Am currently working on this set. Symptoms are tries to switch on from standby, led goes blue and a relay click is heard. After a few seconds set goes to standby with front standby led flashing red 3 times -pause cycle. There is no sign of picture or sound.
All power supply voltages are healthy. Checked SMD fuses on main board but again nothing wrong found.
Have read this forum for related faults but haven't seen this model mentioned. Could be the Seine board that is not booting properly. I have cold checked the LED driver board for any shorts but everything seems good.
Was trying to opt for a firmware upgrade. Am aware that can do from standby but don't know the procedure. Most probably its a flash using a dedicated jig not from usb. But there again I might be mislead.
Anyone got a service manual willing to share?
