May 28, 2021. 3. Restored Another Antique National RX-C37 Tape Recorder. This set belonged to a widow, who requested me to restore it so that she could play some old cassettes in which May 28, 2021. 4. No Power In Haier 32″ LED TV Fixed. This Haier 32 Inch LED TV came in for repair with the complaint of no power. DIGITAL CAPACITANCE LEAKAGE METER KIT Digital Capacitance Leakage Meter Kit. By Jestine Yong on October 3, 2010. This website was recommended by Ibrahim R from Kenya. Many meters out there do not have the capability to test leakage voltage but this one have seven standard test voltages from 10V to 100V, allowing most capacitors to be checked at or close to their ratedvoltage.
NO POWER IN RICE COOKER REPAIRED No Power In Rice Cooker RepairedThis Richsonic rice cooker came in for repair with the complaint of no power. Since the power cable and fuse were checked to be good, this means it was the internal fault and the rice cooker need to be opened for troubleshooting. It was pretty obvious where the problem was once the cover was removed. PANASONIC WATER HEATER REPAIR Panasonic Water Heater Repair By SK Wong From Malaysia. Removing the tar was very messy and tedious but If you do not remove it you will not be able to trouble-shoot.DRY SOLDER JOINT
Dry solder joint or dry joints cause lots of problems in electronics repair. It could cause an equipment to malfunction or give intermittent problem that is hard to solve. The dry joint can be easily detectable with our bare eyes or it could only be seend with the help of magnifying glass. SHORTED DIODES FOUND IN MAKITA BATTERY CHARGER An old man walked into my workshop carrying a battery charger that was totally dead and asked if I can repair it right away for it was urgently needed. I powered up the charger and sure enough there was no power indicator on the LED light on that Shorted Diodes Found In Makita Battery Charger TOASTER TRIPS HOUSE CIRCUIT BREAKER Toaster Trips House Circuit Breaker. Our toaster started to trip the 10 Amp circuit breaker when it was turned on. My wife, being a smart lady, thought it might be due to the fact that the microwave oven, toaster and jug were being used at the same time. She turned off the jug and microwave and tried the toaster. The circuit breaker trippedagain.
WHAT COULD CAUSE A TRANSFORMER TO BURN? 1) Lightning strike. 2) Power Supply Design fault. 3) Low quality of the transformer used. 4) Shorted components in corresponding circuit (primary side) 5) Shorted components in the secondary side. 6) Decayed glue used in surrounding circuit. If you know of any other way that could cause a transformer to burn please share your comment -thanks! HOW TO REPAIR SAMSUNG LCD TV WITH VERTICAL LINES The intensity of the vertical lines changes with the RGB signals and very prominent on white video signal as shown below: Since the vertical lines are not in the static location and always changing with the video display so, it is unlikely the LCD panel is at fault. The possible cause could be the main board, T-con board or both. LM317 ADJUSTABLE VOLTAGE REGULATOR TESTING METHOD I decide to make a simple tester and to show my method of testing this little but very handy component. The LM317 is a three pin voltage regulator, which comes in different package and different load current up to 1.5A. For a higher load, the regulator must be equipped with a passive or active heat sink to cool down the temperature of the IC.
