During the Qingming Festival, the rain is pouring, the weather is humid, and 100% on the hygrometer is no longer anything, anyway, the walls are full of water. You're right, this is the famous south wind day in the south. A week passed, and the old man called me and said that a Toshiba LED 46-inch TV set in the house was hung, the same TV they were watching TV in the bedroom. According to my meaning, just buy a new one. The old man said, Toshiba TV is very good, no advertising............., 1000 words are omitted here.
Study it, press the boot button has no reaction, the power light is not on, and pressing the remote control is not OK. My years of experience have shown that there is a high probability that there is a problem with the power supply.
Opening and dismantling, it should be said that the industrial design of Toshiba TV is very good, anyway, it is to remove a bunch of screws, and the back cover is taken down. In this way, the interface and wiring are quite regular, thick metal support backplane, a thumbs up.
Normal operation, measure the 220v power input, normal, fuse, normal. Measure the output without electricity, sure enough, the power board is hung (state that I studied electrical majors in college, belongs to professionals, if you do not understand electrical, please do not repair yourself).
This thing a bunch of components, although I am an electrical professional, not can not be repaired, in the absence of drawings, I preliminarily estimated that it will take several days, may not be able to get it done.
Open a universal treasure, search, this power board is only 40 yuan, plus freight, 50 yuan. Casually find a closer order. Search skills, brand model power board, found the board generally has a number, take a photo and send it to the seller to confirm it. This thing remember to buy a freight insurance, if the bad luck in addition to the power board hanging, other also hung can also be returned
Arrived 2 days later, it looks like a disassembly part.
The rest of the things are simple, install the board, connect the good line, and boot up smoothly.
50 yuan, plus my knowledge in college, it is still worth repairing this TV set, the old man is very satisfied, I am also very satisfied
