On powering the monitor, power on led glow and goes off after 2 seconds

FIRST WE DO NORMAL AND LATER TRUE CAUSE.
gee that is normal on all monitors and by Energy Star laws too.
the monitor if the PC is dead or in speed mode, shuts of in 15 to 90 seconds, all do, every one. the monitor has self sleep, all do. everyone ever made did. even back to CRT days.


and the OSD button goes dead after. that. too. fooling the untrained.
here is the first tests, NO PC connected at all
power on see power light glow correct color
then see Viewsonic splash screen push the menu button now. quickly, if button dead hold it for 10 to 15 second to reverse the button lock now, see OSD works.

if you test the monitor on a good PC not in sleep mode the but working PC, your monitor is ok.

this monitor is very very old, 2004?
it has CCFL back lamps not LED<
and all fully used CCFL lamps are now no good, used 8yrs a day at 5years are no good. that is why we use LED back lamps now.
this is what they do: all do , used fully.
1: goEs dead forever, (vast did)
2: INTERMITTANT . (BINGO YOU ) OR INVERTER DEAD.
3: DIM BULBS (like me. lol)
4 TURN YELLOW FOR WHITE screens.
5: STROBEs. (FLASHes)

AND A VERY EXPENSIVE SURE, THAT. AND LABOR.

power on and power on led glows normal , not yellow or flash.
then this happens splash. attached, 2014 made.
then that tells you screen is NOT DEAD is it? now? here?
(PC is dead or missing)

• NO connections on 1 or more inputs.
• NO sync
• no signal
• OUT OF RANGE

and goes black screen NEXT,. if all that fails power supply is bad.
if all that works the menu button works for 15 seconds turned on with no PC, and also works on all PCs if connected to one that are all good and not sleeping. test the monitor on 2 PCs if confused.

Change the power socket its plugged in to.. if that doesnt help maybe you use it too much and it overheats so it cuts.

Hi,
I have got a hp pavilion dv5000, when I turn on it the screen goes blank.

Power led glows, I hear for a few time the fan, disk led flashes intermittently and also I feel that the DVD player tries to load.

If I try to click on caps lock or num lock, leds don't respond to commands. I tried the hard reset pressing the power button for 30 seconds with the battery and the power removed. Nothing to be done by connecting an external monitor....

What can I do ?

Thank you

Possible causes of "2 seconds to black" can be

a) bad caps
b) bad ccfls and/or ccfl wiring
c) bad inverter transformer
d) bad ccfl sense circuitry

2 blinks means - over current protection (OCP) , unit goes to the standby
mode then displays the 2 blink fault. Could be a short in the power supply of
any of the circuits.

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault and will need to be replace.

I advice you replace the picture board on the monitor, this will solve the problem and will never experience such thing again.

Take care.

Please check whether the power cable is properly inserted...

The power button of this model fails with time.You need 2 press it tightly and hold it till the LED is on....

try this...


Hope this helped...
