2009 Vizio XVT Series: 240Hz, USB input, LED backlight [NO PRICE TALK] - Page 168

Just yesterday my Vizio has started experiencing a significant problem anytime I access the Vizio on screen menu or use the Vizio remote.

Example using the volume control (but it could be any function)

1) Power cycles, Screen goes black for 10 seconds
2) Get "retrieving data" message
3) picture\\sound return to normal

Tested:

* Fail: Tried a different remote, same results
*

Pass: manual control buttons on Vizio function normally
* Fail: Disconnected Power for more 30 second, same results
* Fail: Disconnected all video inputs (only 1 HDMI in use), same results Addition problems:

When using remote(s), unable to get Vizio's on screen config menu to stay on screen. Menu stays on screen for 1-2 second, then the Vizio's power cycles.

Is there a way to do full hardware reset, restoring defaults, etc?

Here is a page that has a few "back doors" that might work:

Haven't tried any of them, but what have you to lose?

Good Luck!

thanks Big Jim.

It turns out I did not need to use that because the problem has mysteriously gone away. My best guess right now is that I had another monitor setting too close, or at odd angle that there was some interference between the two. The problem went away after I slightly moved the second monitor so that it was 2-3 inches further apart.

Hi all. I'm new to the forum and was hoping to get some help from someone that might have seen this problem before.

My Vizio VF552XVT started acting up recently and was wondering if anybody could give me some insight on how to fix it.
I took a video of it and posted it on Youtube, watch?v=mUeOD9f2Fg0

I know the link doesn't work but you should be able to figure out what to do with what I've given.

Thanks for any help you can provide.

I know it sounds simple, but did you try unplugging the set for a little while. That's the first thing I do if something isn't right on any of my Vizios. I also have a Gateway monitor that the backlight went completely out, unplugging it for 1/2 hour and it came back.

Just a thought.

I wish it was that simple. I've left it unplugged for days at a time with no change. It seems like the back light is working because you can see what appears to be shadows moving around.

My first guess would be the picture board but I'm not sure which of the 3 or 4 boards that would be.

I think that set had the audio as a seperate board, which is one of the smaller ones, the other is the power board, the one with the HDMI, etc inputs would be the video board I believe. I know that's what it is one the 553 and 554 which has only 2 boards in it. The audio is now part of the main board. There is a small 3rd board if you want to call it that for the LED control.

Do a search on the board part number, it should describe what it is. That's what I did with my 52" when the audio board went bad, got a new (used) one for 12 bucks on Ebay. Works great now.

So, which one of these boards would be the most likely culprit?

Where are the speakers? Try and trace the wires from the speakers back to a board. Is the bottom right board the one with the inputs on it? The long one on the left looks like it's for the backlight.

You might be able to find a description of the boards by searching with the part number on this site.

The one on the right is the main board.
The one on the left is the backlight inverter and the one on the top is the TV controller board according to Ebay descriptions.

I'm not sure whether to replace the TV controller board or the main board.

Link to Youtube video of the problem I'm having

I'm having service on my 554 tomorrow. I'll print out your pic and ask the tech.

After watching your video, to me it looks like it has to be the main board. Your not getting a picture or sound, is that correct? Does it do the same thing on all inputs? Your backlight comes on so it can't be that.

Does the 552 have a Vizio intro screen? I didn't even see that light up. I'm trying to figure out what to tell the tech when he comes. From what I can tell, the TV turns on, the backlight comes on but that's it. No welcome screen, no picture or sound is that correct?

My 552 displays a 'V' picture intro screen.

I have sound. No picture, only shadows.

The tech just left, replace all the boards in my set so I'll see what happens

As far as your problem he said it sounded like the main board causing the problem. The board with all the inputs on it.

That's good to hear, I ordered a main board from Vizparts yesterday.
Should be here on the 12th.

Then, it's just a matter of finding the time to swap them out.

I was finally able to get my TV fixed.
It was not the main board as I originally suspected but, the T-con board which is at the top of the picture I posted earlier.
Less than $50 from Tri State Modules.

Anybody still around reading this thread?? I have a problem thats started with my VF 551XVT that i've had since 2-10. Within the last couple weeks some very feint, grey streaks have appreared about a third of the way up from the bottom of the screen and from the the right side to approx the middle. There's about four of them, their vertical, not straight up and down but at a slight angle, kind of an arc about 2 to 4 inches long. At first I thought they were smudges from dusting the screen with a microfiber rag: their that feint. Of course I examined the screen with the set off and couldnt see anything. With some backgrounds they are not seen very well but solid color backgrounds especially white they really stick out. Another thing is that they seem to be more pronounced the longer the tv is on.
I'm really bummed as we've had nothing but a great time with this set! Anybody have any ideas??

Sorry to hear. Can't help but yes, you're not alone with the XVT out here. My 47" is still going strong @ 3 years old. usually replace at that time but trying to go 2 more years. Will keep this in mind should problems arise so thanks for sharing.

Sorry to hear of this problem. My 551 and my friends, both bought in Jan 2010, don't have that problem. (We were just commenting the other day that our 3-year Costco/Amex warranty was about to expire, and he was making a claim on a failure of two of his HDMI inputs.)

Can you post a picture of it? I have no idea but could it be a deterioration of a few LED lights behind that area?

I'm going to try to get a good picture. My first attempt didnt work so well. Maybe I'll use the snowy, white background of the x games: The lines were showing up pretty well.

I've got a stuck pixel on my panel. Tried tapping the dead pixel, unplugging TV, running a test pattern clip from the USB port, etc. I bought mine in the fall of 2009. Been great up til now. errr Can't take your eyes off that tiny green dot. Any other ideas to fix this issue?
