Hi! Thanks! I haven't seen TP1 signal. Please use oscilloscope. Also measure voltage by DVM at TP1 and at pin 4 again. Every time check for "700" on the screen. |

OK, please watch the video |

Please connect oscilloscope to TP1 and don't disconnect it. Use digital voltmeter to measure voltage at pin 1 and 4. |

Could it be that the ceramic capacitors failed and caused the failure? Or is there leakage current? |
