This forum does not advise on board level repair. There are no wiring prints available for the printers, so unless you get lucky and find the component causing the issue we can't help you.
That model isn't sold in the US, but if it were, it would be considered disposable. That means when it breaks, it's not economical with parts and labor to repair. Throw it in the rubbish bin and buy another one. I see they sell for 4800 rupees in India. That's about the equivalent sale price $79 US on similar models sold here. I know you don't make as much as we do here, but we couldn't do a board level repair here at a cost that would be worth it to the end user.
Good Luck
