Ok i switched my tv on this morning and noticed that the top right hand corner of my screen has a burn mark on it, this is from when the kids where watching the Boomerang channel on sky which when viewed there is an arrow pointing to a circle on it. This has now left a burn mark on my tv is there any way of removing this? and also is there any way of cleaning the back of the screen because there are a few marks on it from something that has been inside the tv.
When i was watching my tv a few months back i saw a small bug crawling across the screen, i went to go and take it off but to my suprise it was on the inside of the screen

it must of gotten through the small vents on the side of my tv so its probably still in there now dead...But if there is any advice for my burnt screen i would be very glad to hear it
