I had made a previous video called free energy Vs the laws of physics, and I had talked about some of the devices people built, hoping they could build what amounts to a free energy motor. or better known as a perpetual motion machine. Shortly after I made the Continue reading The mysterious back spike is not free energy,
http://www.tvrepairinfo.com/ The television I repaired in this video is a Samsung UN32EH5300FXZA. I had mis-stated the model number in this video so please take note. This TV came in my shop dead. My first guess was bad LEDs since I see this so often, but it turned Continue reading Samsung TV Main board was bad. Here’s how I figured it out. Model # UN32EH5300FXZA.
This video was made some time ago. Playing with the charges that make lightning can be a high risk experiment, but since my long wire antenna has a ground and a spark gap, I think It’s probably safe enough.
http://www.tvrepairinfo.com/ This video describes how corrosion in slide switches used in consumer electronic equipment may produce a variety of symptoms, many of which might mislead you into thinking a component has gone bad.
I’ve been getting quite a few calls for TV antennas this last year, and one thing I’ve learned is getting an antenna up high isn’t necessarily helpful when you live in an area surrounded by lots of mountains. In this video I showed one such example.
I recently had Continue reading TV Antenna height doesn’t always help.
This VCR came in my shop making a gear grinding sound as soon as it was plugged in, and it would not load my tape. It turned out that the infrared emitter had died, and it made the tape loading carriage think I was trying to insert Continue reading VCR was grinding gears due to a bad infrared LED.
A couple years ago one of my viewers contacted me, and asked if I had any idea why the bridge rectifier in his power supply blew up while he was testing it. Unfortunately he had plugged the meter probes from his meter into the current measuring ports, and didn’t understand Continue reading Your Multimeter Can Blow Things Up.
The Drone in this video is the Hubsan X4 Desire, Model number H502E. This particular Drone has been brought in my shop with a burnt out motor on Three occasions. Considering how new it is, I figured the motor would have lasted much longer, but after witnessing the circumstances which Continue reading Drone motor failure from over current. What to avoid.
http://davestv.jestinemichellepow.click2sell.eu When ohms law was first explained to me, I was clueless about how it could actually be useful in real life. Even though the math was simple enough, somehow I failed to grasp how it could be useful in troubleshooting or designing circuits. Fortunately a situation Continue reading Troubleshooting bad circuits using ohms law.
This video is about what can happen if you install a repair kit, and fail to detect what caused the components to go bad in the first place.
