To do this, press the ENTER button on the TV and the MUTE button on the remote at the same time. After 5 seconds the screen should come up and it will read "Lamp use time...Total lamp use time ....lamp reset" Press the center button on your remote (the circle button right in the middle of the four directional buttons) and you will be reset to -0- again. Your orange light should now be off.

Normally the main cause of any DLP having a dark picture is the lamp. I would replace it and it should look like a new set again.

I got the same problem i was told when the lamp is at the end of its life the power to the lamp is reduced so it will not blow the lamp and cause other problems with the tv. so when you replace the lamp the tv still thinks its got the old lamp and keeps the power on at a reduced level. the only way to fix this is to reset the lamp clock , this is done in the hidden service menu to access this menu hold the menu button on your tv and remote for about 6 seconds and it will appear. this is as far as i have got with this problem cause nobody seems to know where to go from there. lg are a no help they told me to pay for an lg service men to come out and do it for a price that could buy a new tv. and be carefull if you mess with the settings in the hidden menu you will screw you tv for good and not be able to use it at all. good luck in your hunt for information if i learn anything new i will post it

What is the life span for this tv? I am having a problem with some static or ghosting for about 1 minute and then the tv shuts down.Cable co. came checked everything and said its the tv.Have had it for 6...


Life span of no TV can be predicted. It can be according with its usage time and so many other things. I know a Sony 19" tv working perfectly since 1981. Some sets' life will be short, while the others will last long. Normally, a TV, which is used at high brightness all the time, like open bus stations and hotels etc will not last longer. Its picture tubes' emission will go out in no time. OK.

Rear projection TV (LG 44SZ51): Horizontal dark band on upper screen field

The LG 44SZ21RB Have a problem with their light tunnel collasping due to the heat from the lamp. They are available as a spare part @ LG and would also require some silicon adhesive to bond it into the assembly. Very tedious job for any technican (2-3 hrs). Lg will not release parts to the general public only to an authorised LG agent.
