一台汤姆TM-900型全启动相机,一次使用完后倒片时,出现卷片到头马达不停转的故障。其他功能正常。 此故障在TM900和900D型机上最为常见。可用下法修复:先拧掉固定前后盖的八个小螺丝。这几颗螺丝都在外壳上。然后小心地拆掉前后盖。要注意的是要先拆前盖,再拆后盖,拆取时要用巧力,这时可看到整个机芯。紧接着再找到机芯电路板上体积最大的一只电容,可看到电容下面固定着的两片薄铜片,这两片铜片就是倒片
A Tom TM-900 full-start camera, a re-use after the end of the film, the winding motor appears to stop the problem. Other functions are normal. This problem is most common on TM900 and 900D machines. The following method can be used to repair: First unscrew the eight screws fixed before and after the cover. These screws are in the shell. Then carefully remove the front and back covers. It is necessary to pay attention to the demolition of the front cover, then remove the back cover, remove the use of clever, then you can see the entire movement. Then find the movement of the largest circuit board capacitance, you can see the capacitor below the fixed two thin copper, the two pieces of copper is rewind
