Yesterday morning, a customer handed me a note with a 200M resistor. The customer would come to me to buy one. I asked him if he was repairing himself or someone was repairing him. He said that the person who went to repair it asked to buy it. I am wondering, where does the TV need such a large resistance? I said, "Don't let that person toss, he can't fix it! I just sell it to you, it's useless."
In the afternoon, this customer and his son came over with a CRT big TV. I saw it, Changhong HDTV. Just ask him about the situation, "a line."
I opened the back cover, pulled out the circuit board, and observed it carefully. Except for the R406 resistance burnt, I didn't see the abnormality there. Horizontal line, only the field block burned out.
I checked the circuit diagram of this machine and saw that the R406 is a 12K resistor. Does that person ask for this resistor? Before you want to repair, tell the customer about the price: "red, blue and brown", the customer agrees. And he wants to come to the plane tomorrow and continue to repair other things.
This morning, it was raining heavily, and I started to repair this TV. According to the drawing, install the R406 12K resistor, the boot is still a line, and test the +B voltage 145V. I power off again, remove the STV9381, and only STV9388 at hand. Install directly, start the test, and pull the grating open. On the signal line, the picture is normal.
The drawings of this TV model are also presented.
