Re: tv tube problem
It`s total vertical collapse, which means 3 possibilities, vertical IC has failed, vertical IC solder connections are broken, the B+ line (voltage to make IC run) to the vertical IC has failed. None of these problems are big dollar repairs, 1/2 hour repair by any qualified tech, Good Luck & Happy Holidays, BMW Rider

I had a television that went to a bright shade of blue.A friends neighbor worked for sony television plant where the new tubes came down the assembly line.His job was to make sure tubes were working fine,if one color was dominant then his job was to smack the front center of the tube with a rubber mallot to fix the problem.He suggested i try that with my tube while the set was on.It worked and solved my blue problem.Apparently he explained,the gun connections in the tube came loose and to fix it was to smack it this caused the connection to reweld itself.For you I would use the palm of an open hand and smack the tube dead center with a good hard smack.Dont be afraid of breaking the glass because its very thick and strong.Give this a try.Hope it helps.Good luck!
If the horizontal lines going through the picture are fine white lines, then I would suspect the picture tube as having a heater to cathode short or some other problem. Since some sets have had a 3 year warranty on the picture tube, you may be lucky unless the labor to replace the tube is more than the set is worth. Sanyo is usually not a good name in consumer electronics anymore, so if you're looking for a replacement I would look elsewhere.
I think your problem is with the crt circuit. It is the one on the rear of your picture tube. Some loose connections may occured in there. Also, check if the flyback is arching. Sometimes, the voltage on the flybach itself causes this.
I have a curtis mathis console tv with a 8track player, casset player record player and a am/fm stereo, mod number on the box is F607 style TC2 seril number 04787814 new in the box never opened. where can i find out its value?
A "Gray Scale" adjustment may solve you problem.
If one of the picture tubes is set too high it will cause these RETRACE lines.
Then too a weak picture tube might cause this.
If the horizontal lines are one color: red, green,or blue then whichever color that is shown would tell you which tube is set too high.
Your set has 3 screen controls that control the brightness of each tube. One may need to be turned down a little.
dont know for sure but i think that the tube is going bad. Have one in my shop doing almost the same thing.Taped on the tube and it does strange things. My tube tester wont test this kind of tube that is in these sets.Not much help but it is a start.
