How much to repair a power board when TV flicker's?

Lg flicker's does any one know how much to repair the power board or replace it.

ANSWERS:

@deemarch08 are you sure it's the power board? I'd hate for you to spend $24 USD at great places like this or around $33USD at place like that. You can even pick those up on ebay for about $20USD.
