follow this recomendation.God bless you
Temperature is a common reason why many Rear-projection TVs do not perform well when they get to hot. You may start to see your TV shutting down automatically when it overheats. Here are a couple of things you can do to prevent overheating. First make certain any TV ventilation ports are free and clear of debris and dust. Second make sure the TV has enough room for airflow. Third, the temperature in the room should be around 72 degrees. Due to the high degree of heat generated by a rear-projection TVs, it is not advisable to watch TV on a hot days when you don't run the air condition. This could cause damage to your TV.
  • Check the fan. Once the television is turned off, it is just normal for its fan to become louder. A projection TV actually depends on its lamp, which requires cooling so that it will not prematurely burn out. If the room where your TV is placed is very hot, the fan would also continue to run.
Replace projection lamp. To properly do this, make sure that the lamp's bulb has cooled down and the TV is unplugged. Carefully remove the cover of the lamp's compartment using your screwdriver (Phillips-head). Unscrew the sealed part of the lamp that can be found at the television's rear part. Take away the old lamp cartridge and then insert a new one. Seal the lamp with screws, replace its cover and then screw tightly.
iF THE Problem persist you have to fix it the power supply inside.
God bless you

The lamp needs to be replaced. It's on the back and easy to do. I replaced mine about 3 months ago and it was about $182.00. Hope this works, I know it's hard to fork out that kind of money at this time but once you do the TV will be as good as new. Take care

When turning on the TV the green light on the front does not come on. You hear a click and then about ten seconds later you hear another click but the tv never comes on.

What light do you get, green blinking, red blinking, yellow steady light or yellow blinking light. The led lights will tell what is wrong with your tv.
