I know there are two more guys on here with same problem but no the 46" model they actually share the same internal components
My problem is powered tv on power light is solid green for approx 2 minutes then flashes green at rate 1 per second like forever
Being a LED backlit set there are no invertor boards which this would probably suggest.
Power board shows 13v from 4 pins on PD going to main board. There is 12v missing from PL going to T CON board which I assume is switched by signal from main board etc.
Now the main board has two small red flashing diodes which I assume would normally flash green after firmware did its thing
Can anybody shed light on this like is there anyway to rule out main board failure or power board failure (component) or software problem
Just to clarify have tried to reset on power up and nothing also tried to get into engineer service screen and again nothing
There are have previously mentioned two other guys looking for the same answer on here
