Ok, tonight, while watch the TV, the TV suddenly turned itself off with rapid green flash (as before... I got the main board replaced last time due to same issue - under warranty).
After green flash went off, I was able to turn the TV back on and finish watching the TV.
Now, it is 7 mo. out of warranty period, BUT I bought the TV using my Amex, so I should have another 5 months before THAT warranty runs out I guess.
does anyone know REAL reason behind this issue?
I don't have any other issues, no issues with pictures/colors, etc.
After the mainboard replacement, I had no issues what so ever until today.
I wish I know the REAL issue, is it overheating? Should I install the additional USB fan that some people talked about?
