When you turn the tv on, it lights green and tries to turn on, but does not. The green and red (on/off) lights are on simultaneouly, and every few seconds youcan hear it try to come on.

I repaired a lot of these sets when they were new and under warranty.

The most likely reason for 'shutdown" which is what you are describing, is one of two parts.

The "Flyback" or High voltage transformer in these sets fails; usually with back off when you try to turn set on you see a little arc at top of high voltage transformer---means it is bad-----so common I have literally replaced dozens of them.

The second common (not as common as the transformer) reason is there are a number of special capacitors right around the same area as the transformer; they do not short or burn---they open like the filament in a old style light bulb----a little tricky to find but not expensive.

The Flyback transformer is black with a large red wire coming out of the top that goes into the picture tube; part may be found on internet for approx 50 dollars or Loewe parts center for 75 plus.

Everything about these sets was expensive; I still have 3 brand new remotes for them--wholesale on them about 85 dollars.
