If you have access to a desk top computer monitor, plug it into the side port on the laptop. (usually a blue port) and see if you have a video signal. If the Desk Top Monitor functions, and the Laptop is black; your Laptop screen is NG.

Follow these steps to avoid overheating:
-Don't use your laptop in full sunlight for extended periods
-Don't leave your laptop in a closed car on a sunny day
-Don't place your laptop on or near extreme heat sources, such as radiators, hot air vents
-Turn off your laptop before putting it in your carry bag
-Turn off your laptop when not in use for a long period
-Work on an even surface as much as possible ?€" not your lap!
-Clean the air vents in your laptop regularly by using a can of compressed air
-Get more space under your computer by propping it up on something when it's on a desk
-Consider purchasing a laptop cooling pad
-Consider purchasing an external fan

To clean your laptop's cooling system follow these steps:
-Shut down the laptop ie do not leave it suspended, sleeping or hibernating.
-Unplug all cables from the unit and remove the battery pack
-Get a can of compressed air and blow it into all vents around your computer - this should clear out any dust and hair.
-Do Not use a vacuum cleaner.

The buzzing sound could be from what they call a Ground Loop.
This is cause by plugging in Hi Fi and computer devices etc. into different mains power sockets.
The way around this is to use a power board and connect all your devices into the power board and plug the power board into a single power socket.

yes. depending on pc type.
on a laptop, connect a 3.5mm jack to headphone socket and rca to aux in.
on a desk top connect 3.5mm jack to audio out(green) to rca to aux in

Easy! You need a wireless router. My recommendation is Linksys wireless-G (or wireless-N if the laptop supports it). Linksys routers are easy to configure and very durable. It'll run you $50-60 at any computer store (Walmart even has them)

Best of luck, and make sure you rate users who offer their time & expertise to you for free :)

Ok thats easy just buy an s-video to rca cable and plug it into the dvd-vcr combo in the av in and then turn the vcr on to av 1 2 or 3 what ever you pluged it into then when that is all turned on and pluged in then you plug it into your laptop and wait it should switch over automaticly

Does the green light on the charger turn orange when you plug it in? Because it might have been that you didn't actually charge it. The metal ring around the charger tip sometimes gets bent so that it doesn't make good contact. If you aren't getting a constant green or orange light when you plug it in, you might not be charging it at all.

That would be the easy fix. The real problem is probably much greater, because you probably know how to charge your laptop. The laptop doesn't need a battery to run, so if it doesn't start up while plugged in, you have an additional problem.

write back if you find that the simple things didn't work and you need more help figuring out a specific fix.

This tv make a lot loose connections. If you re solder and nothing change, check fly back area's is OK?... Look around convergence board for liquid coolant ( some times CTR liquid coolant projection splitter , becarfull, Liquid is danger!!) Wash yous hands and clean chassis with acetone.
