    I have two Viewsonic PJ501 projectors with the same problem. When the power is turned on, the "lamp" light is red and the lamp will not come on. I have replaced the lamp in both projectors, but still have the same outcome. When I check the lamps, they do not appear to be "burned out."

    I have a Panasonic PT-LB10E projector that has had the bulb replaced but now shows a flashing red "lamp" light & will not come on.

    The fan is running but nothing from the bulb.

Hi there

This could be a faulty Ballastboard ( Lamp's Power Supply )
I get this sort of problem all the time and it normally solves the problem by replacing the ballast if the lamp still won't strike after replacement.

Put new bulb in it wont strike, put old bulb back in (worked before0 and it wont strike WTF

Make sure the lamp connector in the projector has not been pushed in as I have seen this happen on a couple of LP540 and LP640 projectors.
If the connector is pushed in the connector on the lamp will not make contact and strike the lamp.

I have two issues with the pb8220 1. How do you reset the bulb hrs when a new bulb is installed? 2. Projects for about 10 seconds then goes black. The red bulb light comes on when the screen goes...

Reset the lamp hours as follows.
Press the Exit button on the projector for 3 seconds to display the total used lamp time. Press the MENU button on the projector during the lamp hour message. An adjustment message will appear. Press left or right arrow to reset lamp hours or press EXIT to leave.

Your new bulb is not lighting.
Check the connections are correct.
Have you also tried putting back old bulb to see if it works.

Our mistsubishi hc1100 projector has green light saying it si on but nothing on the screen, lamp change 2mths ago limited use.

If you have used it since putting in the new lamp, then it could be the lamp again. Take out the lamp and inspect the bulb through the square opening. Look at the wires that connect to the top of the glass bulb if broken or the bulb is damaged, try to return it under warranty. The other issue could be the lamp ballast or power supply. Hopefully the lamp.

I had a bulb burn replaced both bulbs worked for a couple of days but now it wont power up only lamp1 light blinking. I have tried taking bulbs out and putting them back in still nothing, also the lamp...

the lamp units should be properly aligned with the 2 very tiny switches
between them. If not lamp led will blink.
If lamp led is continuously on, lamp timer has to be reset, according instructions that come with new units.
Original lamp modules are AH-45001 and AH-45002, two different
units needen for 1 projector, reset procedure is different for each lamp !!

The lamp continues to flash red lights for power and lamp

I have the same problem as posted too, ordered 3 new lamps and they all still do the same thing. I`m starting to think its the projector that has a problem. Anyone got a solution other then keep buying new lamps and try getting it to work... I mean, after 3, how bad lucky can you be that they are all bad lamps...

Did you reset the lamp timer ?

If the lamp timer has been reset , then you might be looking at a faulty Ballast ( lamp's powersupply )
