Re: PG506 Repair - I had a Great Day today/
Just curious I measured in my PG506, B03xxxx.toggle quoted messageShow quoted text
+5V1 was 4.75 V, for convenience measured between pins 16 and 8 of U673.
+5V was 5.05 V, measured between pins 10 and 5 of U668.
About 0.3 V saturation voltage of Q70 is normal I think.
Even after 2 hours running with the display on the outside of T130 was not hotter than 50 degrees C, while the TM501 transformer is already almost 40 degrees C (measured with cheap IR thermometer). I don't know how much hotter the winding was.
