Picture is too large for the screen, horizontally.
When you turn on the power picture comes right on. But, if there are words spread across the screen the ends of them will be missing on both sides. It looks as if the picture is too large for the screen. Even the faces appear to be wider. Aside from that the picture, the sound, etc. seems to be working fine. We tried to go through the remote functions to determine if something may have been out of adjustment. As far as we can tell everything is fine. We think that it has something to do with the horizontal. Is there a way to manually adjust this on this particular model?

Re: picture is too large for the screen, horizontally.
No my friend, there is a problem with the width circuit, and this would be in the pincussion correction circuit of the TV set. There is alot of high voltage in this circuit, and if you have no TV repair experience, play it safe and call in a tech to service this for you. there is not any adjust ment that will fix this. Good Luck

if its a cathode ray display its got vertical scan problems then its the line timebase more than likely a resistor gone high value or a leaky capacitor take the board out and have a good look for burnt out resistors and printed circuit damage change any electrolytic capacitors
I have the exact think happening on my Samsung LN46A530 and it has just been 2 years since I bought it. There better be a cheap fix for this because a $2,000 product has to last a lot longer than 2 years.
Are the lines all the way across the screen? or just a few? Solid black - or trannslucent?
Horizontal drive has either data, voltage, or control problem from the pixel registry circuit......get it serviced before the problem spreads causing further damage.
However, in all likelyhood, the panel itself is bad. The Bravia line has had a bad rap about the faulty displays, and at $1800 replacement (plus labor) - it may be time to call SONY direct to complain!
Sounds to me you have a cold solder joint ( loose solder connection ) on the printer circuit board around or on the vertical chip or on one of the vertical capacitors. You may also have a bad vertical chip or a bad vertical capacitor, but I doubt it since it did come and go. I'de get a soldering iron and some solder and touch up the connections. I will remind you that you need to always excersise saftey by making sure, before removing the back, unplug the TV from the wall, and use care not to come in contact with the large red wire going to the back of the picture tube as the picture tube can be turned off and still store lots of voltage ( up to 35,000 volts). Always stay safe and when soldering, use care not to run solder across places that will make a short.
Good Luck and I hope this helps

First of all, there is no such thing as a "high power flyback converter". There is a flyback transformer, but if it was bad you would have absolutely no picture at all. The fact that you dont even know what the basic components are suggests that you should not be "diving in" to someone else's TV. Do everyone a favor and allow an experienced tech to service the set.
