I have an HP 1955 LCD monitor, which would flash once on power on, and then go black and nothing showing.

Its a problem with the inverter. check the 4 transistors, C5707 near the connectors for the backlight. If none are defective, look for the PF751 FUSE. It sure to be busted.You can replace that with another 3A fuse. Remember, you should only replace the fuse if you are certain there are no busted transistors in the inverter board. Otherwise, you now have a refurbished Benq Monitor

Possibly either the backlight lamp or its associated power supply has failed. Power buttons (mostly LEDs) have constant availability of low voltage (for some other circuits too) otherwise they wouldn't 'wake up' on command from a computer as some do.
The blackout could also be due to a failed main power supply so the incoming video is no longer being processed. 

SOURCE: LCD monitor no display - flashing power button

hello, my best guess is that the refresh rate is set for a crt monitor. hook your old one back up, if you can. and change it to 60 hertz or 70hertz. go 2 display properties then settings then advanced; then monitor. set the refresh rate as i said and turn off the computer, hook the new one back, and you should be good to go. good luck! and please rate this solution. if you need further assistance, reply

Its a problem with the monitors power supply ,you will have to take it to an HP support center and ask for a quote.
if it's under warranty then you won't pay to fix it.

SOURCE: HP w2007 monitor will not turn on.

The only troubleshooting step I can offer here, is unplug it, and press the power button down for about 15-20 seconds, to flush any trickle power remaining in the unit. Then plug it back in, hook it up and try turning it on again. If this solves it, great! If it doesn't though, then I would check either with HP directly or with your place of purchase to see if your issue can be covered under limited/extended warranty. If you are out of warranty though, LCD repairs tend to jump pretty high, and usually end up being more than what the monitor is worth, so it may be more economical to replace it at that stage.
