Question about HP Pavilion F1703 17" LCD Monitor
I own a 17'' inch Packard Bell TFT monitor. Everything worked fine until now.
The problem is that when I plug in the power cord, the blue power on/off led keeps blinking continuously very fast. There is also nothing comming up on the screen. It keeps black all the time.
It's a defect in the monitor that I would like to fix maybe.
Does anyone has any suggestions for this problem?

Hi Rahni, It's a very common problem. LCD's use four small Cold Compact Fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino

it seems that youre monitor has a dry solder problem, try tapping it if the picture resumes to normal for a while than get it resoldered from a technician. if it soesnot solve problem than look out for a burnt resistance.

A blinking blue light indiactes that your power-inverter board is not
putting out what it should. It needs an overhaul which may be a simple
as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

Unplugging the power cord repeatedly is not a good idea! I hope this helps: 1- After you get a picture, go to "Device manager" (Click on Start-Programs-settings-device manager) and make sure that there is not question or an exclamation mark next to Monitors. If that is the case you might need to reinstall the driver! 2- Make sure that your video card is not faulty by hooking up a different monitor and see if it is working ok. If you still have the same problem, then you need to replace the video card. 3- Check all cables and power cords and make sure that there's good connectivity on all ends (before powering up the machine) and that there are no nicks or cuts. If possible try replacing the monitor's data cable as well. Good luck
