KDS RAD-5 Screen flicks on for an instant, then goes completely dark; lighting it up with a flashlight I can see the screen there, looks like it's missing a flashlight inside there!

Sir,
first port of call is to right click on a blank bit of the desktop and choose properties from the menu,you should find a section with your monitor refresh rate on it,this is usaully set to 60hz by default,75hz or above should get rid of flicker if your monitor supports higher.....failing that,have you got anything recently placed near it that could interfere with signal such as a mobile phone?.....also check cables for condition and plug is secure.......if these fail you might have a fault developing in your graphics card or if its a TFT screen an ilumination tube maybe faulty inside the screen


Thanks Good Luck
Appreciate to rate as "Fixya"

Replace the inverter circuit board for the hi voltage supply to the back light for the LCD display.

Its the light inverter fault needs replacing.

That means that the inverter is gone.

When back light inverter got defective, monitor behaves like that.
You need to replace back light inverter board for continues operation.
