Casio calculator repair help required

In a clear example of abuse of power, NTRO employees have hacked multiple calculators of the google competitor and her family member to cause financial losses , waste of time during July 2018.

Due to hacking of laptops, the google competitor, whose identity was stolen by ntro employees was using calculators and keeping financial information offline.
The casio Mj calculator had been working properly for 4-5 years without any problem , however in June 2018, it suddenly stopped working without any valid reason due to ntro hacking. The solar panel appears to have stopped working.

Another calculator of a senior citizen has also been hacked to cause losses, a form of harassment . So it is better to purchase multiple calculators and keep them in stock, to avoid last minute harassment.

Any help to repair the casio calculator, MJ series will be appreciated
