Hi Guys, The FAN that cools my BULB has taken a dump on my Sony KDS-50A2000 and I need the part# for a Sony replacement fan. I need this ASAP because my Optical Block is also bad and I only have 25 days left on my 2 year Opictal Block warranty and need to replace the fan before they come look at it. Any suggestions on places to buy the fan cheap would also help too. The fan I took out has "SFF21C" printed on it but I don't think that's the proper part # Thanks !
