五、创维彩电近期出现主要问题的解决方案 1.创维3528机芯(采用STV2246解码电路)主要问题解决方案 (1)创维21NF9000(3S28机芯)彩电,开机亮点。解决方案:请将C325电容容量由10μF/250 V更改为22μF/250 V。 (2)解码集成电路STV2246损坏多(3S28机芯)。解决方案:在C242和C243电容上各串联一个100Ω/0.25 W的电阻,要求串在电容的输入端。
Fifth, Skyworth TV recent major solutions to the problem 1. Skyworth 3528 movement (using STV2246 decoding circuit) the main problem solution (1) Skyworth 21NF9000 (3S28 movement) color TV, boot bright spot. Solution: Change the C325 capacitance from 10μF / 250 V to 22μF / 250V. (2) decoding integrated circuit STV2246 more damage (3S28 movement). Solution: A 100Ω / 0.25W resistor in series with each of the C242 and C243 capacitors requires a string at the input of the capacitor.
