Question about HP TouchSmart IQ770 PC Desktop

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

    First place I looked is the manuals.

    What I need is a "cookbook" that takes you through steps to remove the MB. Something that HP is NOT going to put in their manuals; that would defeat the whole charge you a bunch of cash for repairs thing.

    Everything is very compacted into the case and you need to know what to disassemble first or you'll end up breaking a piece of plastic or connector!! (learned that already @$&*$@).

Check out this web-site that was set up for "Touchsmart" owners; there are many discussions on this very topic there and one person has successfully fixed their IQ770 with a black monitor problem who has posted.

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.

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.
