I just happened to me too, with Hitachi player .. same date. Are normal Trinity but give few problems if, for example, do not you power off the console, then letting them live the night or long periods, for example, start giving red light!
Unplugging the power for a few seconds and reconnecting power to the console, and works perfectly for the hour .. even days.
Although I always use the 3.3V alternative that keeps the CoolRunner switched off when the console is in stanby.. It is not a unique case, a single console, but all the ones I changed to that date, the same player Hitachi etc.. all 4 Giga Slim are sold by Mediaworld .. I have taken under a 15 console to date.
