Once opened the U can refill the fluid yourself. Surprisingly, you can fill it with distilled water. I had the same problem & after extensive search to findout what type of fluid it uses, I was advised to use distilled water as a substitute. It worked fine.

(REVISED EMAIL) CAN I REMOVE THE PROJECTION TUBES MYSELF AND TAKE THEM TO THE SHOP TO BE RE-FILLED OR IS IT BEST TO TAKE THE TELEVISION TO THE SHOP TO HAVE THE FUILDS LEVEL RE-FILLED.
