GIGABYTE GB-BKi3HA-7100の修理

I repaired a broken GB-BKi3HA-7100 that a friend gave me. The problem was that the power would shut off during startup. I hope this helps with your next junk repair. I used the following tools. *This list is general, so some tools may not be used in all videos. *Amazon links use Amazon Associates. (Affiliate links) If you're interested, try searching for the product name. ●Preheater 853A https://amzn.to/3JhbR8l It's a little cheaper on AliExpress. ●Heat Gun 858D https://amzn.to/3PRJlfn (No longer available) A cheaper successor (?) https://amzn.to/3zsR6mv ●Soldering Iron 1 Made in China (Used for cleaning BGA patterns, etc.) https://amzn.to/3RWR3GO It's cheap and has a temperature control, so it's easy to use, but it heats up slowly... (Probably because the heater is for 200V, so it doesn't produce enough power when used at 100V) ●Soldering Iron 2 HAKKO FX600 (Used for detailed work) https://amzn.to/3PAJOms Just buy this, lol ●Flux Liquid https://amzn.to/3ikgpBA Gel https://amzn.to/3OEpfV6 ●Solder wick goot CP-3015 https://amzn.to/3PyXD4K ● Seek Thermal Compact Thermal Camera For iPhone https://amzn.to/3z7fzMS For Android https://amzn.to/3jYa1R3 It has a decent resolution, making it easy to identify heat-generating components. ● Multi-Function Tester LCR-TC1 https://amzn.to/3dZkwR0 I use it to test components such as capacitors. ● 2.4-inch TFT Handheld Oscilloscope https://amzn.to/3pMQi6j I modified it to include a built-in lithium-ion battery (I'm currently using the OWON model below). ● OWON Handheld Digital Oscilloscope HDS272S https://amzn.to/3W37JhX This works well for most junk repairs. ● RIGOL DS1102Z-E Digital Oscilloscope https://amzn.to/3vLwALj I use this when the OWON model above is too difficult to measure. ● Tester INFURIDER YF-90EPC https://amzn.to/3cDsZbL I use this to display the tester image in videos. Normally, this isn't necessary. In fact, I don't recommend it because the mode switch often has poor contact. (I occasionally disassemble it and polish the contacts.) ● Stabilized Power Supply KKmoon NPS605W https://amzn.to/3cDaIvr (No longer available) I modified it so that the settings can be displayed on a PC via USB for video recording. I don't recommend it for repairing junk equipment because the voltage range is wide and it's difficult to fine-tune. (It's especially difficult to adjust around 1V...) ●PTC Heater -260℃ (Used for BGA Reballing) https://ja.aliexpress.com/item/100500... Although it's designed for 220V, it can also be used with 100V. (However, heating will be slower.) *You'll need to connect the 100V power cord yourself.
