Hi, I've got the same problem where the screen is switched on but it is almost completely black. I can see something is going on, but its too dark to even read anything on the scree. It sounds like you had the same problem.
Please let me know if you were able to fix it and what you did.

Re: hp 1730 - black screen .. or almost black
Your problem is in the inverter circuit. But the problem with these is normally easy to fix. It's the capacitors in the power supply board that need to be replaced rather then a direct repair to the inverter circuit.
If you have good electical knowledge then you will already know how to do this repair.
If not, then its best left to someone who does like your local TV repairman. The voltages inside LCD's go far above what you have comming from your power outlets in the house.
It should not cost a lot to have taken care of though by a professional. Call around and get a few rough quotes.

what i know is that monitors don't need drivers. if your monitor is new then i believe it is already windows 7 ready. what you need to do is check the VGA cable if it is damaged. try replacing a new one. Hope this helps.
it sounds like you have a small crack on your screen that has gotten worse over time, these black areas are where the lcd crystals aren't active anymore, unfortunately there isn't allot you can do apart from buy a new screen or put up with the black lines.
Does it do the same when it is hooked up to desk top PC?<br />

if after few seconds of display and then the while display turn black, this is the indication of failed capacitor on the LCD circuit board... you will need to have some technical skill to replace the capacitor.
If the screen is black (ie there isn't any backlight) then the fault maybe the inverter board that supplies high voltage to the CCFL lamp ot the CCFL lamp is faulty. For service, parts and DIY info. check out LCD Parts - use this link to their WEB site. www.lcdparts.net
The only problem that causes the power on and off is a bad power supply. Go onto http://www.ebay.com and search for the monitor (power supply). My dad's old LCD screen had a bad power supply, but I found my old printer power cable (HP PSC 750 All-in-One Printer), and the monitor turned on successfully. It's not a bad monitor, unless the PSU hookup is like the PC ATX/Baby-AT PSU cable, then it might be the issue. Monitors before 2004 or 2005 have the ones, like the HP PSC 750 uses. The monitor is either defective, or the power supply is dead.
p.s.: check the voltage, amp usage, etc. on the PSU for the monitor for better results.
Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.
Your problem is the power supply or the inverter on your board, you can replace it and it will be fixed. Easy Fix REALLY EASY FIX (inverter is what supplies power to your backlights. A lot of the times the reason a monitor goes black and the green power button is on, is because the backlights shut off. in most designs of the 1730 the inverter is embedded on the power supply. That is most often the case on this problem. Power supply/Inverter=Replace it and you will have a spanking new looking nice monitor working again. :)
