Question about Vizio L37 Television

1 Answer

Small black squares appear on Vizio 37

Our TV has one or two black squares that appear in various places on the screen while we are watching. Sometimes there are none, sometimes there is only one, other times two but never more. They are about 3" tall x 2" wide, maybe. They are not there when the DVD is playing. We do have a cable box attached but have unplugged and replugged all the cables. It continues to come back. Any ideas? Thanks, Anne

    Same problem , but on a 42 inch Plasma and the squares are about an 1.5 in. tall by 1 in. wide and sometimes there are more than 2. Sometimes they go away and then come back again. Turning the set off then on again wipes them out for a while. Could this be a heat issue?

    I have the small black squares on my screen also this is a new problem. The initial problem is horizontal rolling just like in the old adjustable TV and now horizontal lines. Any ideas?

    I have the same problem, connected to a Comcast Digital Unit; and what I do is turn the remote to channel 4 instead of 3, and back again.....seems to solve the problem for a while

    I have the same problem. I called Vizio to figure out a solution but to no avail. I have the 42" LCD and it started with1 black square and within 48 hours there's 6 black squares. When I change the channel they disappear but come back in a minute or so. They don't appear while watching a DVD only TV.

    Same thing here on a vizio 42". Not a cable issue, all other tvs are fine. It started with one or two small squares last night, but now they have joined together to form longer blocks almost bars. Is this the first sign of the end of my TV? It is exactly 2 years old now. Same deal as everyone else, changing the channel temporarly clears the screen of the squares.

    I have the exact problem. I am with direct t.v. so no cable box here. My Vizio is 18 months old.

Sounds like a digital cable issue to me. Try connecting the cable directly to the TV bypassing the cable box and I bet that the issue will be gone. If so then contact your cable provider as the box or the incomming signal may be at falt.

Does the screen go black or does the screen turn off? To determine this, cup your hands place them against the screen with your face in your hands. This effectively blocks all other light out, if the screen appears to be lit even though it is black, the screen is still on.
If the screen in on but black, 1. Check the cables that are attached. If there are separate cables for the video and audio, make sure the video is properly inserted. 2. There is an internal problem with wiring. Check your warranty and try and return it or get it repaired.
If the screen is off, 1. The lamp is burned out inside the tv. This is usually a free fix if the tv is under 2 years old. Contact the establishment where you purchased it or the manufacturer for details.

Tv has black square in right bottom of screen

Hit the set up button on the TV.
You'll see options to change the language. The last option is to put the TV in "Demo Mode."
Put the TV in Demo mode, when the first screen appears, "Welcome to...." the PIP will disappear.
Hit exit before the screen moves to the "Menu." If you miss it, watch the demo once--it will restart--and hit the exit button the next time you see the "Welcome to" message.

Green Square appears on screen

Had same issue with my LG so I trouble shot the issue by noticing the green square would disappear if I switched to dvd(HDMI-2 ) Or HDMI-3. Which lead me to believe it was being generated by my Xfinity box (HDMI-1. So I first rebooted box. With no success I then unplugged box all together. Tah Dahhh! Problem fixed. Hope this helps.

Vizio 42" LCD - Random appearance of small black rectangles

There is a processing fault that is starting to occure. What you are seeing is a type of aliasing. This can be in the main signal processing or in one of the control areas.

The set will require service. The service rep will test the set by using board substitution. There are typicaly a number of areas in the TV set that can cause this type of fault. Once the defective board is located the fault will be easy to service with a simple board swap and some adjustments.

If the set is out of warranty, it may be expensive to service. With many of the no-name brands, spare parts can be difficult or impossible to have.

Black Rectangles on 42" Vizio HDTV LCD

Your DirecTV signal is probably too low. That would produce the small black rectangles (pixilation). Also, try replacing the cable you are using to get the signal from the DirecTV receiver.
