Picture blacks out with audio remaining in any channel. Picture may attempt to return after minutes or hours. Sometimes screen has horizontal flashing lines or a faded picture and will then turn to full color with quality resolution for a short time. It then returns to a black screen. Screen remains black when changing to other Input components. TV menu can't be seen. Contact was made with "Dish" thinking the problem was with the satellite receiver. According to Dish, receiver is okay after going through trouble shooting screening. Unplugged both TV and Dish Receiver, and picture returned minutes later on its own. Receiver completed all downloading of update information. Picture was fine for 6 to 8 hours of operation. Original problem has repeated itself with screen currently black with audio. Can you say for certain the problem is with the TV and not the receiver? We live in rural NW Montana...are you aware of any TV Service or Repair businesses that would run the set through trouble screening for repairs?

Oh good, two people. I was getting weary of attempting to slightly change my answer for all the other people who didn't use the "has the same problem" feature. Anyway, the problem both of you have is not too far gone yet, but will get worse if you let it. It's the main capacitors. Maybe not all 21, but probably at least half of the 21 main caps are shot. All should be replaced at any rate. Any shop worth it's salt ought to be able to do this for you for under $400 if you can't do this yourself.

If you are willing, remove the speaker grill and the rectangular board behind that and look very, very carefully underneath each of the three picture tubes for evidence of coolant drops on the printed circuit boards. These sets have been known to spill a few drops of coolant onto the boards and this causes intermittent problems such as yours. This is my first direction in your case. Let me know.

Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
