If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

SOURCE: Power Light comes on but no picture or sound.

for your VP50, it could just be simple as a power supply but it could also means more. Do you have the amber LED light when off and green when on? if so, try the main board first. If that doesn't resolve the problem, then change the sustainer boards.

SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

Does LCD screen backlight come on? If so proceed....
USE:CAUTION WHEN DOING THIS....
Try this if repairing yourself...find power supply, small board with no cover over it...check voltages on output pins/plug/connectors (white plugs) three in a row...
1 Plug has 24Volt supply..1 has 12Volt supply and 1 has 5Volt supply when read to ground (screw that holds board in) if you have these voltages it's a safe bet it's the main control board...I just replaced mine and it fixed a problem like yours.

Hello, I watched a of video on Shop Jimmy. They said I should contact you for confirmation.


Take it in for repair. Television repairing is not a DIY subject. The course is 2 years full time.

We see self diagnosis posts here all the time and generally it is I changed this board, that board and that board and it still doesn't work. You can't return any of these parts when you buy them. If you like to have a gamble, sure, go ahead and buy the parts. It SOUNDS like the correct diagnosis, the backlight is gone. How about blown capacitors, have you checked for that?

Vizio TV has sound but no picture


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Vizio 32" hdtv model # E320-A0 Broken Screen cant tell its broken but tv has no picture just sound. How much will i get if i sell it for parts. Barely have a year with the tv.


The board that controls the screen ranges from 36 to 90 bucks or so. You can replace it yourself using only a screw driver to take the back off and the four screws holding the board to the chassis.

My screen is flickering on and off on Vizio LCD TV? I was wondering if it was the main board or the T-Con board.


Flickering can be either with the fault to its back-light inverter or with its main power supply regulator board.

Measure all the voltages coming off the power supply board first. Then move to the board that controls the picture. This board has one or two wide flat flexible cables running form it to the bottom of the screen.

How do I make my remote work? It was working then it stopped. I thought it was the batteries, so I bought new ones but it still wont do anything.


Check the remote control for its infra-red emission. Check it with fresh batteries. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience.
