    thanks for the reply.

    I had already tried the problem solver from hp and it points to a bad panel or hardware that drives the panel is bad.

    It is not a pc issue as I have conected it to another pc and also trid both DVI and analogue cables with the same results. I have opened it up and re-soldered a few suspect joints but I need steering in the right direction, ie power inverter or screen driver board etc. later I will try and test components with a volt meter to see if I can find anything that way.

    I dont know much about PCB's but I will have a go as repairs will cost about £150 i can get a new one for less. it may be something that costs a few pence to replace.

    Also the monitor failed whilst in use, there were no system changes.

What was the last thing you were able to do with it? Have you made any changes to the monitor's or your computer's settings and configuration before the problem came?

Firstly, assess whether the problem lies with the monitor or you pc. It's simple actually. Plug the monitor into another PC, or a DVD player or any other device that would accept the data connection to you PC. If the monitor works on other systems, then the problem lies with your PC. If this is the case, post here again if you need help to solve this.

If the monitor doesn't work, then the case is most probably that the internal chipset of the monitor itself has been damaged or isn't working anymore. The usual causes for this are moisture getting in the monitor, old age of the device, dropping/bumping/breaking/etc of the monitor. Best to have it sent to your dealer or the nearest qualified service center.

Hi I have a problem of black screen with my hp pavilion dv400. Wheen I start my computer I can windows logo on the screen but just 1 or 2 second and the screen go black. But when I connect my computer...

Your laptop is probably outputting the video signal to the wrong monitor. When the screen goes black, try pressing the function key to switch the video back to the laptop screen. Refer to your laptop's manual on what key to press. Usually it is the Fn key and F4 at the same time for HP laptops.

Monitor goes into power saving mode about 6 sec after powering it up not enough time to get to the menu settings

A monitor switches to power saving mode when it is not receiving a signal from the computer. Check the lead isnt loose & if you have removed it recently, check you havent bent any of the pins.

This can happen if the minus button which happens to also be the auto image-adjust button is effectively grounded due to some internal fault or
if the switch itself has got jammed internally. In this case, if video signal is present, the motitor reproduces the image but continuously displays "adjusting" as osd message. If video signal is missing, the monitor cycles through solid colors in the black, red, green, blue, white sequence. I think this is part of the hp f1532 design to help the service
engineer( though I have not found any reference to it in official documentation yet). In this special case( minus button grounded), the
menu button is ignored by the monitor.
