It could be thru the power surges that you must be having but not noticeable.
Usually the bulb goes out because the power supply is not constant so when there's a surge this is what happens to electrical/electronic equipments.

Zenith 44" LCD TV


The yellow spot is due to the BLUE LCD and/or lens assy cracked, reason, to much HEAT! The blue is the darkest color and hold the most heat, so it goes first, always! In some cases it’s only the lens, however most of the time LCD is damage to. Parts are available, however install and alignment is timely. Quick fix is the complete light engine, which for model# E44W46LCD is part# 3141VSN916C, which customer cost is $1,449.27, wholesale for about $1,065.21. Rebuilt, if you can find it around 850.00 to 950.00. However the rebuilt does not always look as good as factory. My advice, TRASH set. This part will fail again in about 3 to 4 years, unless you watch a lot of white video. Remember, on a black or dark picture, all three LCD are blocking 100% of the light, causing extreme heat within the light engine. It’s a bad design.

BRIGTHNESS TO LOW


Light in wrong, however I wouldn't waste the money on this unit. Light engine will fail in 3 to 4 years and show a yellow spot at first.

(ie past post)
