I am going to tell you a simple thing to do to know what your problem may be.
With the set on turn the color all the way to zero. Go to a channel if you can that is in black and white. What color is the screen?
If the answer is that it is blue in the background whoever serviced the set did not and could have removed front speaker grill and inspection plate behind it; there is a black plastic block with three screen controls (red,green,blue) and 3 focus controls (do not touch the focus ones.)
I suspect if the blue screen is there a slight adjustment of the blue screen down will correct this.
The picture with the color at zero should be black and white or gray. If blue is background color it will also be with color.
This is called gray scale; picture with color off has to be gray or black and white.

Check your closed-captioning setting and make sure captioning is turned off (or set for captions if you really want them). You'll find it's set to "text" mode right now. The set is blanking out a portion of the screen to display text it never receives, and you'll only see this when you view a channel where captions are being broadcast. Most sets have a button on the remote for captions, and it's easy to switch modes without knowing it. Then you wind up with the mysterious black box.

The answer is yes, you will be able to pick up and display HD channels. You will have to use your component video cables between your cable box and your TV. Component video will allow you to view low to medium end HD pictures.
the easiest way is to turn the color all the way down to zero. Then notice the overall color of the screen, if it doesnt appear as a good black and white picture you will have to adjust the screens. To do that you have to remove the speaker grill cover and the small access panel, then depending on the chassis you will see a small square with 6 dials on it 3 on top and 3 on the bottom it will have screen stamped on it. adjust those 3 untill your screen appears the best black and white picture as possible. Now if your chassis only has 3 dials on the sgaure control box those are focusdont adjust them. . then the 3 CRT boards will have the dials you need adjust those for the best black and white picture. when your satisfied that you have a good black and white picture. then turn your color back up and adjust the tint.Let me know if you need more assistance.
