I have a 1980-era Mitsu VS-457RS television that has failed. There is a red LED which lights on the front panel, but it acts as if it has no power otherwise - There is no screen or sound.
Strangely, this happened before, but it started working again after being left unplugged for a couple of weeks. It continued to work for over a year.
I have done repairs on arcade monitors, so I'm comfortable with replacing flybacks and capacitors, but I've never been inside of a big screen. Web searches have turned up almost nothing on this model.
Any hints on where to look for info or what to expect when I crack it opened are appreciated.
