Philips 27PS55 Vertical Problem
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 |

Philips 27PS55 Vertical Problem
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.
