GRUNDIG VISION 7 AND VISION 9 BERLIN LCD TV SCHEMATIC DIAGRAM - HOW TO ENTER THE SERVICE MODE, SERVICE MODE ADJUSTMENTS

 Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

It makes sense to avoid exposure to electrical shock.  While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.
