Horzontal lines across top 2" of screen on both my Toshiba TVs?
This just occurred past 3 mos. - first one TV, then the other started with the horizontal lines. Newest was purchased 2004. Cablevision just left my house and Cablevision claims both my TV tubes are "going" - that I need two new TV's. If it was just one TV, I wouldn't question this - however, what are the odds both TV's (both Toshiba's) would have problems simultaneously. Has anyone heard of this? Hey, if they're on their way out, fine; but just curious if anyone else has had similar issues.
Thanks so much for your assistance!

It's NOT the "tubes" (the glass picture tube you view) this is 90% of the time a capacitor in the vertical circuitry. A good TV tech can find and fix this issue for probably a little less than $100 per set at the most.

Some components in the vertical deflection amp have been going out of spec with age.
The set may no longer be worth to spend money to service it because of its age. However, if you wanted to invest the money, the set is serviceable. Considering its age, the CRT may be soft, and there are many other older components that can soon fail.
well i think your husband is right. it might be three years old, but the sligtest damage can kill it. so what you need to do is start saving up for a new tv. sorry for waht happened. maybe somebody hit the screen?
1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect?
2.Or is thin Horizontal lines evenly spaced around an centimetre apart?
If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning.
If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.
