At the rear of the tv there may be two controls on the right hand side marked "screen" and "focus".If the set is newer,you will have to remove the cover and look to your right.You will see a dark object with a black or red wire coming out of it's top.That is your flyback transformer.On this you will find these two controls.Adjust your focus with the one so marked.Be careful to only adjust this control while you watch your picture clear.PROMPLY put the cover back.

if tv is too old tube might be going "soft" and sharp focus might not be able to be fully achieved anymore

good luck

Adjust focus


Focus adjust is located on the neck board or on the Flyback transformer, another fault is dirty spark gap inside the CRT socket

Digital Tuner


Most places listed "1 tuner" in specs. Was finally able to find a site where it listed the type of tuner which confirmed that it was not HD compatible. That was all I needed. Sorry I troubled you with this, I shouldn't even have been on your site with this Q. Thanks for responding. Potter1

Good day.
Try to check the crt socket. Also, check for the loose contacts along the Chroma IC. Like wise, there is a screen adjustment on the rear portion of the flyback. Try to adjust the screen.

Response is highly appreciated.
