Is there a way to "refresh" a really old panel?

Hey guys I purchased some pretty old monitors HP LP2465 for relatively cheap and one has 8000 lamp hours while the other has 24000 lamp hours. I was wondering is there a program or anything that will refresh these panels. I read there was a hardware device that does this but it seemed like maybe all it did was cycle colors on the screen which I can do with Dead Pixel Tester. Should I cycle colors on the screen for an hour or two? Will that do anything?
