彩色电视机在出现跑台、图像网纹大、扭曲等故障现象时,一般多为AFT或中频中周损坏所致。更换中周时一般都需要进行人为调整至图声俱佳。过去的老式彩电的中周调整较容易一些,而现代新式彩电的中周调整较麻烦一些。一般调整量较大的多为AFT中周,而中频中周只需稍作微调即可。我所说的“动中求静法”就是利用彩色电视机的全自动搜索功能,将AFT和中频中周调至最佳点。 Color TV in the emergence of treadmill, image textured, distorted and other symptoms, usually more than the AFT or IF caused by the week damage. Replacement of the week in general need to be artificially adjusted to tone sound. In the past, the adjustment of the mid-week of the old-fashioned color TV was easier, while the adjustment of the mid-week of the modern new color TV set was troublesome. The larger the general adjustment AFT week, and the intermediate frequency in the week just a little fine tuning can be. What I mean by “moving in pursuit of calm law” is the use of color TV automatic search function, the AFT and IF midweek adjusted to the best point.
