Vivitar 3000af slide projector


While I am not sure of this feature on the Vivitar projectors, extensive testing has proven that running the cooling fan to accelerate cooling of a projection lamp will significantly shorten the lamp life. It is always recommended that (if possible) the projector system is cooled to room temperature without the fan running. Also, it is recommended not to move the projector until the lamp is completely cooled, as the lamp filament is extremely fragile when hot.

AUTOMATIC SHUT DOWN WHEN THE UNIT IS HOT


hi,
First you have to check the lamp cooling fan of your projector. If the lamp cooling fan of your projector is faulty or it runs in a low speed this problem can occur. Another possibility is the faulty temperature sensor. you have to check the temperature sensor near the lamp. normally a sensor with two wire fitted on the lamp Cage.
if fan is suspected then remove the fan and try to oil the fan and the re fix it and try again. for oiling the fan watch the following video.
The video is for oiling a pc fan you can follow the same to oil the lamp cooling fan
ok

2.select menu and the select lamp setting

After doing this if the problem remains then you have to check two things. first you have to check the lamp cooling fan of your projector. If the lamp cooling fan of your projector is faulty or it runs in a low speed this problem can occur. Another possibility is the faulty temperature sensor. you have to check the temperature sensor near the lamp. normally a senor with two wire fitted on the lamp Cage.

My televison keeps turning off after being on for about 2 min. bulb has already been replaced.


Sounds like it is heating up on the inside. If you take the back cover competely off you will see that you have 4 fans on the inside, 2 big fans one on each side, one to cool the lamp and either 1 or 2 little fans which are located on the electrical box on left side and sometimes one that is mounted behind the DMD Board which is located behind the engine assembly. Because it is shutting down it tells me that the fan to cool the lamp is faulty. What happens is the fan cools the lamp, if the lamp gets too hot the television shuts down to protect itself from damage. Because AKAI parts are extremely rare to find I recommend not attempting to even turn on the television until you are able to replace the lamp cooling fan. If you see it is spinning it doesnt always mean that it is working because it may not be spinning fast enough. Good luck in finding a fan for it.

Lamp cover melting


Open the back case (about 10 screws) and clean the lamp cooling fan. This is NOT the one you can see from the outside. It is located in a horizontal position above the lamp area from the rear. A DRY toothbrush can be used to brush out the dust. Keep a vacuum nozzle next to it while cleaning so the dust does not go inside. Some say to use compressed air to blow out the dust, but vacuuming it keeps better control and can prevent unwanted dust from moving down into the optics.

I learned this the hard way when replacement lamp burnt out in one week. I thought the cooling fan that you can see from the outside (it actually is the exhaust fan) was the only fan. The lamp cooling fan sucks in cool air and puts it right down onto the lamp.

Test the fans by turning on unit without lamp installed (the fans will power on for a short period of time and you can see them function to verify airflow). Clean this fan once a year as the dust will be back.

If my lamp is out, would sound be present?


Check lamp cooling fan for dust blockage. It is located inside the back cover (10 screws) and is in a horizontal position above the lamp from the rear side. This is an air intake fan. The cooling fan you can see on the back panel is the exhaust fan that sucks out the hot air. A clue is hot or melt marks around the lamp housing.

If the lamp cooling fan is blocked you'll get red flashing diagnostics light flashing. It's trying to say clean me so I can keep the new lamp cool. Sony is silent on this in it's manuals. I'm guessing they don't care because is causes lot's of parts business!

I learned all this after replacement lamp burnt out after 1 week. My lamp cooling intake fan was found blocked and wasn't spinning. I saw the exhaust fan working and thought all was ok, not even knowing there were more fans. Some models even have another fan inside the optics blocker. I didn't take mine apart that far.

Here is the proceedure to replace the lamp and reset the lamp hours.
Lamp Replacement Procedure:
1. Press the POWER button to turn off the power.
2. Wait for about 1 minute until the cooling fan stops.
Note:
The lamp cooling fan will continue to operate for about 1
minute after the power is turned off. Do not unplug the AC
Cord from the outlet until the fan has stopped. Avoid
interrupting the power by using circuit breakers or switchable
power strips.
3. After the cooling fan has stopped, unplug the AC Cord from
the outlet.
Note:
Please wait more than one hour before replacing the lamp.

If you need to replace the lamp more urgently:
- The Projection display has a forced cooling feature.
After the POWER button is turned OFF, and during the
first minute of the normal cooling fan operation, press
the VOLUME UP button on the unit and CH UP key on
the remote at the same time for more than 5 seconds.
The cooling fan operates for about 10 minutes. (LAMP
LED will flash 5 times every 5 second and POWER LED
will flash red for 10 minutes.)
4. Remove the Front Cover Unit from the latches.
5. Turn the Knob to the left.
6. Pull the Lamp Cover out.
7. Loosen the Screw on the Lamp. Then, pull the Lamp.
Note:
Because the Lamp may still be hot, use caution when

8. Install the new Lamp, and tighten the Screw.

10. Install the Front Cover Unit.
Lamp Time Reset Procedure:
Be sure to reset the Lamp time to "0" after replacing the new
Lamp.
1. Plug in the AC Cord, and turn on the power by pressing the
POWER button.
2. Press and hold the VOLUME DOWN button on the unit and
the SPLIT key on the remote together for over 5 seconds
in power on condition.
When the reset is finished, the display will indicate that the lamp hrs have been reset to 0 and the LAMP LED goes out.
