Alright the TV does power up and the only things wrong with it are the very loud buzz in speaker and no OSD( on screen display). I hooked up my Sega Genesis and with the remote or buttons on the TV was able to tune to channel 4. Here is video showing what is doing https://youtu.be/qa7LNQ5cB74?is=Zjf09przu7eA16gI.

I guess if worst comes to worst just unplug the speaker who needs sound anyway

Do you get any real audio at all, or only buzz?

If the answer is some audio plus buzz, does the buzz track with the tuning, or is it constant, even if you manipulate the fine tuning or touch the antenna leads?
