You can find used power supply boards and main boards on ebay, maybe other sites that offer repair parts, but it's hard to say if the damage was limited to just the power board. You might get lucky and fix it with a replacement board, or you could end up several hundred dollars more to keep the TV working. You just have to decide if it's worth the investment to fix vs replace.
Since your TV was struck by lighting, the power supply is the first board that gets affected by the sudden change in AC power.. The main board is the next board due to the fragile components and the excess of voltage that is supplied to it when the lighting happened. Since you have replaced the power supply already.. I would suggest to replace the main board and that should restore the functionality on your TV.
Ensure the power outlet has power. Try TV on a different power outlet. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Best to take it to a repair centre as lightning damage can cause either minor fault such as an internal fuse blown or major problems that would make it uneconomical to repair. Ask for an estimate for the cost to repair.
