SOURCE: projector automatically shuts off immediately after turning it on

If your comfortable w/surface mount troubleshooting and soldering, download the service manual from elsewhere online. Part of the troubleshooting tree for this type of problem is to check the surface mount fuses on the underside on the Main PWB (schematic page 1/8). On mine, the 12V surface mount fuse, F3004 (2.3A) was open (quadrant C1 on the schematic). Replaced it, reassembled the projector (3 interlocks don't 'cha know) and it came up just fine.

Hello toma_leonard,

First check your lamp to make sure it is seated properly in the socket.
Then check all of your interlocks (see your manual for locations), these are usually located on any hatches or doors that allow access to the lamp and or fan area. Once you check your interlocks make sure the filter and fan area is clear of dust, (some projectors have air flow sensors), and the recheck the interlocks. Once this is done , If the interlocks are not broken, or the lamp fuse blown, the projector should be working. If not it is the lamp that needs changing.

I know this may be expensive, however these lamps do go bad, as much as we wish they would not.

If you still feel it is not the lamp, have a technician check the voltage levels to the lamp and the levels of the control board circuitry.

I hope this helps,

Thank you,

SOURCE: alternating power and lamp status lights

...replace the lamp. The lamp is most likely WAYYYYY past its prime so I suggest starting there. Sometimes even if you had just replaced the lamp the new lamp could've blown. When there is no signal running through the lamp circuit there is no signal to the display sensor, which means no image.

hope this helps!

Projectors shut off when they overheat. They overheat when air does not move through the projector cooling it. This happens when the fans are not working or air filters/vents are not working.
Check to see whether the fans are working. If they are working, open the cover and see whether air filters/vents are covered with dust. If so clean them.

green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

Projector screen turns off after 10-20 seconds


Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
