HP L1906 picture does not re-appear immediatly, after being away from it for a while. The green light flashes for about 2 min before the screen re-appears.


It may have dying power supply due to bad DC filter caps just like the HP as shown in my albums.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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.

I fixed my broken HP L1906! Couple new capacitors in power supply board and it could be powered up. Green led (for power) is on, monitor begin to circle 18 times - red, blue, green white horizontal...


SCREEN DAY.
BUT NO PHOTO POSTED, worth 1000 words each,
can be lots of things ,
bad power supply, something shorted. caps but in backwards.
+ to + and - to - works only. or the short. every time.
there is no schematic,
leaving what?, guessing ? and buying used parts on ebay
expensive to do that.
i presume the OSD button is dead ,right?

the power button tells you its a hard failure, it did.

The L19xxxx has CCFL back lamps, most did.
so seems they work ok , to see color takes that working.
but power is first ,that mean not just 5v.

Look for bad caps with leaking/bulging tops like all the failed monitors as shown in my albums here:

My power light just blink green. screen remain black


Three possibilities: bad caps in the power supply, bad inverter circuits, or bad lamps. You need to open it up and inspect the caps first. Post back what you see so we guide you more. See example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Hp l1906 LCD MONITOR SCREEN WONT DISPLAY. power lcd green light keep blinking. Any solution? thx


It is possible that the video card in cpu is bad, try hooking up another monitor to the cpu (computer) if you have one that will let you know if it is the monitor or the computer video card, Could be as simple as the driver is missing.

HP L1906 lcd monitors won't display anything


Yes you got badcaps!!! www.badcaps.net examples of what they are and what they can do and this is one of them. U/You can change out these caps and see if it fires back up again.

Even bulging caps are still issues I just fixed a emac with bulging caps as the emac would freeze not when i put in the new caps the ****** is doing great!!!! I would suggest you do the same.
