The montier turns on then turns right off
Hi!
When a monitor display image for a second and then goes to black screen... there are possible reasons why this problem
occur..
1. You need to check if the high voltage ballast
transformer of your backlight inverter is about to be burned... the
transformer is overheating..that's why you experience the monitor
working for a couple of seconds and then it will shut off until the
transformer cool down again and then it will be ready to work again...
2. Check also the backlight inverter if it is busted...the backlight inverter is the light source responsible for the image display you seen on your screen. If this are busted then all that you will be seeing is black screen
3.
You need to check the power supply section for possible loose
connections and possible blown and bad capacitors..
the ballast transformer has direct
effect on power supply section.. when there is overheating
transformer,,, the supply current from the power supply section becomes
unstable.. and will not be able to supply the remaining good working
ballast transformer.
In case you do not know, the ballast
transformer generates high voltage for the backlight inverter to
work....
Please be advise that if
you don't have the knowledge, the proper skills and the right tools to
open the back cover of your monitor and replace its part...don't risk
it...
Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....
Much appreciated if you rate this help...thanks...
