TCL 40-L14XH2-PWC1CG power supply issue

Hi,
I'm looking for a scheme of power supply for my TCL TV that recently broke down. The signature of the board is: 40-L14XH2-PWC1CG. I need a scheme to know what exact capacitors and resistors to buy to replace the ones that have short-circuited. Unfortunately when I asked the manufacturer they say they don't share these information and even if they did, they would typically replace the whole power module instead of reparing it.
Thanks in advance for reply
