It looks like datasheets for the original are out there. Look at the datasheet and find a new bridge rated for the same or greater forward current and peak reverse voltage.

Also I assume this rectifier is opperating at 60Hz line voltage in circuit....If it is opperating at a significantly higher frequency look at the switching times of the old and new part and make sure the new part can switch atleast as fast.

the pinout may be different. Labeled plus and minus but on the same side not diagonal so I thought the whole part could be weird. Wish I could get original.

That's why you need to compare the datasheets of the original and candidate replacements. The pinouts should be on the datasheets, and you may have to do some special retrofit work to make the connections if you can't find a drop-in replacement.

Changed bridge. Pin configuration was different. Set now comes on with beautiful Pic. Now after a few minutes I get intermittent horizontal streaks in picture affects luminous not just one color. It will stop for a while then comes back. Look like it will be hard to locate Doesn't seem like any pots. I will run set for hours and see if it gets worse. If anyone is familiar with this Sony problem please help.
Thank you,

Are you using VHS or DVD/Blu-Ray as a source? If so it could be macrovision copy protection from the disc you're seeing.

It only does it for 30 seconds now when first turn on TV so I'll never find it. Think it will go away? How do you properly set screen background and drive controls.
