I am a bit of a blockhead with computers;however I am attempting to fix this elephant. It was given to me as i, the owner claimed as he was working on it- dropped a screw and the convergance issue was no longer a issue. I power up and it remains red, press menu and a odd sequence of 4 or 5 flashes occurs. The heaters do not glow and a soft chirp from the speakers occurs- there is a suitable power draw that occurs upon plug-in. Thanks to anybody with advice.
