Posted question earlier. Answer was that I have a Vertical Collapse problem and internal components need to be changed.
What would the component be, and could a person that knows somethings about electronics change out the component themself?

civilman, the first set has either no high voltage or is collapsed vertically, until someone checks for high voltage there is no concrete answer, the AV27730 is vertical collapse from your description, either the voltage to the vertical IC is missing or the vertical IC has failed, not a big deal cost-wise, hope this answers your questions, if not e-mail me back, good luck, BMW Rider
deight, your set is going into total vertical collapse, either the vertical IC is failing or some support component to the vertical circuit is failing, should not be an expensive repair, hope this helps, BMW Rider
have a Mitsubishi TV 1993. Model CS-35301. The problem is that there is a white line that is running through a blank screen. The sound is fine just no picture. Have you heard of "Vertical Collapse?"
I would love to save the TV.
nothing to worry just minimise brightness to avoid screen burn.
means one bright hor.line in the middle of screen.
this problem can be solved
1 check vertical yoke connector or wire loose
2 check supply to vertical section which normally comes from EHT transformer
check components in vertical section or print loose
This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.
