Haier tv keeps turning on and scrolling threw channels by itself

that problem is on t-con board..try to replace it to come back your TV..

My TV 40RV525U changing channels, menus itself for few months ( I use antenna).
my son tried to stop the channel scrolling by enter weird number into the channel to stop it scrolling such as 555, 777..
later, it turn on off by itself and unable to hold on a channel
I call Toshiba customer service and they ask money $25 for troubleshooting but I denied since I do not want to waste money and time.

Now, I found how to fix it myself.

In my case, something was wrong with the signal comes from the button control on the left side of the TV.
========================
What I did
========================
unplug the power cord.
Remove back cover.
Look into the motherboard ( biggest green at the center).

First, I disconnect a connector on the motherboard come from the IR board that receive the wireless signal control ( meaning the remote is disable).
I turn on the TV, press on Menu button on the TV side. Menu is still scrolling.

I turn off TV, disconnect power cord and connect the IR connector back to the motherboard.
I then disconnect the nearby connector that comes from the side control buttons.

Turn on the TV by remote, press menu button on the remote to check. The menu stays.

DONE.

I use electric tape to seal off the connector and let it hanging there.
Close the TV back panel

I have been watching TV for 3 nights without menus/channels scrolling.
NO AVAILABLE red message when watching DVD is no longer existed.

Hope this help someone else.

Hello mrdavidmetca,

Welcome, and thank you for using FixYa!

I would start by pulling the batteries from the remote control. Manually turn the TV off and then back on, manually. If the issue resolves, replace the remote.
If the issue continues; you will need to find a local TV Repair Shop and have the Tuner Board replaced.


Have a great day!

right side push button stick ...check and open stick button

I have this same problem with channel 5-1 Los Angeles anyone have any advice?

IC pin is dry in Micropro. IC

I have a 32 in. Haier also, i believe channel 3 should do the job but not sure cause i got mine hooked up threw the comcast digital box and hook it up to my tv threw the video inputs. I was told you get better picuter doing this thats why i got mine hooked up this way.

Sounds like it has one of two problems first one could be a stuck button. The micro locks up and the set wont come on also could be causing the channel scrolling run you finger along the channel buttons. Other than that you would need a new signal board you have a locked up micro...this part will be No longer Available.

Plug it into a power strip and turn off the power strip as well as the TV. I've been told that newer TVs are always "on" - standby mode- and someone probably has a device somewhere in the near vicinity that is turning it on. (Or your cat is watching it when you're not home.) Or you could just unplug it when you leave.

You probably have a bad channel down switch on the TV. This is common if any kind of liquid spilled inside of the TV near the controls. The other possibility is just a stuck button on the control pad itself. Sometimes the plastic warps a bit causing to rub against the cabinet causing it to stick. Try moving the button and see if it has free movement.
