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

Harry_22:
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?
