So I got the service manual and been going through it lately of how to fix this overscan issues! Came across this, not sure what they're talking about, but maybe some of you guys do, here it is...
"1. connect an external video pattern generator to the aerial imput to the TV-set and umput a crosshatch test pattern. Set the generator amplitude to at least 1mV and set frequency to 61.25 MHz channal 3.
2. Set smart picture to NATURAL or MOVEIS
3. Activate the Service Manual menu
4. Choose Horizontal or Vertical alignments
Now the following alignments can be performed." (and it lists the actual HORIZONTAL and VERTICAL alignments).
So the question is what are they realy talking about before perfoming those alignments? Is that some sort of "generator" that can help you out to fix it, or it can be performed without what they said???
Any help guys???
