There's a small village here, though the population is not large, it's very wealthy. That’s why the villagers have a wide range of entertainment options. There's a big rear-projection TV from Changhong in the elderly activity center. Back then, it cost more than 10,000 yuan to buy for the senior university. Now, I've been called in to fix it, but none of the three repairmen could do it. I had to go to class the next day. It was already past one o'clock in the afternoon when I arrived. After checking, it looked like it was getting worse. I just did a quick fix, waiting for it to be taken away. It was already after three in the afternoon. If we followed the usual process, replacing parts would be complicated, especially with the high-voltage capacitor, which is known to require removing many components. Seeing someone assemble a ballpoint pen, I got an idea—cut the three high-voltage wires and connect them back using the pen’s body as insulation. Before connecting each wire, I first put the plastic sleeve of the pen over the joint, glued it with a plastic rod, wrapped several layers of high-voltage tape around it, and then added another plastic sleeve. After this treatment, I turned on the TV, and the picture and sound worked fine. I didn’t hear any crackling or high-voltage sparks, which meant there were no major issues. This method saved time and avoided making the elderly wait until tomorrow at the senior university. Although it was just a temporary fix, it worked well enough. The machine is now fixed, but I still don't recommend this approach for long-term use.
