Power does not come on. Unit has not been used all winter

The unit worked last fall but now only the power LED comes on. The lamp and fan do not come on. I jumpered the internal fan switch so the circuit should be enabled. The DC power sources are not coming up apparently, since the fan is 12VDC. Does someone have a schematic ?

Dear Sir, I have a NEC LT 260 K Lcd projector. The lamp of the lcd was busted.I replaced it with a new lamp. After replacing the lamp the lamp is not lighting when projector is put ON, I think the...


the clicking sound hopefully is the high voltage trying to start the lamp, but for some reason there may be a connection problem between the lamp and the projector power supply.
take the lamp out.

look at the lamp and check that the 2 connecting plugs are ok.
then look inside the projector at the power sockets that connect to the lamp (when it's installed).
check that the pins are not damaged or pushed down too far to prevent the lamp plugs making a proper connection with the power sockets in the unit.

Infocus screenplay 7200 fan failure with new lamp After powering on, red LED blinks 4 times which means fan failure of the fan that is part of the lamp module. Already returned initial new lamp and got...


Not sure if this helps with the 7200 bu had a 4805 with a failed fan issue. There are two fans inthe unit, one smaller one that cools the color (colour) wheel and the larger one that cools the lamp. This unit had a problem with the larger lamp fan not turning. Unplugged and disassembled the unit to get the fan out and tested the fan using a 9v battery and a couple of wires (best to uplug the fan from the controller board so you are not forcing voltage into the unpowered controller board... that said, I did it hooked up just peeling back the label in the centre of the fan and touching the wires to the solder contacts) The fan worked fine so figured the controller board was the issue, so this wasn't going to be a simple "buy a new fan" issue.

Here is where your mileage may vary...

I decided that it would be OK to just run the fan. Unplugged the fan and powered it from the 9V battery and assembled the unit and powered it up. Found that there was 7v available on the power board at the second pin that was alwasy on when the power switch was on (thats the positive 7 V pin, but measure it with a meter since we are talking about a different projector) and just wired the fan direct to pin 1 and 2 (1 is ground on the 4805, 2 is +7V) and so now whenever the main power is on the fan runs, so after ti cools down I just power off the main power when not in use... or let the fan run if the noise isn't an issue. Crude but effective fix.

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.

My Viewsonic PJ458D lamp not coming on


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.

Unit will not Power Up.


Hi, we had the same problem... Bought a new lamp and then encountered the power light blinking repeatedly problem. After much frustration and anquish, we finally got it to work again... The way I did it was, take out the power cord from the back, then hold down the power switch and re-insert the cord. Somehow it made a difference to the unit and it powered back up all fine.. Cos we heard the fan come to life properly.
Cant guarantee it'll work for everyone but give it a try all the same.
Good luck
