    EDIT : This question was wrongly marked as a duplicate (see comments) and has thus got bad reputation. I have still not been able to find any solution, answers will be appreciated.

    Unfortunately some water got into my lcd screen creating weird dim patches against the bright back light. only the screen seems to be affected, not anything else.

    I am thinking of keeping it in the sun so that water could evaporate, or maybe using a hair dryer. What adverse effects may this have on my LCD screen?

    EDIT2 : I tried other options to make the water go away, none of them worked. Seems like heat is the only solution, but I'd still like to know of any adverse effects so that I don't damage it further.

    Rather than a hair drier blowing hot air why not blow unheated air? I do that to my coffee maker's LCD display when it gets water in it. A window fan or desktop fan.

    Laptop screen sometimes doesn't work. Is it the LCD cable?
  • Mike

    I have a laptop where the screen sometimes works and sometimes doesn't. One of the hinges is broken, putting stress on the LCD cable. I have taken it apart now to replace the hinge.

    While it is apart do you think that the LCD cable is bad or maybe just loose from the broken hinge? I guess the bottom line is: should I replace the cable while I have it apart or just make sure the connections are secure when I put it back together? Could the inverter also have anything to do with this?

    I am guessing this is probably a ribbon cable? If not please put more detail in.

    The cable(s) would likely be stressed by the bad hinge, but that doesn't mean the LCD itself is not bad. If you can try and spot-check to see if certain positions work better than others (if you're brave enough to turn it on with the case open like that) that could tell you if the cable is bad. I would likely just try and reseat the cable or cables and put it back together, hoping for the best.

    Also, of course the inverter could be a problem as well. Just as in a desktop, a problem could be the power supply, motherboard, sound card, memory, graphics card, etc. Everything and anything would likely need to be checked. Unfortunately, without another of the exact same model of laptop its hard to troubleshoot.
