Hi, A month ago I have bought a 48 inch samsung curved TV model UA4J6300. From lat week I noticed that while playing file from USB i can't able to go previous menu by pressing "return" button. Also can't play a file by pressing "Enter" which was working previously.
Now facing problem while using this TV. Please advice how to solve. I have already tired by resetting the TV and also by factory restore.NO RESULT.
