SOURCE: Status light is blinking red,

Hello
Look at the number of blinks of the status light.
[1] If it blinks at one cycle (0.5seconds On and 2.5seconds OFF) : Lamp cover error or lamp housing error. Replace the lamp cover or lamp housing correctly.
[2] If it blinks 2 cycles (0.5 seconds ON and 0.5 seconds OFF): Temperature error. The projector is overheated. Move the projector to a cooler position.
[3] if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.
[4] If it bliks at 6 cycles (0.5 seconds ON and 0.5 seconds OFF): Lamp fails to light. Wait a full minute and then turn on again.
[5] If it blinks continous (Red): Lamp has reached the end of its life. Lamp replacement messege will be displayed. Replace Lamp with same type and number. After replacement reset lamp hour. OK.

SOURCE: No Picture on my nec VT676 model

Thanks. NEC did not have a solution for us, but the solution for us was to replace the bulb. You'd think they would make that a bit more obvious!

Thanks.

What to do?


1. Unplug projector and wait a minute or two. This will reset the projector.
2. Try a new (or a known-good) lamp.
3. Contact NEC. I wasn't able to find a service center in India, but here is a link to their global website:

1,Check the fans ,whether each fan is running,when you turn on the projector
2,if the fans run, then ,check the lamp or lamp ballast
turn on the projector ,at the same time ,if you can hear a continuous beep beep sound (the ballast igniting the lamp)
means the lamp may be fault,and other parts is working well

NEC LT265 PROJECTOR WILL POWER UP BUT WILL NOT COME ON. BULB IS A YEAR OLD. WAS PLAYING A MOVIE WHEN IT WENT OFF AND WILL NOT COME BACK ON. NOR WIL THE FAN RUN. POSSIBLE BALLAST?


It cannot be a ballast because the fan would not run off a ballast. Sounds like a serious hardware failure, I would check with the manufacturer.

I have owned a Sony Grand Wega for about 3 years now and for the past few months the TV has been making a very loud noise. I thought the noise was the fan but came to find out it was not the fan and was...


Hello,

There is a fan beside the lamp chamber in this TV. There should be 4 fans total, and the one beside the lamp chamber might be making some noise. They are all bearingless fans, so the noise should be relatively low-pitched "whirr" if it is the fan. If the noise is more of a buzzing sound, it could be coming from the lamp driver (ballast) or from the lamp itself. Lamps tend to do strange things toward the end of their life.

If you have never changed the lamp, it is about time. They have a 2.5 -3 year life span with average use.

One thing you can try is to turn the TV on from a cold start, and watch inside the vent areas beside the lamp chamber. If you hear the noise before you see the lamp light up, then it is probably a fan. If it starts as soon as you see the lamp light up, it is the lamp or ballast.

Hope this helps you...

Lamp light blinks 3 times shuts down


The CLS problem. Im thinking that at least you made a visual inspection of the power suply and the capacitors around it. Then if everything normal in the area then the microdisplay (inside the ligth engine) can be damaged. (when the tv is working normally the microdisplay sends a pulse to turn on ballast and lamp finally.

The sweetkyman: when the fan is bad th tv shuts down imm. (if you unplug the fan when the tv is working normal the computer detects the overcurrent system works and shuts down the set) when a fan is all dirty and tons of dust on it the tv tends to work but after some hours the tv shuts down.
