You'll need to replace the main board. That is the one with the tuner and all the input connections on it. You can do this yourself . Get the part from: TV Parts Universal TV Stands DLP Chips ShopJimmy
The tv have a long board that call the LCD inverter board it is dead.This long LCD inverter board only job are to provided a backlight for the tv LCD screen panel to produce a picture.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish long LCD inverter board for the replacement.
If it is only the screen going black but the TV remains on and you can hear audio, then there is a problem with the backlight. It could be due to bad capacitors or it could be a faulty inverter. It requires repair by a competent engineer.
Take out the piggy back signal should solved this problems,not than ur Tuner Signal board have some kind of intermitten short in the board.Must replaced the bard.
There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. http://en.wikipedia.org/wiki/Capacitor_plague Please post back what you find.
