there are 3 capacitor in the power supply section on the circuit board, you will have to change all 3 capacitors the value of the 3 capacitor are 1000uf/10v and all 3 are soldered at one location, you need not search for those capacitors, if you see the component side of the board you will find those 3 capacitors either difused or burnt out.

Check this price on E-bay. That's how I always do it.If you go through HP, you will probably be paying over US$100

It may have unstable DC problem due to bad caps, see pictures here:

This model is also known to have bad lamp assemblies. I would inspect the power supply first.

Hello,
Reading the symptoms there might be some things:
1. Incorrect voltage by the power supply unit to the mainboard and the lamp(s). 2. The lamp(s) used for backlighting the lcd matrix. If you have another 17" matrix (the lamps are integrated inside) you can switch to check if the problem will be fixed. 3. CPU fail
If you are a technician working in a computer repair company there is a chance to get same model and get 1 working of 2 failed monitor, otherwise buying a new one will be cheaper than the repairing in a service.
Hope this helps Alex

Hi there.

It could be a connection problem between your monitor and your PC.

On the back of the monitor, you will see a VGA cable (usually blue color), it looks something like this:

Make sure that this cable is connected properly to your monitor and the other end to your computer.
NOTE: Those 2 round things are its screws, you have to turn them to remove the cable and turn them again from opposite direction to hold the cable in place.

Thank you. Let me know questions.

It can have bad DC filter caps, bad lamp assembly as shown. You need to open it up and troubleshoot the problem.

Try to look for the monitor-settings.

Reset the settings, or set it to VGA.

It can be as simple as bad caps, or worst case will be bad lamp assembly.

The maximum-resolution supported by some video-cards can be less than 1280*1024.
You need to install a "better" video-card into your computer.

You need to check the video cable at bothe ends, no bent pins? Video cabel seated properly?
Does it do the same when use it with another PC? We need to make sure before we have to open up the monitor.
