If your Denon AVR-888 is not passing HDMI signal from your Asus UX431F laptop to your Vizio TV, but is passing signal from your Apple TV, there may be a compatibility issue between the laptop and the receiver or between the receiver and the TV. Here are a few things you can try:
Check HDMI cables: Make sure all HDMI cables are properly connected and working. Try using different HDMI cables to see if that resolves the issue.
Update firmware: Check if there are any firmware updates available for the receiver and the laptop. Updating the firmware can sometimes resolve compatibility issues.
Check laptop settings: Make sure the laptop is set to output video through its HDMI port. On some laptops, you may need to manually select the HDMI output in the display settings.
Try a different input: If your receiver has multiple HDMI inputs, try plugging your laptop into a different input to see if that resolves the issue.
Contact the manufacturer: If none of the above steps resolve the issue, contact the manufacturer of the laptop, receiver, or TV for further assistance.
It's also worth noting that some older HDMI receivers may not be compatible with newer HDMI devices. If your receiver is several years old, it may not be able to pass the HDMI signal from your laptop. In that case, you may need to upgrade to a newer receiver that supports HDMI 2.0 or higher.
Chances are you have main board issues, a replacement board should fix the set. Shopjimmy would be a good place to buy a board, not the cheapest but in most cases the boards from there are working verses a 50/50 chance of a good board from ebay sellers
Hi Alon, as you say, it would be very possible that the main board is responsible for the malfunction of your Vizio TV
Because you say you have no image, no sound, assuming you turn it on knowing what input it is and there is some ymagen and sound, but the TV does not show you anything
If you were to have sound, there could be the T-Con board, since this does not affect the audio
I hope you can solve the problem
Greetings Franco Dosil
Hola Alon, por lo que comentas, seria muy posible que la placa principal sea la responsable del mal funcionamiento de tu TV Vizio
Porque dices que no tienes ni imagen, ni sonido, suponiendo que lo enciendes sabiendo en que entrada esta y que ah? hay alguna imagen y sonido, pero el TV, no te muestra nada
Si llegaras a tener sonido, ah? podr?a ser la placa T-Con, ya que esta no afecta el audio
Espero puedas resolver el problema
Saludos Franco Dosil
If your Vizio M656-G4 TV is not powering up and there is no standby light, here are some steps you can take to try and resolve the issue:
Check the power source: Make sure the power cord is securely plugged into the wall outlet and the TV. If the power source is a surge protector or power strip, try plugging the TV directly into the wall outlet to rule out any issues with the power strip.
Check the remote control: Make sure the batteries in the remote control are fresh and properly inserted. Try using the power button on the TV itself to turn it on in case the remote is not working properly.
Perform a power cycle: Unplug the TV from the power source for at least 60 seconds, then plug it back in and try turning it on again.
Check for firmware updates: Make sure your TV is running the latest firmware by going to the settings menu and selecting "System," then "Check for Updates."
Contact Vizio support: If none of the above steps work, contact Vizio support for further assistance. They may be able to provide additional troubleshooting steps or recommend a repair service if necessary.
It's worth noting that if your TV is still under warranty, it may be best to contact Vizio for assistance as attempting any repairs yourself could potentially void the warranty.
What's the model of your TV Martin? I have a feeling you have a bad panel but can get you more info with the model, if a tcon didn't fix it and you cleaned the connectors and they look ok, no bent pins or missing pins I doubt new ribbon cables will help.
If your Vizio M502i-B1 TV is not turning on despite the power board, fuse, and power cord being in working order, you can try the following troubleshooting steps:
Check the remote: Make sure the batteries in the remote control are fresh and that the remote is functioning properly. Sometimes, a malfunctioning remote can prevent the TV from turning on.
Unplug the TV: Disconnect the TV from the power outlet and leave it unplugged for a few minutes. Then, plug it back in and try turning it on again.
Check the input source: Make sure the TV is set to the correct input source. If the TV is set to an incorrect input, it may appear to be turned off.
Check for lights: Look for any lights or indicators on the TV that may be on or flashing. This could indicate a specific issue with the TV that can be diagnosed and resolved.
Contact Vizio support: If the issue persists, you can contact Vizio customer support for further assistance. They may be able to help diagnose the issue or recommend a repair service if necessary.
If none of these steps resolve the issue, it may be best to have a professional repair technician diagnose and repair the TV.
