Pick one or more of the main causes for this,

1. the vertical output or its supplies
2. jungle/micro
3. eprom

Any of these three can cause the problem you describe.

Oops, forgot to add the yoke to the list although not near as common for
failure.

Good Luck,
Bill Jr

BTW, if you end up having to replace the jungle/micro, don't forget to order
the service remote as the new firmware just might have changed and normal
methods might not work anymore.

I have a Philips in for repair 27PS55 model 27T800 Chassis. I have no
manual
for this yet because it is fairly new. The picture is there but you get
black
bars in the middle of the screen. The bottom has a margin. The IC is a
TDA8359
for an output. Thanks
