Question about Vizio Televison & Video

1 Answer

Hey everyone! I have a 2018 Vizio E75-E1 television. I was watching it about a month ago, when suddenly the screen froze and gradually went black over about 45 seconds. The tv does power up. It does have a backlight. It has no image regardless of source (not even the menu). I don’t know about sound because I never used the onboard sound and think I had it disabled in the menu (which I can’t access). I replaced the TC board, power board, and main board. The results are exactly the same... powers up, backlight, no image. I’m suspecting the panel is dead, but figure I would toss this out there anyway. I haven’t replaced the led boards, but don’t see a need as they all light up. And I was not suspecting the power board either. I just replaced it because it was cheap. Thoughts?

SOURCE: Dynex DX-PDP42-09 Won't power up.

Hello
The main board is faulty. This is the common problem to most of the dynex TVs. As you know there is no repair to this board. Replace it as card basis is the only remedy to this fault.

gopakumarg43_84.jpg Replace this board, rather than making surgery to it and wasting your precious time and money. The cost of the board come around $95. OK.

SOURCE: LCD TV Has Sound, Backlights Work, but No Picture

I have been having the same problem with my LG. people say there are bad capacitors on the power supply board. I don't have the know how to replace them and don't have the money to pay. I can get mine to work by blowing hot air with a hair dryer into the back of my tv through the vents over the board. Heat it up for a couple minutes and turn it off and then back on and the picture comes back. I just never turn the set off now.

SOURCE: Vizio m550nv backlight won't work

This TV comes with a remote that connects to the TV via Bluetooth. It remembers which equipment is connected to the various inputs, and automatically changes the controls to match the input equipment - really nice! I found that it will control all my equipment, and since it works via bluetooth, you don't have to have direct line-of-sight to the TV. Wish that the bluetooth part worked for my satellite equipement too! Programmable remotes will operate this TV, but depending on how old they are, they may not be able to hit all the features of the tv - our older directv remotes will operate the basic features, but only the newer models will change the input source - so you may want to use the remote that came with the TV. We have smaller kids, and wanted to limit their use of the tv remote, because it has a slide-out keyboard similar to those on some cell phones to make posting to facebook (one of the apps that comes on the tv) easy. Since our youngest is 5, we thought it might be best to keep that remote out of harm's way.

42in Vizio black screen, no sound


I had the same issue happen to my vizio lcd just this weekend. Everyone is telling me is a bulb or backlight or something. It would explain the loud pop and no picture, but I'm not getting sound either so I'm not sure what exactly happened. Only after about 2 years too. I'm trying to find parts to just fix it myself.

Front panel blocked or locked


RCA Entertainment Series 32" Plus Gold, GEMSTAR, xbox ready has been in the shop twice so far. Transformer replaced and 6 months later the picture suddenly had horizontal white lines that gradually spaced apart more from top to bottom and it had a gray hue and fuzzy, but I still watched it for 3 months that way. Today I turned it on and about a minute later I heard a loud crackling sound coming from the back and the picture disappeared, screen went black. Is it worth fixing again?

VIZIO BLACK SCREEN


That problem is the Ysus board, Sometimes people will replace the Zboard at the same time. If you bought it at costco a couple of years ago you are in luck costco will refund your purchase price, costco has changed the return policy and newer tv's are not refunded, but something to look into
