These sets are common for bad connections on the ribbon cables connecting the screen to the drive printed circuit board. Or the drive circuit could have a bad drive scan IC. I doubt that but possible. Your going to need to call an AUTHORIZED sony repair servicer to trouble shoot this for you cause any other shop may not have a clue of this problem. Good Luck

This is caused by a failure of the optical block of your TV. The only way to fix the issue is to replace the whole optical block which is very expensive ($1000+) and time consuming (need to take whole TV apart to replace the part).

The optical block in your model had inherent issues and there is currently a class action lawsuit pending against Sony for this issue. Up to date information reguarding the lawsuit can be found here: http://www.sonya20tvclassaction.com/main/home.sfx

Hi. I am sorry to tell you that your LCD screen has finished its usefull lifetime. This is a typical pixel-line problem. This problem usually can not be fixed, It is necessary to replace the LCD panel. Though sometimes some lines disappear when you do some pressure round the egde where starts the line. To replace the LCD panel is usually as expensive as 80% of the Total price of the Device.

Hello,

Most probably the vertical deflection amplifier is failing. The most common part that fails is the vertical output transistor.
The set is too old to find documentation on part numbers and descriptions. Probably the part is no longer available and you will need the assistance of someone who can help you find an equivalent transistor that will do the job.
Of course, without testing we cannot be certain the failure is the output transistor. It could be from something else such as the voltage regulator that feeds the dc line to the vertical section. Could be the vertical synchronous level that goes too low to trigger the vertical sweep generator.

Other bad parts in vertical deflection circuit though there are not that many parts that would kill the deflection entirely.

Loss of power to vertical deflection circuits. Check for blown fusable resistors/fuses and bad connections.

Loss of vertical oscillator or vertical drive signals
Good luck.
