I have a dell 1209s projector and the temp symbol flashes. I dont know if I need a new lamp or what? Help me? thanks

Anything is usually fixable. What you have to determine with Dell's assistance is if it is cost effective to do so.

This is going to be the lamp itself. Once you replace it will have to be reset back to zero hours to work properly

follow this steps and fix it. God bless you

• 
  Secure the lamp cover and the air filter cover of the projector body if the projector does not power on. Ensure that the power cable is firmly connected to the projector and an active power plug. If the projector was turned off and then on quickly--let it sit for 90 seconds before trying to turn it on.

  Replace the projection lamp if the projector will not power on or if the lamp indicator is flashing. Turn off the projector and let it sit for at least 30 minutes. Locate the lamp cover and remove or loosen the lamp cover with a screwdriver. Carefully remove the projection lamp from the projector housing using the handle, if available.

  Place the new projection lamp into the projector housing and secure it to the projector. Replace the lamp cover and reset the lamp timer. Power on the projector to ensure the new lamp is working correctly.

  Remove the projector from the enclosed area to allow air circulation if it constantly overheats. Place the projector into an open area and make sure there is no blockage for the ventilation holes. Unplug the projector for at least 45 minutes to allow it to soft reset.

  Clean the air filter to allow the projector better air circulation. Turn off the projector and unplug it from the outlet. Remove the air filter cover and use a vacuum to remove dust from the area. If the filter is unable to be cleaned correctly or is damaged, then replace it. Pull the air filter from the projector and place the new one in the now empty slot. Close and secure the air filter cover.

When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.

It may be a faulty lamp module, Have you replaced the lamp at all. It may be at the end of its life.

www.avprojectorlamps.com is probably the cheapest company to use.

It is checking which sources are active (plugged in and on).
There is an option to just select 1 source as default.

Hello.

Look at your computer's function (F) keys. See which one has either a screen symbol or the words "CRT/LCD". Typically, it's the F4 or F8 key.

Hold down the Fn key and press that F key and after the first, second or third try, the presentation on the computer should display on your projector's screen.

Hope this helps.

switch your computer on first.
switch your projector on second.

Try fn + f8, then wait and see if the projector detects the port (15 seconds or so) if no change, try Fn+F8 a 2nd time
