The projector powers on, but the lamp does not project since there is a service required lamp flashing. The last time this projector was working, the lamp worked as well.

Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

Replaced the projection lamp again.Sony projection lamp more expensive,but last longer too.Genaric projection lamp brand last about 1 1/2 max.U hear clickinng sound too,when LED light flashes?Mean the Ballast board also dead,require changing too.The Ballast board help to ignite the projection lamp.

First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.

is the led lit on the top of the projector? what colors?

green is ok.

red flashing in sequence:
2 times- lamp hours exceed 200 hrs. replace lamp.
3 times- lamp failure. replace lamp.
4 times- fans not working. remove obstruction or replace fan.
5 times- temp too high. clean thoroughly.
solid red- undiagnosed error by projector. possible power supply or ballast.

also make sure the lamp door switch is working.

lamp duration

go into the menu and the service or settings option. reset the settings to factory default. also, it does not do hd. make sure the resolution matches.

sounds like a flaky power supply or lamp ballast

The flashing red indicates that either the fileter cover or the lamp cover is not installed correctly. If both are installed properly and secured, the unit will require service.

Thats the projector telling you that you need to replace the lamp. Lamps usually lasts for about 2000 hours so if you had it for a while you may need to replace it.

www.froogle.com and enter your make and model or go to www.projectorcentral.com and find a few retailers in the US that sells lamps.

good luck

How many times does the light flash?