Try a reset, unplug the TV, then press and hold the power button ((on the TV set)) for 30 seconds, then release it. Then wait 10 minutes and plug the set back in, press and hold the power button again on the set until it turns on.
You have an edge lit tv, most sets have several strips of LED lamps but this model has one row at the bottom of the panel and uses a defusing screen to spread the light. You have three possible issues, you said you had the set apart and replaced the LED backlight strips, did you tape the defusing plexiglass and screens together so you know what order they go back in, they need to go in the correct order if they get mixed up the bottom will be brighter, if the plexiglass isn't all the way against the back of the frame it will cause the light not to be spread to the top of the screen the way it should, the last possibility, and I think this is the issue from what we're found at our repair shop, when the individual backlight lamps burn out it puts more voltage on the working ones and can melt or warp the defusing plexiglass, this makes the bottom brighter. In most cases we're found the defusing screen needs to be replaced after the LED light strips are replaced.
If you have already replaced the power supply board and your Vizio TV still does not turn on, there may be other issues with the TV. Here are a few steps you can try:
Check the power outlet: Make sure the power outlet you are using to connect your TV is functioning correctly by plugging in another device.
Check the power cord: Inspect the power cord of your TV for any damage or loose connections. If the cord is damaged, replace it.
Check for blown fuses: Locate the fuse box in your home and check if any of the fuses are blown. If a fuse is blown, replace it with a new one.
Try a different remote: If you are using a remote to turn on the TV, try a different remote to see if the issue is with the remote.
Contact the manufacturer: If none of the above steps work, it is best to contact the manufacturer or a professional TV repair service for further assistance.
To program a Vizio TV with the Greenbrier International 110064 Universal 6 In 1 Remote, you can follow these steps:
Turn on your Vizio TV.
Press and hold the "Code" button on the remote until the LED light stays on.
Use the number buttons on the remote to enter the code "11864" for Vizio TVs.
Press the "Power" button on the remote to see if the TV turns off. If it does, press the "Enter" button to save the code. If it doesn't, repeat step 3 with a different code from the list below until you find one that works.
Other possible Vizio TV codes for the Greenbrier International 110064 Universal 6 In 1 Remote include:
11758
11756
11742
11740
11738
11687
11670
11587
11365

Note: If you can't find a code that works for your Vizio TV, you can try the auto-search function on the remote. To do this, follow steps 1 and 2 above, then press the "Power" button repeatedly while pointing the remote at the TV until the TV turns off. Once it does, press the "Enter" button to save the code.
If you have checked and confirmed that the voltage at the PS_ON pin does not change when hitting the power button, it is possible that the main board (756TXBCB2K013) is the faulty component. The main board is responsible for sending the signal to turn on the power supply board (ADTVA2419XYG).
You may want to try disconnecting the main board from the power supply board and then pressing the power button. If the voltage at the PS_ON pin changes, then it confirms that the main board is faulty. If there is still no change in voltage, then it is possible that the power supply board is faulty.
Alternatively, you can also try checking the capacitors on both boards for any signs of bulging or leaking, as faulty capacitors can sometimes cause issues with power supply.
There could be several reasons why your Vizio sound bar is flashing standby and powering down. Here are a few things you can try:
Check the power supply: Make sure that the power supply is properly plugged in and that the outlet is functioning properly. You may also want to try plugging the sound bar into a different outlet to see if that resolves the issue.
Check the remote control: Ensure that the batteries in your remote control are fresh and that it is working properly. Sometimes, a faulty remote control can cause issues with the sound bar.
Reset the sound bar: Try resetting the sound bar to its factory settings. To do this, unplug the sound bar from the power source, press and hold the power button for 5 seconds, then release the button and plug the sound bar back in.
Check the connections: Make sure that all cables are properly connected to the sound bar and any other devices it may be connected to. If you are using HDMI cables, try using a different cable to see if that resolves the issue.
If none of these steps work, it may be necessary to contact Vizio customer support for further assistance.
It could be either bad LEDs or a faulty driver board. If it is only 1/2 of the LEDs that are pulsing, it's likely that the LEDs may be starting to fail and need to be replaced. If the issue is only with a few LEDs, then it may just require some maintenance to get them back working properly. If the issue is with the entire backlight, then it is likely the driver board and will require a replacement
