Could be a bad ballast or light light control circuit. I have also seen a burned or bad socket cause a problem with this set. Good Luck

It looks like your ballast board is going bad, this is a common problem for DLP TV's the ballast board is the power source to the lamp and if for any reason this board does not send enough energy to the lamp it will turn off, It looks like your ballast it starting to get weak it gathers enough energy to turn on but gets weak again and turn back off you have a new lamp and it requires for the ballast to be working at it's full potential

KF42WE610 bad lamp... and ballast?
Hi,
DLP Lamp has electrodes inside and ballast generates high voltage that makes spark on these electrodes thus got high bright light. New lamp wont die due to bad ballast so replace lamp and see tv works or not.
This tv has self diagnostic feature, turn On tv and let it shut down, now check standby light that would be blinking in specific order, for example 3 or 4 times blink then pause for 3 seconds and again blinks.
Let me know how many times standby light blinking in this tv to help you with more info.
Thanks.

Zenith E44W46LCD 44 in. Rear won't start
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.

Won't turn on.. Operation indicator is red, Lamp indicator is flashing red??
According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.

Tv keeps turning off
If it's staying on for just a short period of time it sounds like there is a sensor that is giving the unit a faulty condition (Perhaps for reason or due to a fault in the sensor). There are normally a few temp sensors in the TV around the Lamp and Ballast. They may be bad, or the lamp or ballast is just generating too much heat.

RU44SZ80L LCD Projection, triangular image in center of screen. Triangular yeelowish blue image on screen when TV is on. Also seen durring black screen conditions. Probably LCD in Light engine. Can a kit be purchased to repair this? Light engiine is extreamly over priced new. I can send it in for repair for $325.00 still expensive and not necessary as I can repair this myself, just looking for a repair kit. What usually needs to be replaced for this king of a failure. Where can I get discrete parts? Thank you.
