Cooling Fan for Lamp 50V500A

If it's off balance or spins faster that's going to cause the laptop to "vibrate more", especially if the fan is working over-time to cool down the laptop.

hi,
First of all check the lamp hour of your projector. Just reset it and try again. for resetting the lamp hour do the following.
1.Switch on the projector
2.select menu and the select lamp setting
3. In the lamp setting menu select lamp Reset and execute the same

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.
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

Check the cooling fans. If they are not rotating the Projector will not start.
Did the lamp explode? If it did a bit of glass has lodged in the cooling fan and stopped it from working.
Hope this helps.

driver side strut tower
firs and last relay any way u want to look at it dont mind the other relays just the two outer relays
make sure the ecu signal is working
warm up the car and disconnect fan motor make sure tha you have ggod ground get a test light and check for the litr green wire to see if its going to send signal to the wire

A more likely candidate is the color wheel,unless your sure it's the fan

After i replace the lamp on my Hitachi50v500a worked everything then i turn it off.After 1h wanted to turn it on again and it shows (TEMP) light is that a lamp fan or something else.Please help how to fix it by my self.Coz no money to call the tech.

this set has more then one fan; one fan will run all the time to cool the digital circuit board---if it is the actual LAMP fan then you have a problem---the digital fan is very small and not located near the lamp.

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.
[ Forced cooling function ]
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
handling.
8. Install the new Lamp, and tighten the Screw.
9. Install the Lamp Cover, and turn the Knob to the right.
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.

I have the same problem before. I found a replacement fan. A computer chassis fan works perfect. It should be 60mmx60mm - plenty in E-bay for about $5.00. Very easy to open the unit to replace the fan. It has 2 fans in a rubber housing. Check which one need replacement.

I'm not sure how difficult it is to change the cooling fan, but I saw the part on PartStore.com for only $13.
