How to get a schematic & pictorial for a Vizio XVT3D47SV

The unit turns on, the display lights up, but the picture has a "Kaleidoscope" appearance, that is the colors are scrambled in a contour map fashion. I can't locate a pictorial or schematic for the unit anywhere to find out where the main video processor board is located. When the unit first started failing it had the appearance of a heat related failure in that I turned it off for 2 hours and the picture appeared normal for an ever shortening time before the kaleidoscope appearance reappeared until the kaleidoscope was permanent. Maybe if I had attacked the problem with freeze spray early on I could have located it, but now it appears I will have to dig deeper into it

Is your grey scale or Black and white programming pink?? Thats an indication that the green and blue grids on the picture tube are week or that the red is over driving. First thing is take off the back of the set. Find the end of the picture tube and look at the printed curcuit board there. see if you can find and red drive controls there. Put on a black and white pic and ever so slowly rock that red drive control a little at a time till the picture looks almost normal.. If you get it to be a little \less pink then stop right there but if it starts to get a bit green or blue then try rocking those controls all back and forth till you get the bese B&W picture you can BUT BE VERY CAREFULL as there is alot of voltage on this picture tube and if your not carefull it will bite ya. Now dont be too critical as the tube is a bit weak so you probably wont get a perfact grey scale so if after a while live with it or get a new set. Good Luck.

You can purchase a variable power supply that will light this lamp and control its intensity if you determine that the power supply in the microscope is bad. This may be the easiest way to fix the problem. Parts for many older microscopes are no longer available and this is a common way to repair the microscope. It's also a common modification made to many laboratory instruments for research purposes. Carefully check the lampsocket as well. It's common for them to fail and replacement is the only cure. The lamp socket is not expensive.

Hello, This seems more like an interface problem then a board issue. Which interface are you using Component Video, HDMI or , RF(F Connector)? If you are using the RF (F Connector) there might be a problem in the tuner including the RF and IF sections on the circuit board. If you are using HDMI there might be a problem in the HDMI Integrated Circuit If you are using componente video the there might be a problem in the video circuits connected to the RCA jacks of the Component video input. If I were you I would have the take the TV back to the shop and have these items checked out, because board swapping is not the proper thing to do. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

I Have a ViZIO smart TV Model # E420i-Ao Ser# LAQKNRBP0500931 has sound but no picture No light show up in the back and can see any thing on the screen with flash kite when you push channel or menu


It is a common problem for Vizio TV uses a LG 42" & 47" display panel.
The problem is defective back light LED strips, you have to open the entire panel & find the defective strips (it marked as L1, L2 (left), R1, R2 (Right)), the part number usually marked as 6916L-XXXXX.
Both Vizio & LG will not sell the strips, you have to find them on EBay for new or used one.

I'm building a Kaleidoscope with internal lighting. I have the lighting worked out with a switch, but I would prefer it to turn on with a sensor that detects when the kscope has been picked up.


For a non-powered solution, you could use a tilt ball switch from Adafruit to turn on the kaleidoscope when it is picked up: https://www.adafruit.com/products/173
This will only keep the kaleidoscope on while it is held in a certain position.

You can also add a flip-flop latching timer that is activated when the tilt ball switch is triggered. The kaleidoscope would then stay on for a certain amount of time. I found this on eBay, but have never used this one: https://www.ebay.com/itm/262578744921

Hopefully this helps or at least gives you some ideas. :-)

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.

The LCD screen is dark with no sound or picture when turned on.


I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

What your tv repair man needs is a Parts & Service manual you can find that here..

http://www.justmanuals.com/advanced_search_result.php?keywords=vizio&osCsid=oi9vp9i6nntk7a6rebllgcsgt3&x=0&y=0

The Manual will have the schematics and block diagrams..

If your repair man needs you to find this info, then maybe you should find a new one?
