Vizio e65x-c2 led tv has no backlight but has sound and display works when shining a flashlight on it. What board should I replace?

Chances are its not a board issue but bad LED lamps in the panel, you can measure the voltage at the LED output from the power supply and see what you have there to get a better idea whats going on

How do I get the picture back on my LG LED 50 flat screen? Sound works, no picture.

-You have a bad panel. Led arrays internal to the panel are defective. Replacement cost exceeds economical repair.

Power led light

You need not worry, it appears the LED light is a little faulty and your switch mode power supply is OK.
If you are worried then replace this LED.

Three out of the five plugs do not work have stopped working.

The APC UPS will power the non-battery (label something like surge only) with the power button turned off. If the outlets that are not powering up are labeled Battery/Surge, you need to turn on the UPS. There should be a button you depress to turn the system on.

Also if this is a new UPS, you will need to hook up the battery for this to work. Open the bottom of the unit and you will find the battery and plugs.

RCA RTD315W Receiver/DVD LED display

If you are referring to the information display, it doesn't activate until you take the system out of standby (the bright blue LED at the corner is shining). When you hit the OFF button (on the system or the remote) and the blue LED shuts off, your info display comes on and says WELCOME.
