As with another post I saw the LCD appears to get a signal, power button changes from amber to green (& have access to on screen controls) yet no display even at post.
The LCD is a 19" ADI A905 it has both DVI & VGA. I currently use only VGA, as that is all I have access too. and have tried it on several computers.
It has worked well for several years, but in recent months would ocasionally not wake from sleep without turning off/on or disconecting/reconecting Power. Now no display.
I was wondering if this is a fixable issue?
Bad VGA Cable?
Bad PSU (Brick)?
Bad Setting? can firmware be reset or upgraged?
Bulb/? needs repacement?
Any sugestions are appreciated.

Note: Unlike CRT monitors, which requires a high refresh rate to minimize flicker, TFT technology is inherently flicker-free. If possible, configure your computer for 1600 x 1200 addressability at 60Hz vertical refresh rate.
Use the following table as a guideline and reconfigure your computer to use a supported display mode. The highest resolution (for example, 1600 x 1200) produces the optimal output, but limitations of your monitor may prohibit this setting. Adjust the addressability mode until an image appears.

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
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.
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
If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional
ILLUMI BLUE (Initial setting) / ILLUMI GREEN/ILLUMI AMBER /
You can change the lighting color of the following four buttons:
SOURCE/POWER, BAND, (left << arrows) and (right >> arrows).

buttons is AMBER/RED, the color of the others is AMBER. When
the color of the four buttons is BLUE/GREEN, the others are also

If screen says "Signal cable not connected " all the time till power led switches to Amber chances are monitor is ok and problem is with graphic card or cpu.Connect to Known working CPU and confirm that monitor is the problem.
If same problem persists on another working cpu after changing signal cable,the interface board in the monitor could be defective.
Your TV is probably on the PC mode and you are not using it as a PC monitor.
You need to change the source by pressing the TV/Video button on the remote control or the SOURCE button on the TV itself. You may also just press the channel up or down buttons. Do this before the TV goes to standby mode (amber light) or while it shows the message: ATTENTION NO SIGNAL.
If it does not work, reboot the TV first and do this again.
