Hi,

I have an old Hitachi TV, model CT2043B. The internal speakers have been
turned off in the settings, and I want to turn them back on. The thing
is the remote "Sound" button does not work anymore. I tried universal
remote controlers, but they don't support the "Sound" button, only the
"Menu" button. I prefer not buying a replacement remote as only the
"Sound" and "Picture" buttons are not working on the original remote. I
did try to clean it with no luck. Is there any way to reset this TV
setting to the factory default?

Thanks
