Question about Sony XL-2100U Projector Lamp for KF-42WE610, KF-50WE610, KF-60WE610, KDF-60XBR950, KDF-70XBR95
I hate to spend money replacing the lamp and that not be the problem. I have no sound, or picture.
Check lamp cooling fan for dust blockage. It is located inside the back cover (10 screws) and is in a horizontal position above the lamp from the rear side. This is an air intake fan. The cooling fan you can see on the back panel is the exhaust fan that sucks out the hot air. A clue is hot or melt marks around the lamp housing.
If the lamp cooling fan is blocked you'll get red flashing diagnostics light flashing. It's trying to say clean me so I can keep the new lamp cool. Sony is silent on this in it's manuals. I'm guessing they don't care because is causes lot's of parts business!
I learned all this after replacement lamp burnt out after 1 week. My lamp cooling intake fan was found blocked and wasn't spinning. I saw the exhaust fan working and thought all was ok, not even knowing there were more fans. Some models even have another fan inside the optics blocker. I didn't take mine apart that far.
