Display problem after bulb change

Everything was working fine when I changed my lamp. After replacement I turned it back on and the display was cut in half my a largeblack vertical line. THe top part of the screen was displayed at the bottomand the bottomof the screen started half way up. It reminds me of when the vertical is out on an old TV and the screen is slowly scrolling up. I hope that makes sense. I have tried evverything and have been searching for an answer for hours.

Can hear sound but cannot see picture


Hi, if your LCD projector turns on and projects light with sound but not the picture on your computer screen, first make sure the projector is plugged into your computer. If it is, check your computer display settings. Go to "Control Panel" and "Settings" or "Windows Setup." Select "Display." Make sure it's set to appear on your laptop screen and the the projector screen. Most laptops have a "Fn" key dedicated to changing the output display setting.


If your projector turns on but emits no light or picture, replace the projector's bulb, often called the lamp. Most have a life of between 2,000 and 6,000 hours. Your projector may warn you when the lamp life is about to expire, although some models simply stop working when the lamp needs replacing.



Thank you.

Dell 1209S Projector, tries to turn on, and the fan comes on for 30 seconds and then goes off again. It tries this several times and then the light bulb icon comes off and it doesn't do antything else


Lamp is burned out or makes a popping sound.
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.
LAMP light is solid amber If the LAMP light is solid amber, replace the lamp.
LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down.
If the LAMP light is blinking amber and Power light is solid blue, the color wheel has
failed and the projector will automatically shut down.
Unplug the power cord after 3minutes then turn the display on again. If this problem
persists, contact Dell™.

It is possible that the LCD within the unit could be the suspect as the display could have developed a change of colour. It is important to check if the lens or the lamp has any issues and if not this colouration which is permanent is from the display unit.

I have a BenQ PB 6210. After switching it on, it first displays that the lamp has run 2001 hours and should be replaced. After this window disappears, it takes maybe 2 seconds and the projector shuts...


Hi cholthusen,

Please be informed that the average lifespan of a projector's lamp is around 2000 hours. The light bulb is almost certainly the problem. The best solution would be to change the bulb. The easiest way to do that is to change the lamp assembly (fresh bulb is in the new assembly). You may also try resetting the unit. Turn the unit off, then physically remove the power cord. wait for about 10-15 seconds then start it back again. If this did not work, please replace the lamp.

Hope it helps.

Thank you for using FixYa.

How to change the bulb?


hi,
do the following steps to change the lamp of your projector.

1. Turn the power off and disconnect the projector from the wall socket.
2. Turn the projector over. Then loosen the screws and remove the lamp cover. If the lamp is hot, avoid burns by waiting for 45 minutes until the lamp has cooled.

3. Move the latch to another end as shown in the picture.

4. Loosen the screw that holds the lamp to the projector. If the screw is not loosened
completely, they could injure your fingers. It is strongly recommended that you use a
magnetic-head screwdriver.

5. Lift the handle so that it stands up. Use the handle to slowly pull the lamp out of the projector.

6. Insert a new lamp. Make sure the handle is fully locked, move the latch back, and
tighten the screw firmly.

7. Re-install the lamp cover and tighten the screw. Do not turn the power on with the lamp cover removed. Whenever the lamp is replaced, reset the total lamp operation time. Do not reset if the lamp is not replaced as this could cause damage.

8. Resetting the lamp counter
i. Press and hold the Exit 5 button on the projector for 5
seconds to display the total used lamp time.
ii. Press Auto on the projector or on the remote control to
reset the lamp hour to "0".
iii. Wait about 5 seconds to let the OSD disappear.

ok

Not bulb related, it is related to the i/o board on the back of the projector. Something is shorted or making poor connection

Reset The Lamp Timer.

While simultaneously holding down (+ . >) and AUTO SYNC on the projector, Press ( I ) ON and ( - . < ) on the projector.

"LAMP 0000H" is displayed, indicating that the lamp timer is reset.

NOTE..... Make sure only to reset the lamp timer only when replacing the lamp. If you reset the lamp timer and continue to use the same lamp, this may cause the lamp tp become damaged or explode...
