there is power to monitor bu NO video signal. No Analog or digital Video . analog is the regular plug for PC to Monitor, the other is HDMI digital or other digital. Check signal digital/analog means again: No video signal from PC detected.

Sounds like you may have had a power surge.??
Disconnect power and signal input.
Turn the unit off for 20 minutes or so. Check the outlet against another device. ( Light )
Turn unit on without connection to PC video.
If you get a no signal, you good to go . Reconnect. If you continue to get a flashing light on power button,
Check warranty, get it back to Samsung for repair.
Hope this has helped

line driver element defective. no repair possible, to my knowledge. replace LCD or ignore line.

If the blue LED ist blinking the monitor does not receive a video/sync signal. If the blue LED is on continuously and the display comes on for a few seconds and then goes dark or dim the backlight inverter may well be defective. The CCFL of the backlight needs several hundred volts to function.
