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

Hello , the problem is usually the Power Board . Requiring a technician to fix it

1,is the power line is OK?
2,if the power line is ok, it means that the projector is defective
3,the mainboard or main power of the projector is defective?

Hello,

Try resetting all the connections.

You can reset the "Filter Time" on your projector and it will clear this error out of the system.

1) Clean Filter
2) Turn the power on
3) Hit the Menu button
4) Once the menu appears choose "Options"
5) Choose "Filter Time"
7) While the time is displayed hold the "Reset" button on the remote for 3 seconds
8) The "Reset" menu will pop-up and choose reset.

That should take care of it.

not a solution just wondering what the problem was

Check your cable...you are missing one of the primary colors. you could have a bent/broken pin on either the projector port or the cable or laptop port. this would be the VGA connection.

reset the settings to factory default and check the lamp for bulges, black spots, fogging or flaking, and replace as necessary. if not better, you may have a fried polarizer on one of the lcd panels due to excessive dust and heat. that will need to be replaced, buy you may have to replace the entire optical engine, as many manufacturers don't sell the individual parts.

Yes please.
You can connect it either thru the RCA Composite output(yellow) of your DVD or thru the S-Video or even thru the component out(YPbPR) connections. In the component out you would require three RCA cables and would give you the best possible picture.
