Well, it has happened again. I was watching a program, and the L75-A91 just went dark. The power light just flashes amber. I have looked at the error table, but since the light just flashes steadily and continuously, I have counted over 100, well beyond the highest value on the table. No breaks in the flashes and no other colors, just amber. I have tried unplugging and replugging, and I have tried the system reset described in the manual. No luck. When this happened last time, 2 years ago, a couple of weeks later the TV just started working again. I had called CPS (extended warranty), and they told me to do something, but it recovered before I did anything. I filed another claim tonight, as I still have a few months on the extended warranty (for what it is worth, which appears to be little judging from others' experiences with CPS—we will see). If anyone has any suggestions, I'd be most appreciative.
