    I checked the connection and it seems to be ok. if I have the laptop screen opened all the way it works to a degree. if you start to close it the screen goes crazy and goes white completely. If I press on the left side of the keyboard it can fix the issue temp or if i push on the back of the lcd it fixes it temporaily

    It really smells like either a connection issue. If it was an issue with an IC, then it wouldn't respond to the physical tests. Have you taken the notebook apart as described in that manual I gave you link to?

I have the same model of laptop; and not had a problem swapping with other X-series screens taken from Compaq/HP and IBM laptops. (My laptop is a bit 'incident' prone, and is +70% by weight replacement parts.)

As for assembly/disassembly and a (very) partial replacement part list, HP publishes the Service Manual(pdf) online.

Also, if you have a model with an aluminum heat sink take this opportunity to remove the sliver solder attaching the aluminum/magnesium heatspreader, and silver paste-- (someone in QC failed highschool chemistry, remember the galvanic series ?). A hard eraser will remove the worst of the rust, use an odd bit of pottery if you need a mirror finish. I then reccomend using a good latex-ceramic paste, your laptop will then avoid the spontaneous shutdown issue.

Hi there.
It sounds like you may have a loose inverter cable or the ribbon cable behind the screen is loose.
Is the machine in warranty? I

U may have a dead board. They average $285 plus labor. A shop should be able to test it on a volt meter see if the power grid is burnt for around $35. then u will know what ur in for. If its a bad board just replace the laptop I wouldnt repair that problem on an older laptop.

White Screen Compaq Presario CQ60


Regarding ; White screen , I flipped my notebook over and removed the power source(s) , power cord and battery. I then removed the three screws in the battery cavity and the two outside corner screws to gain access to the connection for the LCD and found a loose connection. It seems that the wire that connects to the screen was being moved every time I opened and closed my computer. So very glad to find that bulb and inverter board was not bad. Prior to this , I did try external monitor and found that all was okay as far as operation of start-up.

Laptop screen blank all white


Either your LCD Video Cable is not plugged in snuggly or the monitor is slowly going bad. The fact that you can see the images on an external monitors says your Video Graphics Card is working fine. You'll need to disassemble the laptop to get to the cables. Get a quote from your local computer shops, then try the guys at: http://www.generalsystemsconsulting.com Most times they will fix it and ship it back by Fedex or UPS cheaper than any quote you obtained including the shipping.

Screen gets blurred and comes back after applying pressure on LCD


from your description, it appeas to be an issue with the LCD since applying pressure has effect on it. I would advise to check with compaq for warranty repairs if you still have one active. The LCD may have to be replaced for this situation. You can try to use an external monitor to check if the video controller actually works properly

Laptop screen turns white


You can put your laptop on top of a icepack, cause your Graphics card is probably getting to hot. Thats why your screen turns white(probably only when gaming).
It is likely one of your fans is broken
