Samsung monitor goes blank after working perfectly for a period of time.


Have you checked monitor settings Carl? Some are set to sleep after a certain period of time. Mine was set to sleep after 1 hour (unknown to me) until I reset it. =)

Vaio LCD problem


Periods.......Nice little items because they denote the End of a sentence.
See how this works?

"I have a vgn cs36gj, I was working with it, suddenly the LCD became pale black, I connected it to external monitor and it has a picture, sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

Now you try it.........

"I have a vgn cs36gj. I was working with it, suddenly the LCD became pale black.
I connected it to external monitor and it has a picture."

Okay, I got that part.........

"sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

WHICH LCD?
Laptop LCD?
External monitor LCD?
Man on the moon LCD?

1) If the external monitor LCD goes 'pale black', the problem is the graphics chipset.
This I do not believe

2) If the laptop LCD goes pale black, this I believe.

Model hp1702 power supply ok inverter ok but connect the lcd panel socket suddenly off's? the green indicator light ...


monitor old very very old. 13 years old in fact.
this is a CCFL back lamp old monitor
so is the back lamp dead, that it.
does a flash light pointed to the face show a working
front panel menu button OSD data now? this is first to do.
OSD is always first then check the backlamps for DEAD.
that green lamp actions are covered in the 1703 manual
did you read that ?
i guess you meant the green LED goes dead? suddenly>?

ill read it to you.
https://www.manualslib.com/manual/767564/Hp-L1702.html?page=44#manual


that is not some simple monitor no,
it has its own processor inside, and that needs power too.
it must convert VGA video RGB top LCD data., all non trivial.

page 7

Power Indicator: Green - Power On mode.
Amber - Power Saving mode.
Blank - Power Off Mode

so if it turns its self off
that means the Brain inside sees gross errors.
or the brain side lost power.
there are many tests.
in a pro show we check all power busses, if the black lamps work
the connect up i2c to the I2c port and scan it for errors
this is what we must do to see if the BRAIN inside sees gross errors.
there is no other ways. to do that.

or if connected the CCFL tubes the monitor turns off
well the CCFL tubes are shorted. and if are, then the brain
was correct to shut it off or risk a fire.
see? it really is very smart.

Monitor goes black


You may have failed backlight inverter circuits, power supply, lamp assemblies. First place to look will be the power supply section.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Where Dell Flat screen 15" monitor has not been used for a period of time or on boot up the screen displays for a seond then goes black (although in a certain light you can see the icons and programs...


You most likely have a bad connection inside the unit. Specifically, there are a couple of "backlights" that provide the light that will pass thru the LCD panel. If you can open up the unit, with the screen facing up, there should be a small PC board on the right. Check the connections on that board. Be careful as there is high voltage there.
Keep us posted.

Blank Screen..Will not power off


The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
