If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

That sounds like a fault code coming from your Plasma. Some of them have alarms that go off when say it's overheating, Fans don't turn, the panel has sensed a crack in it. These are random as I don't have the fault code for that particular model. There is a reset sequence of buttons while you turn it on to reset the alarm. I would contact the manufacturer. to see what those fault codes mean. If something minor you can do the reset alarm and watch for a short 2-3 hrs. but will need to be taken in to be serviced. If you can reset it and turns on then you know your power supply is good.

According to the manual for "POWER/STANDBY indicator is blinking in red":

• "The temperature inside the main unit has become too high and has activated the protector."
• "Promptly switch off the power of the main unit ans wait until the internal temperature drops."
• "If the monitor becomes too hot, the overheat protector will be activated and the monitor will be turned off. If this happens, turn off the power to the monitor and unplug the power cord. If the room where the monitor is installed is particularly hot, move the monitor to a cooler location and wait for the monitor to cool for 60 minutes."
