Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. .

You have a problem with the Formatter Board. This is placed between the Light Engine and the Fan. If you are planning to do this your self, before you buy make sure you get the right part since there are 2 different boards. This part cost about $60 and it is relatively easy to install. It requires patience, latex gloves, pointy pliers and both types of screw drivers.

the connector itself can be replaced but I would also make sure the lamp fan is running properly and isnt full of dust. that is what usually happens.

Hello, there are several things, a bad ballast board that provides the lamp with it's voltage to run it. Also a bad power supply can cause it. a bad Color Wheel will also stop it from coming on, if you heard a high pitched squealing sound before it went out, the color wheel would be my best guess.....tks

use the original remote to change the SOURCE to HDMI

it sounds like you might have pinched a wire or something. Hopefully nothing serious has been damaged. Open it up if it is together and check ALL of the cables that go to the light engine and such and make SURE None of them have been pinched or shorted against the frame. Then after all is clear--try the power again.

Make sure the speakers have not been turned off in the menu. If not--the amp chip in the Tv could have been killed. Along with a fuse or resistor in line with it. Not usually a hard problem to fix.
