I have a similar problem to one posted a few months ago - flashing LED on the power button, except the monitor does come on after a couple of minutes and the LED stops flashing. bdmrtn said to the other...


Look real close at the solder joints on the inverter transformer pins, and the transitors. What usually happen is that the cold solder joints will mess up the bias on the transistors or causes arcing and that will take out the transistors, you need good magnifier glass to see, you will see ring/cracking around the component's leads.

It will get to the point that the transistors 2sc5707/5706, and also still should look for bad caps.

Hp dv1000 laptop, just replaced lcd inverter, still no back light. You can see the screen is working just no back light. The led is on on the inverter.


You need to verify that you do have 9~12vdc feeding the inverter board. Did you see the backlight turn on for a second? Worst case will be bad lamp.

Screen going black, green LED staying on


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. :)

BenQ FP767 17" LCD Monitor Problem - Power LED Blinks


Look for small power transistors 2SC5707 near yellow invertor transformers which go to backlight connectors.
But if problem is blinking power LED powersupply capacitors maybe an issue,check visualy and/or replacement.
Also fuse that maybe blown is not glass fuse near mains socket,It is semiconductor black or yellow colour labeled PFxxx near heatsinks of power supply secondary.

Please rate the solution and provide feedback.

Inverter problem , prefer to repair the board not buy new parts


repairing lcd inverter is like repairing a hv circuit used for strobe lights. try to check first all electrolytic capacitors, then loose board solder, also occularly check both ccfl bulbs for breakage and burnt marks.. best is if you can download schematic diagram for it so that you may check also all semiconductors on the board.

Replacing Inverter Board


I did some poking around and only found a few places that sold inverter boards for this monitor. Ebay has one that sells for about $80: http://cgi.ebay.com/Backlight-Inverter-for-Gateway-FPD1930-LCD-Monitor_W0QQitemZ160070918225QQcategoryZ174QQrdZ1QQssPageNameZWINQ3aPOST0Q3aRECOQ3aBINQQcmdZViewItem I wasn't able to find any specific instructions posted, however, taking a typical LCD panel apart and replacing the board shouldn't be too difficult. The only hard part is not getting shocked, which is why this is not a job for the typical user. Anyway to disassemble the typical LCD you remove the pedestal from the back of the LCD then remove the screws around the back of the LCD, remove the back and look for the inverter board. Typically it is covered with a metal shield; again the hard part is knowing how to correctly handle the parts. Considering you can buy a new 17" LCD for $120 to $150 (and has a 1 year warranty) you might want to consider investing in a new monitor instead. If you have any other questions let us know, otherwise please don?t forget to rate this posting.
