Take Apart IQ770

Is there ANY place I can find a procedure to take apart my HP IQ770 touchscreen? I have a video card problem (screen gets power but nothing shows up) and I'd like to replace the MB since it is integrated. It appears that it is a matter of some screws, but I can't seem to get it done. Any help would be appreciated I have nothing but color lines on the screen when the computer powers up. I believe I need to replace the graphics card but I can't figure out how to get to it to replace it. I need step-by-step disassembly instructions and can't find them anywhere. The manuals from HP are of no help. Please HELP!!! Phil

    Thanks, but I have been to all of these sites and I have all these manuals. NONE show you how to tear the unit down completely as to remove the MB and tuner card. I have taken the back and rear panels off but cannot get to the MB. Thanks for any further help... Omni

If you had got any new hardware perhaps Speakers? try and make sure the speakers are not very close to the screen.Because the electromagnetic waves affect the monitor.

If not then adjust the screen resolution.Hope your problem will be solved

No Video; (hp IQ770) You can hear it booting Properly but nothing shows on the screen. (either the monitor or video card has gone bad) How can I test to see which is the problem?


does this unit have an external monitor connector? if it does you can use another monitor to check t he output of the video card.

other than that....I think you are headed for a repair bay somewhere.

Touchscreens are EXPENSIVE and difficult to replace. It's not even just soldering. I'd look up any warranties you have on the laptop and see if you can get it fixed for free. But first - try a few things. I know that for some people this may sound like baby talk, but it is the proper procedure to go through.
1. Make sure that the wiring is firmly and correctly plugged in. Your cat may have knocked the graphics port loose by traveling behind the PC.
2. Check and see if you can get another monitor to work on it. Most modern LCD/LED/Plasma televisions have a port you can use.

If that doesn't work, your monitor is actually fine, and you'll probably need a new graphics card. Again, check all warranties, consult your manual, and see if your computer/monitor manufacturer will fix it free of charge under the warranty.

HOW DO I GET TO THE VIDEO CARD ON A IQ770


The video is "ON board" which means it is built onto the main board and can not be replaced with out a new mother or main board. If you have an PCI slot or PCIE you can add another video card and use that for your primary display.
