there is most likely a knob on the inside that will solve your problem.

Keep in mind that there is 20,000 volts or higher inside a CRT television set so if you trek to resolve your issues with it, be careful. ; )

Whoops, I forgot about the 20,000 - 30,000 volt part.
Prob won’t kill you, There’s very low current But it sure will shock you though!!
Don’t touch or come close to anything metal. Especially around the tube.
I always drill a hole in the back case of my tv’s and monitors so i can always revisit the focus knob easily.
I’m a freak about focus and it pisses me off that they hide that knob. I can only imagine how many tv’s are thrown out because of lack of access to a simple adjustment.
