Picture bowing up in middle

While watching straight lines like the sat. guide the picture is bowed up in the middle. anout 3/8" at the bottom and 1/4" at the top. Is there an adjustment in the back for this and can I do it myself? I do have alot of video savy as I build computers and have fixed some TVs before.

Thanks

    Thank you. Since there is not a simple adjustment to fix the problem, checking caps and repairing such a problem is something I would not tackle by myself. But the info is important so when I call the repair shop I can describe the problem correctly. Pin Amp Distortion.

The most common cause for this are electrolytic capacitors in the pinn amp and scan amplifiers going out of spec with age and use. It is more rare, but it is still possible have other support components go defective in these areas. This fault is refered to as pin amp distortion.

I have repaired many of this type of problem over the years.

If you decide to troubleshoot this yourself, take care about the high voltages employed in the TV set.

This is probably the notorious "light engine" problem that all of these Sonys of this design run into sooner or later. It is usually more expensive to repair that what the TV is worth, sadly. A Sony authorized repair center can confirm this.

Convergence amps problem.

If it works after a kick I'd say poor solder joints on the convergence amp leads

Picture Distortion


you have a convergence problem.. If you understand how this works then you can go into the set find the convergence ic's and replace them and sometimes you need to do some alighnment as well. Its always best though to let a service tech do a job like this as he will have all the proper equipment to adjust and troubleshoot the set Good luck
