Early this morning, my friend called me and said, "I accidentally broke my TV last night." He asked me to help fix it, and I agreed. At 9 AM, he brought the (CURIS) 32-inch LCD TV to my store. The model is LCD3235A, made in China. When I turned it on, it didn't light up at all, and there were visible signs of impact on the screen. Since we're good friends, I decided to take the TV for repair. I told him to come pick it up tomorrow, and he left. After that, I quickly removed the back cover and examined the internal structure. I tested the power board offline and found that the high-voltage power supply board was faulty. Also, the backlight tubes showed inconsistent lighting — three of them weren’t working. I realized I needed to replace the backlight tubes. The TV used EEFL lamps, which are driven by a high-voltage transformer in parallel. However, I didn’t have the necessary parts. So I came up with a plan: perform a full backlight conversion. I would replace the EEFL tubes with CCFL ones, which use multiple high-voltage transformers to drive each lamp individually. This meant I would need to install a new high-voltage board, effectively rebuilding the backlight system. To my luck, I had a spare screen from a disassembled unit. That covered all the required components, and everything was ready. But the process was quite complex. I documented every step with photos and shared them with my colleagues. Replacing the screen required both confidence and precision. Fortunately, I made no mistakes during the entire procedure. Thank you all for your support!
