On my Hitachi 50UX26B the only button that is working is the power. Neither the remote or the buttons on the TV will change channels or volume. Today it also has a wide black strip in the middle, about 24 inchs wide. Can only see picture on each side.

Look on the TV for buttons for power, volume up and down, channel up and down and menu.You can get a new factory remote from here :

Most likely the buttons on the tv are stuck or malfunctioning, replacment of the button pannel will solve the issue

any universal remote would work but hte hitachi remote for that model is expensive i suggest buying a logitec harmony universal remote for around 40 bucks from amazon. you plug it into you computer and just type your model number in it will install all the original options to this remote plus allow extra features such as activities where it can change the channel on your tv and turn your cable box on and let you change volume on your sound system without the hassle of having to use different remotes. and without having to hit different buttons i.e cable button to change channel and tv button for remote it will do it automatically

Try to replace the remote control with a new one. If it doesn't work, then there is something wrong with your TV.

There should be buttons somewhere on the TV itself to switch input modes. Look around where the power button is located and see if there is a menu button you can access. Then use channel up/down and volume up/down to scroll thru modes to find input

Hope this helps

Is the front funtion button works in the TV the it could be a bad remote controller(the button switch inside) :)

Good Day;

To reset the TV unplug power cord from the wall for 2 to 5 minutes then plug back in.

Good Luck, big IRISH.

I had exactly the same problem. I finally found the power button on the underside of the TV. It is well hidden and to find it, you need to run your fingers underneath the panel. Turn it off for a minute or so and turn it back on and then turn on the switch on the panel on the upper right side where the channel and volume buttons are. It works.

Will not turn on. TV is pluged in its almost like a power surge. The power bar is lit so for some reason the tv is not getting power.

Well there is still a problem with the TV. I found that by unplugging the power cable that the digital channels worked. But, when I turned the TV on today the problem had returned, I had to take out the power cable again!
