I found an insect had made a home inside my lcd screen which was really getting on my nerves. Since the warranty had already passed, I opened the display, unplugged it from the laptop and found that I could not get the insect out without taking the display apart far more than I felt comfortable doing. I plugged it back in, closed it up and resolved to live with the pest inhabiting my screen.
The screen worked briefly thereafter and then stopped functioning properly. Each time I turn on the laptop is different. Sometimes I get a black screen (with or without a blinking cursor in the upper left),vertical multicolored lines, split screen half blue half white, and the windows load screen (slightly garbled). The furthest it will ever go is to a screen where its fuzzy blue and yellow pixels with a clear mouse pointer displaying. I have also tried getting it to work in safe mode with no success.
Maybe the lcd cable just came loose but I'm worried that it might have something to do with the inverter, or even the graphics chip. Maybe there is a way to reset the lcd display to reinitialize itself when I power up?
In any case, I now know better than to wish for an insect free lcd.

Re: LCD Display behaving badly
It sounds like the ribbon connector or flexible connector is not seated quite right. I would open up the unit again and carefully inspect this or any other cable that you had unplugged. Reseat these properly and power it up again.
These cables can be very easy to damage if not replaced properly. Take special care.

An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source. A Backlight can be a CCFL, (Or two of them), or a series of LED's. (Light Emitting Diode)
A CCFL is a Cold Cathode Fluorescent Lamp. Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
Average thickness of the bulb is 2mm. That is a little larger than 1/16th of an Inch. Average length is almost as long as the LCD screen is in height. (Yes. They have Mercury inside, just like their larger 'cousins')
A screen Inverter is used to convert the power from the laptop, for the LCD screen, and Backlight.
Laptops that use LED's for backlighting, do Not always use a screen Inverter. It seems older laptops using LED's may, newer laptops using LED backlighting generally does not.
You need to diagnose.
The problem will be the;
A) Video Cable. Or B) Inside the Display Assembly
Inside the Display Assembly: Either the screen Inverter, IF used; or the LCD screen itself.
I don't believe it to be the graphics chipset, but this is a diagnostic flowchart we will be following, and there IS NO guessing. The graphics chipset is checked too.
Post in a Comment as to the laptop manufacturer name, and model number. The model number can be found on the bottom of the laptop.
This way if I have access to the Service Manual, I can post a link to it for you, and perhaps some pictorial guidance too. Plus step by step guidance from me.
[May just be a loose connection of Video Cable TO motherboard, or back of LCD screen. May be a damaged Video Cable. May be a bad screen Inverter. All these check out it is then a bad LCD screen ]
Connect an external monitor, to see if you can read the text on that screen. Is your computer still under warranty? It could be either the LCD screen or the computer's video-card that are "behaving badly".
That really sounds like the LCD screen is cracked. The front will not feel cracked because of a clear plastic cover sheet but behind it is the LCD panel. The liquid you see is part of the screen leaking. The LCD actually means "liquid crystal display" and that is what you are seeing leak out between the cracks in the panel. You will need to have the panel replaced to clear the problem. You can get the panels from Ebay if you want to do the repair yourself. This type of repair is not covered under the Acer warranty. If you have any questions just use the email address below.
Please try to connect the laptop to a different monitor or display output like LCD or a projector, in case u find the clear images then the issue is with your LCD otherwise the issue is with your video card. The replacement of the LCD depends on the type of warranty you have.
Sounds like either the LCD or the inverter to the LCD is going bad you on. After it heats up thats when the problem starts. If your laptop is under warranty I would call HP Tech Support and let them troubleshoot with you over the phone either way they will probably replace the LCD and inverter.
I had a similar problem with a flat screen lcd for my desktop comp, and it turned out that I needed a new screen if i wanted to get rid of it, but it doesnt really cause much of a problem, so i didnt bother replacing it. If your laptop is still under warranty, (i dont know how long your warranty lasts) I'd look into getting it replaced if it really bothers you. But yes, its definitly the screen.
