Last night, a user brought a Sanyo 32-inch LED TV. The fault phenomenon is three no, the indicator light is not bright. I have seen that the screw has been disassembled, and the body has a phone number attached. It must be found by someone. Asked, he said that he was looking for someone to say that the main board was broken, and the change board was 550. He did not repair it. I took a look at the screw and the board was a three-in-one board. It didn't move. The power supply had no output. I told the fix that the red-brown color was fixed. The user agreed to repair it, left the phone, and told him to fix it and call him.
