Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced.

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

My Vizio m420nv tv the left half of the screen has a yellow tint throught the whole screen. the right hand side is fine. Ive changed the T Con Board and didn't change anything. any ideas?


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.
http://electronicshelponline.blogspot.com/
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.

My Vizio E420VL would not power on.


It is possible you have a faulty main board. The main board is in charge of sending a signal to the power supply to "turn" on the set. So assuming your replacement power supply is a working board, I'd lean towards the main board. I would recommend getting a professional diagnoses to be sure.

Vizio m420nv has sound but no picture


Hello there

Actually that problem is very common on all LCD TV,, that problem is cause of either inverter board or t-con..

In this case you don't need to check the voltage that is too complicated for you,,only visual check is enough..

I share you my tricks and hope it helps..

Power on your TV turn off your lights..if you will see the light comes from the screen the problem is t-con..if no light the problem is inverter board (backlight) board

Hope it helps..

Don't forget to rate..

Green light turns but tv wont turn on


if you have sounds and backlight replace t-con board..if no backlight but have sounds inverter board..

if no sounds or backlight try this...




That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Good day!!!

That problem is usually cause of bad inverter board or T-con board also there is the possibility that you have failing capacitors....

If your TV is totally black even back-light the problem is inverter board..please try to replace it to fix your TV.


If your have back-light but no image comes out...The problem could be on the T-con board..if that so please replace it...

This is for bad capacitors...

1. Open the back cover of your TV.

2. Look at the power supply board..Its normally connected to the power cord..

3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
