Sony vpl-dx140 "on/standby" light blinks green then the "lamp/cover" light blinks red three times. have replaced the bulb twice

SOURCE: Both the LAMP/COVER and FAN/TEMP indicator lights come on, not blinking

with both lights solid. according to the manual all it says is (there is an electrical failure inside the unit, please take to an authorized servicer). if you are able to do this yourself you will need the schematics and a voltmeter to start testing your voltages. your lamp is fine so dont waste your money replacing that anymore. if you would like the service manual send me an email to [email protected].

SOURCE: SOny VPL-EX1 turns on for a few minutes and then the Lamp /Cover LED and Power ON/Standby LED flashes.

hi,
your projectors lamp cover may be open. or there is some thing happened (may be contact problem) with the lamp cover open sensing switch. just open the door and close it. and then try again.
ok

Testimonial: "Thanks! And please tell me where is the lamp cover located."

Possible that the lamp is faulty -if the hours have elapsed- check the lamp holder, the fitments.
check also the filters, clean and reset.
Make sure the power supply Unit is not having any poor soldering or faulty components to reduce the voltage output to the lamp thus making it shut down..
