How to check fuses, diodes, transistors, mosfet, voltage regulators in circuit and out of circuit boards, if TV doesn't turn on or has no red standby light then check the power supply fuses. Some fuses can blow out during a surge or lightning strike or shorted diode or transistor goes out.
Power Transmission Engineer Lionel Barthold Explains how 3 phase, 6 phase, and 12 phase power works, advantages, disavantages, and hopes for the future. Rotating phases, form an anisotropic tube. He worked on experimental 6 and 12 phase power lines at his company Power Technologies, Inc. before it was sold to Siemens after a long successful career. The experimental polyphase lines were located in Malta, New York, not far from company headquarters in Schenectady.
In this video, I have shown how to use an old SMPS of your PC as Battery Charger of 100 Ah, and smartphone charger. Step by step guidelines for each output voltage with amperes.. The output we are getting from old SMPS are- 3.3 V ...... 14 Amp 5 V ......... 25 Amp 12 V........ 14 Amp 5V .......... 2 Amp -5 V -12 V...

The fingers have an undeterminable amount of gold. This enables sellers to charge more than they are worth. This video shows that it's not easy to get the gold and how much there is to get. Now you have a place to look BEFORE you spend hard-earned money on the overpriced scrap.

The performance is quite good in comparison with other models which cost around the same.
