Well it could still be a problem with the pins of the cartridge in general yeah. So don't have too high hopes. =/
But disabling the lockout chip is generally a good thing anyway. Since you say that you sometimes see a hint of text I think the game works but the connection to the lockout chip is spotty and therefore your console won't allow it to fully boot. But since the pins for the lockout chip seem to have a bad connection, other more important pins for the game could also have bad connections which might make the game crash and freeze etc.
If you run a q-tip with alcohol on the pins and apply as much pressure as you can, do the q-tips become dirty still? If so then do that until they don't become dirty anymore.
Disabling the lockout chip will also allow you to play US carts as well as Famicom carts with an adapter on the console.
Edit: Oh eh, beaten I guess hah!
