Samsung 37 inch with image retention problem

We've got a LE37R8 that we got towards the end of 2007.
Over the last week it's been having image retention problems.
This basically means if a logo appears on the screen for a couple of seconds and you go onto a white background you can still see the trace outline of the logo left behind and the logo can stay there for 10 minutes before it has gradually faded away to then be replaced by the trace of some other crap if I use the sky guide I can see outlines of the guide on the screen.
Text is especially bad I left it paused with the limitless logo on the screen just to see and you could see limitless burnt into the screen for a few minutes after I'd unpaused.
The screen burn is always temporary and I've seen it been called image retention when trying to read up about it.
Anyway is there anyway of fixing it?
The screen is perfectly clear otherwise.
Don't want to throw away our tv because of something that isn't always that noticeable.
It is a pain in the ass though so I'd like to fix it if possible.
Anyone any suggestions?
