Question about InFocus ScreenPlay 7200 Multimedia Projector

7210 premature shutdown

My 7210 projector prematurely shuts down after an indeterminate length of time. The green light is on (not blinking) and the fan is running, but the lamp just goes off. Sometimes it will work all evening and sometimes shuts down after less than 30 mins. The unit was sent back to the manufacturers in the Netherlands and it was returned stating that it was not faulting. They had cleaned dust out of the unit and downloaded a firmware upgrade. I have had it for just 18 months and the lamp hours are 1910. The unit will not even display its own logo or menu, it just goes out. If I switch it off and back on again, it usually works for a while, but you never know for how long. Is this a known problem or do you have any suggestions before I have no more hair to pull out. The dealership just doesn't want to know. Regards, Mike.

Make sure the colorwheel is working. if it is, replace the ballast. the caps are dried out.

Infocus IN10 projector, when I turn it on the light blinks green for a while (with no picture) and then it shuts off and blinks red (more than 5 blinks)


if Lamp or projector shuts off after running a short period of time, This is usually a thermal issue caused by excessively
high internal temperature. The high temperature
could cause a component on the controller ECA or
the power supply to fail when it gets hot.
First you need to check the fan operation, Are 3 fans, two for lamp and one for the color wheel. Check the elevation foot, if something is broke maybe something stop the fan.
Remove the lamp module.
Examine the fan assembly through the recess in the bottom case. Plug the projector in and turn it
on. Both fans in the fan assembly should start up and run for 5 - 10 seconds, then shut down
(because there is no lamp installed). This is time enough to make sure the fans work properly.
Make the same for the color wheel fan, you need to remove the top case.

The lamp on my Infocus Screenplay 7210 shuts down


the projector thinks it is overheating. you may need to replace the temp sensor. it located near the lamp plug. also make sure the fans are both moving.

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?

New bulb worked for a short trail run now wont light up. flashing green led colour wheel is turning on start up


when you changed the lamp, did you blow the dust out of the projector? if the screen on the side of the lamp is blocked (i.e. with dust), the lamp will blow quickly. if the projector were to overheat, by the fans not running or blocked vents, everything would shut down and the led would blink red.

Just replaced bulb when cold it has trouble lighting.


it's not the lamp, it's the ballast. when it's fully discharged, it needs too much power to start. once it has the caps charged (when it's been running and warm), it'll start right away. it sounds as if the capacitors on the ballast are drying up. best to replace the ballast. after you do, make sure the projector is free of dust and dirt. excessive dust will cause premature power and lamp failure due to lack of cool down.

My projector doesn't stay on. what's wrong?


either the lamp cannot strike (meaning a ballast or lamp issue) or there the fans are not up to speed to sufficientl;y cool down the lamp and therefore shut down to avoid damage.

Right , if the indicator light goes from Green to Orange when shutting down , it will be the Powersupply that is giving problems and not the Ballast.
