After replacing bulb which was nearing end of life there is an overall yellow tinge to the projected image.

It's probably telling you that your bulb is nearing the end of its life. (At least it's doing its job -- half the time these things give you no warning at all.) So buy a replacement bulb for the day when the old one dies. You can turn off the annoying light by going into your set's menu and telling it you've just replaced the bulb. Be sure to do that again when the bulb actually dies and you replace it, so it doesn't give you a very early warning next time.

Hi,
From my experience, the projector bulb has most likely received a blemish of some kind from something such as accumulated dust on the front, to a fingerprint from where it has been handled by someone replacing it.
This yellow tinge then occurs when the blemish is burned onto the surface of the bulb.
In my opinion, unfortunately, you may need to get a new bulb.
Hope this helps!

Reset it should be something in the manual that tells you how to reset the defaults on TV.

Ur tv have bulb,it a lamp that project the picture.It have life spans about 1400 hundred hours.It come close to the time near the end.Change another lamp when the front LED lamp indicator flashes.

If possible, try to replace the VGA cable between the projector and the computer. A bent or broken pin, or a damaged wire, can prevent the blue or green (or both) portions of the picture from being displayed. The result is a reddish/pinkish picture.

As for the long time to project an image, this could be an extended warm-up time. How old is the bulb in the projector? Does the projector have an option to display the hours used and/or remaining on the bulb? Bulbs do have a finite life, and when they near the end of their service life, they can become more difficult to start.

Hope this helps!

Many projector bulbs will go yellow when they near the end of their life, is it an old bulb?

If you put magnet speaker ( Standard speaker) near the TV, first you must move that speaker away from your TV because this will cause your colour TV screen color scattered. Then switch off your TV for 5 hrs. then switch it ON again your problem will be solved if the degaussing coil working.

I'm sure that many lamps in these models get replaced unnecessarily. The problem is the contacts where the lamp assembly plugs in. Remove and replug the lamp.. Mine has aluminium foil jammed in the connectors for 2 years now and hasn't failed since.. Prior to doing that I had EXACTLY what you described. No more LG for me

tv is on it's 'hospice' end of life routine..unless you want to gut it completely, and replace all the electronics..

All fillament based lights will dim as they age. Some of the newer/better types it will be unnoticible.  If you are losing image quality or brightness you may have a bulb that is nearing the end of it's life cycle.  A glance at you owners manual or the manufactor's website should give you an indication of the expected life of your bulb.  Also most of the projector made in the past few years have a counter that tallies the amount of hours your bulb has been on.  A more likely culprit is probably dust accumilation somewhere inside your projector. Most projectors have filters these days and need to cleaned at certain intervals and in certains ways.  Not cleaning these filters can cause heat build up that can increase operating temps and shorten the life of your bulb and or projector.  Or sometimes jsut fail and cause a dramatic decrease in image quality.  Again these things are vendor/model specific so you will want to check with them about your particular model. Hope this helps.
