ViewSonic LiteBird PJ875

Most likely

Clean the unit and make sure no dust is clogging the air to the lamp.

sounds like a bad bulb

projectors get a resistance reading from the bulb and if it doesnt get right value it will give you the double red lights

only other thing it could be is if the fans in projector are not turning on

call viewsonic and tell them issue and make them resolve issue

or

if unit is only 2 weeks old bring it back to store and get replacement or call viewsonic and get them to send you replacement unit - it is too new to mess with it yourself and take chance on voiding warranty

reset the timer.

If totally dead look at the circuit board at parts after on/off switch. Is there a fuse in one of those immediate lines? Is it open (happens for no reason at times)? And the diodes - any cracked or burnt? Nothing is working so it has to be something all these items have in common.
See if you can get a hold of a schematic for unit from manufacturer. Or get a service manual through Google.

kdbooks, CCFL lamps could be weak (tired) or switch-mode-power-supply"/"ccfl inverter-supply" may need rebuild. Read my fixya profile for a while. Reading is free. Your ccfl back-lit lcd display is no different than any other brand in it's basic design and operation!!! Follow all links found on fixya. See how lcd displays are repaired to determine if you are capable of DIY repair to your Black or Blank n Black screen unit!!! Read the older (pg.15 and up) and you will understand all your options. Visit youtube. If unit out of warranty, then you will need to make decision on contracting out the needed work or if you will DIY repair!! Good luck on your quest. 12fixlouie

I have the same problem as posted too, ordered 3 new lamps and they all still do the same thing. I`m starting to think its the projector that has a problem. Anyone got a solution other then keep buying new lamps and try getting it to work... I mean, after 3, how bad lucky can you be that they are all bad lamps...

My solution sounds dumb, I had the same issue. Took the lamp cover off the bottom. The screws were loose holding in the lamp. Maybe they heat and expand and eventually work their way out and the lamp doesn't make good contact. Just tightened mine up, the unit would power off after 45 minutes prior. Been on now for 5 hours, no trouble.

Company said it was defective. Sent back for exchange.

I have the same problem before. I found a replacement fan. A computer chassis fan works perfect. It should be 60mmx60mm - plenty in E-bay for about $5.00. Very easy to open the unit to replace the fan. It has 2 fans in a rubber housing. Check which one need replacement.
