Hi folks. Giving this another try. Getting the two blink code - 15V SOS. Manual says to check the D board. I have. I get about 3.5V on pin #62 (I think this is the pin) of the panel Micro, which I believe is where this error is being detected before the set shuts down. I get
15.8V standby. I get 15.8V everywhere it should be at startup, yet the set keeps shutting down as soon as the voltages comes up. The service manual doesn't specify what voltage triggers the error on this pin. There are two high value resistors (looks like a voltage divider) across the pin that check good, so I believe the 3.5V is about what should be present. Other than assuming the D board may be gimped with faulty micro or something, anyone have a suggestion as next step? I'll set this one to the curb before investing in a board that may not be bad. Thanks again group.- posted
