It is set to TV
It is a Samsung LE228541c
Hmm, your TV software may have a software glitch in it. Let's reset the TV with the Plug and Play function on it. It's in your menu too, and if you are not on the TV input, the Plug and Play function will be grayed out, and inaccessible.
Im really not explaining myself too well
the Menu button doesnt function, it brings up the message 'not available'
this is the correct remote
it was unplugged for some weeks
Ok, you've tried to reset the software/firmware and did a hard reset to the TV's main board but none were successful.
You need to replace the main board to restore normal operation, so you'll have to remove the TV's rear cover screws, lift the cover off, and look at the main board's stickers and verify the BN number on it.
You can also check your main model number which has EXTRA letters at the end that verifies the model and part number of the main board matches.
Here is a website that sells the main board --
Copy and paste that into your web browser. You'll see a picture of the part, along with the full extended model number and the BN number they print on a sticker found on the main board.
I always prefer to look at the main board to verify the actual board installed on the TV set. That number is XXXXX most correct and concise number to order parts with.
Here is some more detail about the part number on the main board.
