The back light is working but not the main section for the picture. You will need to check on thenmain board for signs of dry soldering on the power section of the board. Check for loose connection to the convergence IC ,solder the pins and check . If can be faulty.
Look for capacitors that have leaked if so replace after cleaning the area.

How to troubleshoot lcd tv


If you are using the ANTENNA input mode of the TV and should be receiving a local station on a properly chosen channel then something is wrong with the RF or IF section inside the TV. If you can connect an external video source to the TV see if that works while selecting the proper input mode.

Sharp tv has small black and white image in black and white and half screen pink


Sounds like your LCD Control board went bad. Very small chance it is your main board since you said you cant bring up a menu.

I've also had a popping noise on our 50" LG plasma TV, however the picture has not gone, but has turned grainy and colors are weird. Can this also be a blown fuse or a more severe problem (ysus board or similar)?
