In the morning, I worked on repairing a Haier power board. The response was really positive, and several of these units have already arrived for repair. In the afternoon, I’m going to pick up some dry goods. This is another Haier power board, and it seems more classic. However, it’s been damaged pretty badly and might not be worth fixing. As you can see, capacitors C35, C36, and C37 are burnt or cracked, showing signs of leakage. U1 (1377) is damaged, V2 W10NK80Z has failed, and FUSE1 (6.3A) is open. According to the schematic, C35 and C36 are 102/1KV, while C37 is 472/1KV. I replaced C35 and C36 with larger 681/3KV capacitors, and used a high-capacity reverse capacitor for C37 (4700P). This fix worked well without needing further replacements. These are peak absorption capacitors, so their voltage rating is definitely sufficient. V2 was replaced with K2968 from a plasma power board, and U1 was directly replaced. This made the board functional again.

Speaking of online shopping, I usually buy parts through a mix of local stores and online platforms. For washing machine accessories, I prefer local shops, but for electronic components, I go online. It's always a bit of a treasure hunt. Since 2008, I've been buying at V4 level. I even bought some for others and added 10W to the price. Everyone loves online shopping because it's cheap, convenient, and easy. My personal trick is to check the seller's feedback rate—preferably over 99%. A high rating means better quality and fewer issues, which saves me from return headaches. If something goes wrong, it's frustrating. But now things are better, and there's no reason to return within 7 days. That’s good for consumers.

I recently ordered a 681/3KV capacitor from two different sellers. The picture showed a large size, but the actual product was smaller. I didn’t ask for a refund and left a negative review instead. Just a heads-up for your reference.
