To reset the lamp timer, press the RESET button on the projector or MENU button on the
remote while the amp hours are displayed. The lamp hour reset message will display. Use the
left-arrow button on the remote control or the Menu diskpad of the projector to select 0, and wait
until the timer display has cleared.

This is from the MP7640 Manual

Hi, Our Sony Bravia TV model number KDF E50A11E is not working. There is a red blinking light flashes three times and then goes green and then red blinking again after about 3 seconds. Is this a bulb...


On that particular model I believe there is both a lamp indicator light and then the power indicator light. If it is lamp related the lamp indicator light (LED that looks like a sun in a cup...) would be on.

If the power indicator light is flashing red to green, that is a self diagnostic code, and you will have to contact an authorized Sony repair fascility for them to translate the problem. The error codes are not listed in the user manual, since most are not user serviceable.

Red lamp or heat light is flashing while projector is off. Can't be sure which it is because it is mounted 16' up. I've cleaned projector & filter with canned air from 12' ladder and red light stops...


Hi,
Here is some information on this model which I hope will help...
The lamp indicator lights when the lamp is due to be replaced. It will flash if a circuit abnormality is found.
The temp indicator lights if an abnormal temperature is detected. If it goes too high it will shut down flash.
The lamp indicator is furthest away from the power switch if that helps.
If the lamp timer was approaching the end of the lamp life you would see a REPLACE LAMP nag screen when the projector is turned on. The fact that you have not mentioned this suggests that this is unlikely to be the problem.
The filters on the model are on the underside. There is a removable panel directly under the lens. You should not use canned air as you are blowing dust into the projector. It is recommended that you use a vacuum cleaner. Filters should be cleaned every 100 hours and replaced when the projector is relamped. You can wash the filter by hand with water only, ensuring it is dry before replacing it. Do not run the projector without the filter in place.

Canon LV-S3 how to check hours on the lamp? do I have to have unit hooked up to an input source?


Lamp Replace Counter
Be sure to reset the lamp replace counter after Lamp Assembly is replaced. When the lamp replace counter is reset, the LAMP REPLACE Indicator stops lighting.
Note : Do not reset the Lamp Replace Counter until after the projection lamp is replaced.
1. Turn projector on, press MENU button to display the On-Screen Menu. Press Point left or right button(s) to move the red frame pointer to the Setting Menu icon.
2. Press Point down button to move the red frame pointer to "Lamp counter reset" and then press SET button. The message " Lamp replace counter reset? " is displayed.
Move the pointer to [Yes] and then press SET button.
3. Another confirmation dialog box appears and select [Yes] to
reset the lamp replace counter.
Note : Do not reset the Lamp Replace Counter until after the projection lamp is replaced.
This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling may result in accidents, injury, or create a fire hazard.
 Lamp life may differ from lamp to lamp and according to the environment of use. There is no guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their life in a shorter period of time than other similar lamps.
 If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE INDICATOR lights up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down.
( Follow carefully the instructions in the LAMP REPLACEMENT section of this manual. ) Continuous use of the lamp with the LAMP REPLACE INDICATOR lighted may increase the risk of lamp explosion.
 A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its lifetime draws to an end. Risk of explosion may differ according to the environment or conditions in which the projector and
lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN.
If a lamp explodes, disconnect the projector's AC plug from the AC outlet immediately. Contact an authorized service station for a checkup of the unit and replacement of the lamp. Additionally, check carefully to ensure that
there are no broken shards or pieces of glass around the projector or coming out from the cooling air circulation holes. Any broken shards found should be cleaned up carefully. No one should check the inside of the projector
except those who are authorized trained technicians and who are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those who are not appropriately trained to do so, may result in an
accident or injury caused by pieces of broken glass.

It is an indication that the projector is in sleep mode. Press power button and check for any changes on the led indicators. If the power turns red, it means unit is hot. check if the fan is working and if the air filter is clean or needs cleaning. If the lamp turns red it means the lamp is busted, You will experience this since lamp is clearly blown. But if both lights are red, it means that the unit is busted and will require service.

NEC MT1050 Lamp Error


Does the status light stay on red? If it does then the lamp timer has exspired and will not let the projector turn back on until it is reset, at which time you should replace the lamp. To reset the timer you need the remote control, with the unit plugged in in standby mode hold down the power off button for 30 to 45 seconds until the status light goes off.
