Do you think I can fix phone? (water damage)

I spilled tea on my Lenovo Vibe P1 and since then it does not charge. While it still had battery it remained perfectly functional, however battery ran out and I could not charge it again.

Do you think the problem is in the charging dock? I'm planning to buy a new charging dock from ebay and try to replace it. Do you guys think I'm locating the problem correctly?
