Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. ..

Try pressing the channel down button repeatedly until the lowest channel is displayed. Now keep going to see if it changes to an external port like F1 or R1 If that won't get you a picture try going to shopjimmy website to get a new remote.

disconnect from the mains and turn it back on, it sounds like its just crashed it happens sometimes

This is a common complaint. To be frank I don't have the exact term for your Vizio, but most recent LCD and plasma TVs have the ability to "zoom" or adjust "picture format" (those are two commonly used terms) depending on the signal source and format.

it has to do with the fact that currently there are both classic style format 4:3 signal sources as well as new HD 16:9 signal sources and on top of that it may happen that a 4:3 signal source is distributing adjusted image from a 16:9 or other signal source. Think cinema adjusted to run on classic TV - remember the vertical strip of image with two huge black areas below and above it?

Well the ZOOM or PICTURE FORMAT allows to adjust such an image so that you cut the "void" are by scalling (enlarging) the visible area to fit the whole screen.

A problem then appears when the signal source is normal and showing full screen. Then, because of the enlargement, you start missing some of the picture. Before there was nothing there because it was showing adjusted wide (cinema) format to the TV box format, but when the new TV box format gets enlarged it sure starts missing around the edges.

That's what you're seeing.

More and more TVs do not have the ability to adjust that through the TV itself. Don't ask me why, but they can only do it through the remote.

So if you have an original remote there MUST be a button there that's called ZOOM or FORMAT.

It does the trick.

Hope this helps. If it does do not forget to rate it.

Your Direct TV box is switching between a Standard Definition channel and a High Definition channel. When this happens, the TV has to switch the display format. As the format is changing, you will briefly loss picture, the TV detects the new format, and then displays it. What you are seeing is the normal operation of the TV. It the TV did not blank the picture, you would see a broken chopped up picture during the transition. If you are familiar with the setup menu of the Direct TV box, you could change the video format settings so than it locks to the High Definition format. If you are not familiar with the Setup menu, you should contact Direct TV and ask then to walk you though this procedure. Specifically, ask them to "Help me set my Direct TV box so that it always displays in 1080i format." You pay for them for the service, they should be able to provide you with some phone support at no charge. I hope this was helpful, best wishes.

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

I have HLN 5067wx after replacing the color wheel and inserting new lamp There is sound withou the grinding but absolutely no picture; What is going on?

This problem is normally the Vertical filter capacitors. You need to have them changed before it burns out the Vertical Chip.

Good Luck

The problem might have started because of loose conections in the vertical circuit,if the vertical circuit fails completly the screen blanks out to prevent a line being burnt in the picture tube so that part is normal but the problem is still in the vertical circuit.Maybe the IC just went bad all the way and it might have taken a fusible resistor. If you are familiar with tv service you have a place to check but if you are not too familiar be safe and call for assistance from a servicer,is a straight forward problem and it should not be expensive.Let US know how it goes or if you need more information.
