Red convergence does nothing

[Tricia]

I have a Apex GB5108 and the red doesn't line up. The blue lines up fine but the red does nothing. Can anyone help me? Is it something easy that I maybe able to repair myself.

Don't know the brand or type of the TV, but if it has a electronic convergence adjustment, you might check the horizontal driver IC's / circuits!

Had a few (other brands), in wich the driver IC (and safety resistors) were blown.
