LM317T Voltage Regulator with Pass Transistor

Repair on a Vizio 37 inch LCD tv that will power on (power supply is ok), Backlight lights(inverter is ok) But has no video and will not turn off with the power button or the remote. Repair involves voltage measurement and IC regulator replacement.

This is a first rough draft modification for my Spektrum DX7 which provides a backlight for the LCD Screen, enabling you to see the screen in low-light or dark conditions. It comprises of: - EL Panel ( White ) - EL Inverter - Switching Voltage Regulator (5V) - Mini Toggle Switch - Some Red&Black electrical wires You'll also need your own soldering iron and solder to make this setup to work. The setup runs off the DX7's battery. Using the Voltage Regulator means that it uses less power. This is just my first rough draft of this mod to check that I could get it to work. Next steps are to use thinner red&black wires as the existing wires I've bought are too thick and stiff. Then after that I hope to get this setup installed into the DX7.
