I changed the settings in the TV service menu, the TV does not turn on how to fix it.
Quite a common situation, a service menu for professionals who understand what they are doing. If you choose the wrong settings, it may well happen that the TV has stopped turning on. If you have a situation that occurs when you change the settings of the TV;
- when you turn it on, the TV is constantly overloaded.
- the Samsung logo appears, and then a black screen.
- the on/off LED blinks a few times and then the TV doesn’t work.
Why this is happening, let’s try to explain. And we can do almost nothing on our own, because the problem is at the operating system level. The right solution is to restore the operating system in the service center.
TV, this is a smartphone with a certain modification of the operating system. The operating system has to be written into the memory of the chip of permanent memory and when you turn on the TV the operating system will be read and loaded.
So, the operating system is almost the same for all TVs, but the settings may differ dramatically. For example, in the settings you can set the screen type, when you change this setting the TV may not work. If the settings are set incorrectly, the TV hangs during loading or an endless restart.
Restore your TV’s operating system, reset the memory in your Samsung TV
Because when you change the settings in the service menu, the information is written to the permanent memory chip, when you set a critically incorrect parameter that causes a malfunction when you turn on the TV, you will lose access to the service menu. To restore the operability of the TV set it is necessary to zero the information in the memory chip, it can be done only physically by shortening the corresponding conclusions of the chip responsible for memory cleaning. After this procedure the information recorded in the chip will be erased.
After that you need to reinstall the operating system on the TV. Depending on the engineering solutions when designing the TV set, the layout can be applied when the main operating system is written on one chip, and all changes in the process of operation are written to another chip, when erasing the memory of the chip containing secondary parameters, the TV set will resume work by writing down new default parameters. And if all the information including the operating system itself is in one chip, then it is necessary to write down the necessary version of the operating system again in the chip memory. It is quite difficult to do this requires appropriate skills and equipment.
