This set will fire up, complete initial setup screen info, language, country, time zone. when select OK at end of setup goes to blank screen. Upon power up standby LED blinks three times. No response to remote. will not take software update through USB port. I noticed that with set off, all 13.2 volt pins show 12.0 volts. Once fired up shows 13.2 volts on same pins. Electrolytic caps close to the plug all show 12.0 volts in standby. LED Outputs are both 64.75 steady instead of 66 volts. Two main boards exhibit same behavior. A third main board would sometimes go into menu and even display PIP video and sound in menu on input selection screen. When input selected (HDMI) only audio came through, no display on full screen, this board took software update.
Could low voltage on SMPS be causing this behavior? I am stumped. PSON is 0 volts in standby, 1.84 volts when on. label on panel says Skyworth?
