Does anyone know why a Sony 270ES would turn itself off during operation, followed by the warning light flashing red continuously? PJ is about 22 months old with c.700 hours of use. Never happened before. I was about 80 minutes into the film. After waiting a minute or so, I turned the PJ back on and was able to watch the film to the end. Nevertheless concerned that it has developed a fault. Grateful for any insight.
