Your TV might not be having a proper connection to the internet and for the wifi and trying turning off other things that are connected to the internet and the wifi and see if that does help. Or Try turning the TV off and unpluging it for a few minutes too.
The audio is distorted for your TV or the settings for the sounds have become mismatched or the speakers are speakers are not working on your TV the fans might be broken with your TV and the TV is starting to malfunction.
Hi,
if removing all accessories from the tv along with a power cycle does not fix the issue, please perform a factory reset. Otherwise, you can setup a home repair appointment with Home Depot or Geeksquad/Bestbuy.
Thank you.
The cables might be loose or not connected tight enough or the cables need to be replaced or the screen has damage to it or the Tconboard is not working.The theexternal device might need to be repaired for your TV.
Most the time video issues are from the timing control board, if its the panel parts of the picture generally are missing, a common panel issue is black horizontal lines for one
Ebay has a refurbished main board for $67. Your Vizio may have cost about $800. And you are thinking about a $2700 TV?
If the Vizo died and went to heaven, would that prompt you to buy a $2700 tv? I don't see that the potential ***** of an $800 TV has anything to do with a decision to buy one that costs three times more. If something went awry with the $2700 TV, I pray you would use the warranty and not dive into its interior workings. My thinking is that if you are of a mind to buy a $2700 TV, you wouldn't mind spending $67 on ebay anyway, extend the life of the Vizio, and have two TVs. Nothing about the lifespan of the Vizio forces you to spend $2700 on a TV. If you paid $67 for a mainboard and installed it and it lasted three weeks, nothing would stop you from buying another Vizio. The only thing lost would be the dream of owning a $2700 TV. So, the question is can you live without the $2700 TV. And what would the purchase of such do to your budget as Christmas approaches. And would a $2700 TV make your life $2700 easier? Only you can answer that question.
The model would have helped. Generally horizontal lines in the picture come from a defective panel and the set isn't fixable, you could try replacing the t-con board but chances of fixing it are slim
If the LED backlight strips were new and you have all the connectors seated correctly it has to be a power board issue, or more specifically an issue with the inverter section of the board, remember its the B- section that is regulated not the B+, start by testing B+ to frame ground and see if you see 100+ volts on both circuits, next test the ripple, I've seen the inverter caps fail on this model a few times, other option would be replace the main board but I'd pull the panel out again and make sure all connectors are good, you can power the set up with the panel out but unhook the panel at the tcon not the panel to be sure the connectors don't short to the frame when it's powered up.
Hi,
Please double check that you've haven't used your remote to remove the display. Some remotes have a "visual mute" option. Also, please ensure that you're tuned to the correct HDMI input. If you accidentally changed it, you might have moved to an hdmi channel or state that has no input.
Thank you.
Hi,
Please plug your rca(?) plug into the corresponding color-coded plug(s) within your JVC device. And if those don't exist, then you can check for an amplifier plug.
Each cable should fit comfortable into it's intended slot.
Thank you.
This positively is a capacitor issue, when the caps are cold, they lose capacitance, if you put a blow dryer at the vents and warm the set up I'm guessing it will power on first time. I'd replace all the caps in the power supply section not just the ones that look or test bad
Your LED backlights most likely have failed and need replacing, it's a common issue with this and many other model LG sets, new strips can be purchased from shopjimmy.com for around $60
