Features of repair of TVs RCA, do not differ from repair of modern TVs of other trade marks. Faulty TVs can have a variety of character, because the TV device is complex, and its work is affected not only by changing the properties of any of the components (or chain of components), but also software violation - if the TVs of the first issues, equipped with processor control, programming was limited remembering the parameters of the image state, and also the preset channel and initial volume settings were stored in it. Soon the TVs disappeared organs of mechanical adjustment of the geometric dimensions of the image, the scope of color-difference signals - from that time the adjustments became available only to those who had the technique of entering the service mode of the TV, and the method of exit from it (which is also important). If you lose or destroyed the remote TV that was bundled with it (native), then the other, even despite the successful operation in the "user mode", often does not have the properties of access to the service mode of the TV. So try to keep your own remote.

Malfunctions of the TV components can manifest themselves in different ways. Periodic malfunctions with a monitored pattern of their manifestation, or that are not amenable to any logic, typical faults, according to which an experienced master can determine the model of the TV. It is important to pay attention to the "symptoms" that may have appeared recently, when the RCA TV of a particular model, was still before the aggravated state.

It is useful to verify the quality of the signal in one way or another, If the TV is defective, it is better to refrain from exerting excessive activity, dust, etc. The careless handling of the TV "stuffing" can aggravate the situation. Even if the antenna input of the tuner is broken off, or another port is damaged, it is better to not try to restore it yourself without having the skill.

The most important thing that should be paid attention in the first place is security. As a rule, in the instructions on the TV there is a section devoted to this topic. Read it yourself, tell your family.

For TVs older than two to three years, the on-delay is often due to a power failure. Further operation of the TV with such symptoms, as a rule, provokes secondary malfunctions, in the event of which repairs are often not cost-effective. Timely detection and elimination of malfunctions of TVs RCA promotes rational use of the resource put in it.
