If the TV is broken - it is almost always possible to repair. Often breakdowns causes lie "on the surface", and the TV repair with the right approach is not particularly difficult. I still do not recommend poking around on their own, but the typical faults and repair methods will describe - just to let you know what awaits you in the repair and did not let the master cheat yourself. So, I present a list of the most common problems. If the "box" is not included, and even the indicator does not light, the source of the problem is mainly the power supply.
Often he will burn with voltage drops. The same reason causes spontaneous shutdown equipment. If the model provides protection against unstable voltage, at critical moments it will work and turn off equipment. We are confident that the differences were not? Then, the cause must be sought not only the power supply unit, but in the motherboard - it could appear microcracks.
Often there is a problem, which has two sources. The first and most common - remote fault. Suffice it fails to drop it or spill liquid on the keys, and it will cease to function. The reason may be more banal - just sat batteries you will not believe how many times this factor people took for the "damage".
Quite possible that the remote to do with it, and causing the problem becomes a failed control receiver. If everything is in order - to blame, most likely the processor.
You are trying to save a list of preset channels, but nothing comes out. The probable cause of the problem can be memory devices.
A similar problem: you save certain settings for example, sound , but after the restart saving technology disappear. In any case, the TV should be aimed at diagnostic memory chip study. If the violation is confirmed - it must be easy to replace. The TV does not respond when you press buttons on the control panel?
Rather, the point of contact is broken between the button and the control of its job microcontroller. So first of all you need to check the contacts, and if everything is in order - look for the cause in the failure of the microcontroller CPU.
