SMD aluminum electrolytic capacitor

Telephone appointment to repair a 25-inch Hisense flat color TV, boot three no, the light is not bright, no degaussing start, after the insurance has been black, 9656 has been broken, B rectifier has been short-circuited, according to past experience, 9656 is bad The color line is caused by leakage, so it is necessary to change it with the user. It needs to be brown and red. The user agrees to choose the second time to change the color line and other accessories. I didn’t expect the CPU to be broken. I have to tell the user to change the board together. The change board should be red and yellow, and it can be guaranteed for one year. I didn't expect the user to be very refreshed. I immediately said that I would change the new board, so I chose to go out after the third time.
I thought it should be fine. I didn't want to call the customer that night and said it took more than two hours. The fourth time I went to check the damper tube, because it is a new board, so the new board test machine is normal, and the cover is on! The user called the phone again the next day. The fifth time I went to the door and went home to repair.
Check the damper tube again, thinking that the power is small. After using BY459 for more than ten hours, there is no problem. After putting the cover for more than ten hours, it is no problem. I didn’t expect to go to the user’s home for half an hour and burned again. I plan to give a refund, and people don’t want to, and I believe that I can fix it because people don’t want to watch LCD TV.
After returning home, I have not considered the quality of the board. The most skeptical is the deflection. I found an old flat machine directly. After the replacement, I flipped the cover and tried it for more than a week before sending it to the user!
This maintenance is over, it lasted nearly a month, now it has been half a year, and returning to normal when passing by!
