Hello , my name is Jack

hello
Expert:  Jack replied 1 year ago.

Thanks , a few questions first ;

Customer: replied 1 year ago.
okay
Expert:  Jack replied 1 year ago.

You said that you are using the tv as a monitor , what is connected to the tv ?

About this message , this appears only when using the remote ?

What about the buttons directly on the tv , do they work ?

Customer: replied 1 year ago.
my computer
Customer: replied 1 year ago.
the tv's buttons do not work
Expert:  Jack replied 1 year ago.

O.k and how is it connected to the tv, hdmi or vga ?

Expert:  Jack replied 1 year ago.

Can you give me the model number of this tv ?

Customer: replied 1 year ago.
the message shows up when the tv is on
Customer: replied 1 year ago.
model number: 26lh20
Customer: replied 1 year ago.
vga
Expert:  Jack replied 1 year ago.

o.k , i`ll need a couple of minutes on that and in the mean time , try to pull out the power cord 30 secs or so and try it again ?

Expert:  Jack replied 1 year ago.

got anything with that reboot ?

Customer: replied 1 year ago.
no
Expert:  Jack replied 1 year ago.

O.k then I need to make sure of something here ;

The buttons on the tv are completely inop , is that correct ?

When does that message appear " This function is not available now " , is it when using the remote or the buttons on the tv ?

Customer: replied 1 year ago.
the buttons are inop, but the volume button will work if I hold it down for a while and then the message we go away, but once I let the button go then it comes back
Customer: replied 1 year ago.
at one time the remote did work when the buttons did not, but now even the remote is useless
Expert:  Jack replied 1 year ago.

O.k then the buttons are somewhat working if you press hard enough , which would indicate a defective control /button board and then about the remote , is that where you get that message ?

When trying the remote or is the remote dead as well ?

Customer: replied 1 year ago.
it's not a pressure issue, I just hold it down for a few seconds an then the volume will go up or down, but no other button works like that, just the volume button
Customer: replied 1 year ago.
the message comes on when the tv is on no matter what I do, as for the remote it has no effect on the tv's function
Customer: replied 1 year ago.
right now the tv is on but there is no power light showing that it is on
Expert:  Jack replied 1 year ago.

No problem it just looked like an issue where the touch buttons get worn and need more pressure.

Reason for asking all of this is because this tv has a function that allows you to lock the buttons directly on the tv so that message could be part of this although this is a bit confusing now as it seems like it works after a few seconds and the volume only .

Let me resume this then

Customer: replied 1 year ago.
how do you lock and unlock the buttons?
Expert:  Jack replied 1 year ago.

If the tv is indeed in lock mode then you need the remote to get it out of that mode but rght now it looks like the remote is dead .

What were you using the last time it worked correctly and before contacting us , was it the remote or the buttons on the tv ?

Customer: replied 1 year ago.
I was using the remote to turn on and off the tv, just this morning
Expert:  Jack replied 1 year ago.

lock /unlock is this ;

Expert:  Jack replied 1 year ago.

Do you happen to have a cell phone camera,digital camera or any camera that has a display or screen to test the remote ?

Customer: replied 1 year ago.
I have a cell phone camera
Expert:  Jack replied 1 year ago.

O.k then here is how to test your remote;
Turn on the camera and point the front of the remote at the camera lens ,then while looking at the remote through the screen press buttons on the remote.
If the remote is working, you should see light coming out the front of it while looking at it through the camera screen.
If you see nothing coming out and are not sure if you did the test correctly then try it with a known working remote.
You can look at the link below to see an example;

Customer: replied 1 year ago.
I just used the remote to turn off the tv then back on
Customer: replied 1 year ago.
key lock is off
Expert:  Jack replied 1 year ago.

No problem with that but you are saying that the power button doesn`t work on the tv ??

Have you tried holding that power button like you do for the volume ?

How did you get in the menu right now ?

Customer: replied 1 year ago.
I used the remote to get into the menu
Expert:  Jack replied 1 year ago.

o.k so the remote is working now ??

Customer: replied 1 year ago.
as for the buttons nothing is working
Customer: replied 1 year ago.
no, I just tried to use it to change the channel and that message popped up again but it's now off
Expert:  Jack replied 1 year ago.

O.k then you mean that your original question no longer stands and its all working now ??

Did you restart / reboot the tv earlier as I suggested ?

Expert:  Jack replied 1 year ago.

You can`t change the channels is the tv is in vga mode , hence that message

Customer: replied 1 year ago.
I unplugged the tv for more than 30 sec and then plugged it back up and still getting the message and the button along with the remote are not working
Expert:  Jack replied 1 year ago.

You can`t change the channels if the tv is in vga mode , hence that message

Customer: replied 1 year ago.
the volume is not working as well
Customer: replied 1 year ago.
hold one sec please
Customer: replied 1 year ago.
the computer cord is plugged into the RGB slot on the back of the tv
Expert:  Jack replied 1 year ago.

No problem with that if you have a pc connected to it , why would you want to change the channels then ?

Expert:  Jack replied 1 year ago.

You said earlier that the volume was working if you held the buttons

Customer: replied 1 year ago.
I was only doing so to see if the tv would respond to the remote
Expert:  Jack replied 1 year ago.

Do you use the pc`s sound card volume or the TV's volume and right now I`d like to know what it is that doesn`t work normally ??

Expert:  Jack replied 1 year ago.

I`m going to repost your question now .

You don`t have to do anything , your question will be reposted for other techs. to see and jump in.

Customer: replied 1 year ago.
I only use the computer and subwoofer system for sound
