SOURCE: Vizio VO420E " TURN ON, tv is showing no picture

It can be the main board, power supply, backlight inverter, etc.
You need to do some troubleshooting to narrow down the probelm, so please read my guide first.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

SOURCE: can i replace a vizio screen model #VO420E with a vizio screen model #VO42L FHDTV10A?

Hopefully you did not try to take the circuit board from the broken LCD and graft it onto the good one - the possibilities for problems are enormous.
Double-check all of the connectors, then compare the model numbers of the main board and power supply between the two sets. The cable between the LCD and the main board is often rather fussy and delicate - DO NOT pull on the wires! You may have to swap cables also. If the main board is different, try the one that went with the good panel (from the VO240E), and hope that part is good.
Note: electronics are susceptible to damage from static electricity. Handle the circuit boards only by the edges, and try to maintain contact with the metal shielding parts as much as possible (an anti-static wrist strap is a good means) while working on the set to discharge any static buildup on yourself.Once you are done, there is an e-Bay market for the remaining parts. If you have identified the bad board from the VO420E (by elimination), you can get more for the others, and you may still be able to sell the bad one to a reconditioning company, who will repair it and resell it.
The worst case situation is that the LCD panel driver board is bad, but as I understand your situation, the VO240E wouldn't turn on anymore. That is usually a power supply problem.

We replaced the IR sensor on our Vizio but still cannot control the volume via the remote (which has tested good). Any further suggestions?


Since sensor is receiving the signal of other inputs, there is nothing wrong with it. This looks like an incompatibility issue. You may have to retry using the original remote control.

Cable remote AND vizio tv remote will not turn on the tv


We will presume you do not have two bad remotes---the fact you can operate the set manually with the buttons there suggests a problem with the remote receiver====there is a tiny infrared receiver in the front of the set that receives the signals from the remote and sends them inside the set where the correct action is taken.

Make sure if you see it (usually small black area on frame of set) it is not blocked or dirty.

Failing that you may have a bad receiver for the remote---shop repair.

Cant control tv from remote


Lets find out first if it is the remote controller or the remote IR receiver in the TV problem.
New batteries?
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

Remote stopped working Got new remote and it


It can be the IR remote receiver board inside the TV. Is the new remote setup for VIZIO TV?
Old VIZIO remote is bad for sure?

My dish remote for my new vizio tv only works part-time. the volume and power work, but the guide button only works less than half the time and only after holding it down for 5 seconds. i have exchanged...


judileighahl,

If you have replaced batteries and had a new remote sent out to you, either the Vizio TV is emitting an IR signal that is interfering with the remote IR signal to the receiver. To test if the TV is emitting interference, is it possible for you to turn the receiver in a direction away from the TV and see if the remote will work? If it does work after moving the receiver, that indicates interference from the TV. If it doesn't change the situation, you might check for other interference from other components (florescent lights, etc.). I hope this helps.

Bought new Vizio 55"


Had same problem - turned off Adaptive Lumina, Backlight control, and Ambient light sensors on the Vizio advanced picture settings and the Dish remote now works. Vizio was emitting an infared signal that interfered with the Dish remote signals with these settings on. TV still works and looks just fine... But best of all Dish remote works too.

I was watching t.v. my grandson called then i looked at the t.v. and it said no signal. i have tried unplugging it and turning it back on. i have changed the batteries in the remote control. nothing...


This seems to be due to the TV being on the wrong input. Use your Vizio remote and cycle through the inputs until you reach the audio inputs. Try all of them with the receiver on and the amber,green and blue lights on the receiver. If you do not see a picture here the TV may have been connected by coax. To check this go to th TV input using your Vizio remote and key in 03 or 003. You should be able to see satellite now. It will also depend on how your system is a connected to your peripherals if you have any connected.

Hope this solves your issue. Thanks for using FixYa.com.
