A Skyworth 32E15HR TV has three failures. Disassemble the machine and check that the insurance is in good condition and there is no obvious fault point in the main power supply. 5V standby power chip A6059 burst, chip ground current limiting resistor open circuit, the problem is not too big, after removing the bad parts, routine inspection of the surrounding originals, found that the switching transformer primary winding open circuit, which can be a bit troublesome, this machine is super Thin, and the addition of the overall power supply or AC transformer is limited by height. On the one hand, this 5V transformer has two sets of auxiliary windings and is at the hot end. It also needs to consider the thermal insulation and insulation problems. It seems that only the board is changed. Checked the price of the power board of this machine is not low, in order to minimize the maintenance cost in the case of ensuring the use of electricity, it is decided to wrap the transformer BCK-TD2204. After removing it, it is found that the skeleton is very small, and the winding machine can not be used. Wrapped up. After being wrapped, the paint is dried and dried, and the perfect output is 5.1V.
