I have the same issue too, after auto upgrade to 4.5.2 still have only sound, no picture in the beginning, after about 3-4minutes, the sound was gone too, what i have is just a black screen with no sound. But if i switch to another channel and switch back, the sound will be back on, after 3-4 minutes the same issue happen again. Anyone can solve these issues? Thanks.
Sorry for the typo. I meant to ask how you install the apk file to the htv box, and whether if we need to uninstall the current app from the box before installing the new apk? Thanks.

Since you are downgrading then you would need to uninstall it first.
