因彩色显像管的故障率占彩电的比例较小,因此一旦彩电出现故障,往往不会先怀疑它。为了使大家少走其弯路,现就彩管常见的故障与处理方法作一简介,以飨读者。 1.色纯度不良。在消磁电路及其它电路正常情况下,该故障多为受外界磁性物体的影响所致,例如磁铁、扬声器、电机、变压器的影响等。故障现象表现为电视机图像局部有色块,将色饱和关掉也无法消除。处理方法是用消磁器进行消磁处理,自制的消磁线圈也可以。
Due to the failure rate of color CRT TV accounted for a small proportion, so once the color TV fails, often do not doubt it first. In order to make everyone less detours, now the CPT common faults and treatment methods for an introduction to readers. 1. Poor color purity. In the degaussing circuit and other circuits under normal circumstances, the fault mostly due to the impact of external magnetic objects, such as magnets, speakers, motors, transformers and so on. Symptoms of the failure of the television image of the local color block, turn off the color saturation can not be eliminated. Decontamination method is to use degaussing degaussing, self-degaussing coil can be.
