Not uncommon for the fan to stay on for a few minutes after the set is turned off. It is designed that way and then supposed to shut down after a few minutes. If it does not then that circuit is defective.

U can always throw a switch in series with the fan and shut fan off after you turn set off. Or if you wanna be fancy you can rig up a relay setup that will turn the fan on/off as you do with the tv.

Hi Kenny
Being a projection device... Which most TV's aren't ...
You need to break the fault down into the Projection Section or the TV Section.
Or Power Supply Section
Projector bulb blown, overheating etc.
Power supply sensing overload or fault then automatically shutting down.
TV Section may be OK
small internal LCD screen is projected by lens.
Check internals.
Happy Troubleshooting

not the lamp. Its a known issue with the power supply. Bad capacitors usually. this requires a servicer to repair it.

press the power button onthe front. if nothing happens please post back with what indicator lights are flashing and how many times they flash. Be sure the lamp door is secure or it will not turn on.

The Ballast plug melted due to age of the TV. as the plastic gets old it gets brittle and can crack with barely any force. The pins then do not seat and the arc that should be in the lamp takes place in the connector. I have seen this so many times. fortunately it is very easy to replace the connector is you know how to use wire crimps and can source an old female plug. eBay is a good source. you can buy a used ballast from any model that has the same connector. Then cut off the new plug and splice it onto your old wires with but-crimps and shrink tubing.

You are going to ruin the optics using a Xenon lamp. The ballast in the TV talks back via UART to the CPU. By removing the ballast the TV cannot talk to it and run itself properly. Also using a xenon lamp will give terrible color reproduction as its not putting out nearly enough lumens in the right spectrum. It will also bombard the color wheel and DLP chip with UV light and ruin those as well.

Fault to the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
