My laptop got bumped and now the screen is jumpy when it starts up. I suspect that it is something loose in the display. It's funny because the screen stops being jumpy after the laptop has been on for a while, but the initial jumpiness is getting worse with each restart. Should I take the lcd apart to see if something is loose? Are there any good tutorials out there about how to do this?

Step 1: If you are a frequent user of a notebook or netbook computer, then you likely use a touchpad to navigate your computer's on-screen cursor. However, there are a number of issues that can cause your cursor to seem jumpy or unresponsive. To find what is causing these issues, you can troubleshoot both your hardware and your operating system and find a solution to the problem.
Turn your computer off and then clean your touchpad. Dampen a clean cloth with some isopropyl (rubbing) alcohol and then pat the pad dry with a paper towel. Even a small stain or sticky spot can throw off your touchpad's sensitivity, so it is vital that the pad remain clean of all extraneous substances. Re-calibrate your touchpad. Go to the hardware section of the "Mouse" utility (in the Control Panel) and find the device settings. There should be an "Advanced Settings" or "Calibration" utility under this tab. Follow the prompts to calibrate your touchpad for maximum efficiency. Use manual troubleshooting wizard. If you suspect that your computer's software or drivers are at fault, run the manual troubleshooting wizard. Go to the "Mouse" utility (in the Control Panel) and then go to the "Hardware" tab. Select your touchpad and then click on the "Troubleshoot..." button. Follow the prompts to troubleshoot software issues that could make your touchpad jumpy. Reduce cursor speed. In the "Mouse" utility, go to "Pointer options" and reduce the speed. This will prevent the cursor from going too fast when you move your finger on the touchpad, which could be the source of the "jumpy" effect.
you need to adjust the refresh rate of the screen if it is a desktop monitor simply press the menu button on the monitor and go through thee adjust display settings or if it is a laptop go to the run bar and search for display settings
If it only does it running on battery power, try adjusting your power saver option. You may also want to run a program like Malwarebytes (free) to make sure it isn't some spyware causing the problem. http://www.malwarebytes.org/
sounds like a short in the lcd inverter they cost about 40 $ us but to install it will cost about 1 hr labor (60-80 $ at most shops) it might not have to be replaced if it only does it when bumped it just might be a loose connection
LCDs are not repairable, it is something you need to replace when defective. They also happen to be very very expensive to replace.
Is the screen cracked at all? cause sometimes when laptops get bumped, it is actually just the lcd cable inside the laptop that came a little loose and isn't making a full connection. If the screen isn't cracked or anything I would at least look into a possible loose cable first If you are not comfortable taking the laptop apart, I would bring it to a computer shop and have them take a look at it as some laptops can be complicated to open up. They shouldn't charge you more than about $40 to take a look at the lcd cable, they are normally pretty quick to get at. It is worth a shot as lcds typically range from $400 - $1000 and to have someone install it would be probably another $50-$100
If tapping the screen (on sides or back of case - not the screen itself
!) affects the display it is usually loose connections either at the
motherboard or behind the display where ribbon cable connects.
relatively easy repair for someone who can take apart a laptop but you
need the repair manual because there is a sequence that needs to be
