Question about Zenith E44W46LCD 44" Rear Projection HDTV-Ready Television
The power light blinks then after about 10 seconds there is a short
buzz sound (sounds like its from the lamp area). Picture used to come
on at this time. But now is buzzes the green light continues blinking
and buzzes again. This happens 3 times then the Indicator light (middle
light) blinks red for about 5 seconds the the power indicator goes back
to orange (standby mode / off).
Tv has been having this problem off and on. But usually after sitting a day or few hours it will come on. Now it doesn't come on at all.
No dust on fan (cleaned filter). And lamp cover switch seems to be engaged. Don't know anything about TV's but if this is a bad lamp and it's not too hard to change I'd give it a try.
Any advice from this knowledge base would be appreciated.
TV is 2 years old.
I have similar problem with my Toshiba 46MW48. A buzzing noise for few seconds the Tv attempted to restart. Took to repairers and they want over £500 to replace lamp and ballast. I cannot aford this.
I have replaced Lamps before, and can get a ballast for about £90
Can anyone offer any advice on fitting toshiba ballasts? They look like computer circuit boards with a metal back and the brown connector which fits into the lamp unit.

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.
