[Rozwiązano] Sharp LC-32CFG6022E firmware - Looking for firmware

Hello, I have this TV (mainboard TP.MS6486.PB710) stuck in service mode. I can't continue in service and I can't get out of service mode either. However, it searches for programs, finds them but does not save them, every time the TV is restarted, nothing is saved. Can we find a firmware for this model?
Thank you,

Look. Is for panel HV320FHB-N10

firmware may be not needed
enter in service mode with the sequence MENU 1147
then select shipping init or init tv and press ok to reset the tv

Thank you Yokoono51. Meanwhile, I found firmware for USB, loaded it, no difference. It went with billobirillo's method (Menu 1147, board init). Thank you both.
