This is generally not a good sign, the power supply has been compromised, along with the inverter board and possibly the micro controller ic, In most cases it is cheaper to replace the monitor.

When i turn on my Dell Inspiron 2400 Desktop Computer why won`t it start.


Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?

The monitor itself is black, and the power light is changing color from green to yellow to orange and flickering.


Hi there!
Changing the monitor light from green to yellow/orange/amber means that the monitor is in power saving mode. Make sure that the video signal cable is properly connected to the back of the monitor as well as to the computer.
Hope this helps.

The on/off of pc monitor (LCD) is blinking.


Most LCD monitor (depends on the brand) power indicator light will either turn from Green to Amber, or flashing Amber, or flashing green, when it does not detect video signal feeding it. So it may be normal with your monitor. Are you haivng problem with the display? If it displays he pictue OK then there is nothing to worry about.

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional

Green-Amber-Amber Code?


I know that my post is very belated, but I think, will be helpfull for someone henceforth...
First of all, there is one "chronic" problem with LG monitors: solders. Check soldering of Video Amplifier IC303, Flyback Transformer, Q833( ! 210V) , deflection coils socket, Vertical IC601, XTAL X401 and so on...
In Your case, probably the cause of "green, amber, amber" lights is lack of 15V on the Verical Amplifier IC601. DPMS is activated, and monitor does not work at all, even power off.
Replacing Q912 (2SA1273) solve the problem. I replaced him with 2SA1680 PNP 1A 900mW 60V, and all is OK.
This problem is fundamental for ALL 17'' Flatron monitors, repaired by me (over 30).

Wish Happy Repairing!

Best regards, Ico.
