Hi folks,
Just had three TX-L32/37E3Bs and a TX-P50X50B in for the issue where an over air update has maybe zonked them giving a flashing Green Led and nothing else.
Seems holding in S/by switch and holding in another on the set (Seems to vary a bit) for a few seconds, normality is resumed. Turned off 'updates' as someone suggested - Bit of an earner in these hard times - Chris.
