KDF-E50A10 Fan Noise

I purchased this set in late 2005. Since then, it has run 14 hours a day with no problems. Yesterday, the fan started making a noise. The noise sounds like it is a fan bearing going bad. Can I replace the fan? Where do I get one from? I assume, due to the amount of use, that this is a typical problem, or am I way off base? Thanks

    Thanks man. Just got home from work and vacuumed the back and turned it on. No noise as of 15 minutes in. I believe the fan that cools the main bulb was the one making the noise. If it starts again I will localize and post the info. Thanks for the help.

    After 30 minutes of use the noise started again. It is the fan that cools the bulb. I can see the bulb through the fan. I blew canned air into the fan and it quieted it down for about 5 minutes. I need to know the part number and if I can change the fan without too much trouble.

Looked your set up and this model DOES NOT have the famous color wheel in it so if very well could be a fan, question is there are three. All differant sizes and have differant part numbers so you will have to find out which one and get back to us on its location.

Standby Light blinks 6 times, no picture no sound.

Have you tried a lamp?? Most common problem with these Sony projo LCD sets. If ma have a "fan stop" issue--that is preventing the set from coming up due to one or more fans not running, probably due to dust. One other possible problem--if the set is totally dead--with no fans running or such, is a bad thermal cutoff , near the lamp, or possibly a lamp door switch not making good closure.

There are more than 1 fan in the set; however, the last one to turn off is the lamp fan. The lamp fan keeps your lamp cool and helps extend the life of your projection bulb.

You could either replace the fan, or remove the fan from the set and give it a good cleaning (that's all it might need). However, be aware, fans that go bad in these sets will start to shut down your tv and decrease the life of your lamp. Be on the lookout for intermittent or sudden shutdowns, as those can definitely indicate a bad fan.

Sony KDF-E50A10 No Picture

4 times blink error shows that any FAN is not running in TV as there are 4 fans in this TV.
Please check fan connectors and make sure all are plugged securely.

I think, Lamp compartment locates at rear side near cooling fan. Open the cover and pull out the lamp. Please Don't pull HOT lamp.
