The question is straight. Does my TV 32LB3820 runs webOS? Do I have any ipgrade available? Where and how to upgrade?

You sure you have that model number posted correctly? I can't even find a Google hit for that particular number.

If you own an LG television model that does not have webOS built into it, there is no way of 'upgrading' to webOS. Your only option would be to purchase a newer model.
