Question about Televison & Video

Open Question

I have a NEC vt491, I turn on the power, the power buttons green, fan wirs up sounds ok, then the standby starts blinking green and a light clicking comes from around the fan area, (I think its the ballast trying to make a circuit but discharging freely), than a beeping noise starts him off, the fan rpms go up and the power is orange and the standby is blinking red, I did everything the manual said and nothing had changed, so is it a bad ballast, lamp timing, the lamp, I just wanna knew what's wrong with it. Any answers are appreciated

The buzzing is the ballast for the lamp trying to light the bulb. From what you've described it is a lamp failure. It's not that hard to change but you'll have to obtain a new lamp first. You can try and buy it from LG (800-243-0000) but I'm not sure if they'll sell to a consumer. Then you have to reset the lamp timer after you replace it. Hold the mute on the remote and the enter button on the tv at the same time for about 8 seconds and a screen will come up asking if you want to reset the timer. Just follow what it says to reset it.

SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

I took the rear bottom off of the set,lots of screws to take off.

I took mine completey out,jumped the black wire together,and bingo.set works perfectly.

SOURCE: No picture, green light blinks then short buzz sound

I had the same problem with my TV. I called the Zenith support line and found out my model (E44W46LCD) had a manufacturer's defect and Zenith said they would be taking care of it. I am in the process of waiting for them to let me know how, but they took all of my info and said they would be responsible for fixing it.

Status light is blinking red, power button orange nec vt700


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.

I turn it on, the status light flashes... then it turns itself off, except the power button is still showing power and the status light is blinking red


Your bulb is not lighting.
Either the bulb has failed or it has a bad contact.
Remove the bulb to check condition and then reinsert and try again.
If it still does not light you will have to buy a new bulb.

Hi,
TV needs lamp replacement as existing lamp got weak or has been reached to end of its working life, please note that lamp is not dead or broken so that is why lamp lit is not lit at tv front.
Hope these info will help you.
Thanks.
