- The on/off indicator blinks several times and then the TV does not work.
Let’s try to explain why this happens. And here 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 must be written to the permanent memory chip, and when you turn on the TV, the operating system will be read and loaded. Thus, the operating system is basically the same for all televisions, but the settings can differ dramatically. For example, you can set the screen type in the settings, if you change this setting, the TV may not work. If the settings are set incorrectly, the TV hangs on startup or restarts infinitely.
Restore your TV’s operating system, reset the memory in your Samsung TV
Restore the TV operating system, memory reset in your Samsung TV. Since when you change the settings in the service menu, the information is written in the permanent memory chip, if you set a critically incorrect parameter, which will cause a failure when you turn on the TV, you will lose access to the service menu. To restore operation of the TV, you must zero the information in the memory chip, this can only be done physically by shorting the appropriate pins of the chip responsible for clearing the memory. After this procedure, the information recorded in the chip will be erased.
After that, you must reinstall the operating system on the TV. Depending on the engineering decisions when designing the TV, a scheme may be used where the main operating system is recorded on one chip and all changes during operation are written to another chip, when the memory of the chip containing the secondary parameters is erased, the TV will resume operation by writing the new default parameters. And if all the information, including the operating system itself, is in one chip, you need to overwrite the chip memory with the correct version of the operating system. To do this is quite difficult, it requires appropriate skills and equipment, the chip must be unsoldered from the board. But, as a rule, it is easier to buy a new motherboard for the TV.
