Try taking the batteries out of the remote. The channel buttons may be sticking.

Wont stop changing channels


Check and replace the main system memory IC. It is faulty. It is a very small IC, won't cost more. An eight solder terminal IC. Even though the physical size is small, function to it when the TV works is great. The work is a skilled one.

Is it going one way - channel 1-2-3-4-5 bottom to up or any way at random. Find out which way and check the channel button on the TV to see if it is stuck.

My tv randomly turns on, and changes the channel... i have tried everything to get it to stop and cant, and now it just goes between channel 3 and 44 randomly


Hi my name is Roety,
I can help you with your issue ,
You either have a stuck button or a bad main board.
Running the autoscan / autoprogram with a good signal sometimes locks the TV processor to the received channels only.

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.

Channel changes automatically


There are a few things that can cause this. #1 most often cause is either something spilled on the channel button or something wrong with the bezel where the buttons are located causing the button to be pressed all the time. Check the buttons on the tv and make sure none of them are stuck. #2 is a bad button (switch). Replace the switch or the control board. #3 is a short on the wiring harness going from the switch to the mian board. Maybe it's squished against the frame somewhere. #4 would be a bad main board. You will likely have to take this unit to a service centre to have it looked at.

Turn tv on, and it scrolls through the channels


Had the same problem, channels would not stop scrolling.
It was as though someone had there finger on the channel up button.
Disconnected the sixth wire, starting with the black wire on the wiring harness for the front buttons, on/off, ch. up/down, vol. up/down, etc.
It works fine, no more unwanted channel surfing!!
