Howdy Do Senor Budm, I ran across a forum conversation you had with Ali101 regarding his Sony KDL-60W630B red light flashing 6 times. You were able to walk him through the testing and identified a faulty Zener Diode on the power board. I was just wondering what you opinion on the Sony troubleshooting chart is. For 6x blinking led, check JL9106 at (Backlight_Mon) of CN9101 of the Baxl Board...if it reads 1.3-1.8V the power board is the issue, if not its the Baxl board. I found where CN9101 is located, but do not know which point is JL9106. Just hoping you could point me in right direction.
