GRUNDIG LCD TV-schematic-Berlin, Vision-7 and Vision 9- How to enter the service mode, service mode adjustments method [Full circuit diagram]

 

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.

Because the material of the lens is synthetic and coated with a special anti-reflectivity layer, cleaning must be done with a non-aggressive cleaning fluid. It is advised to use “Cleaning Solvent.

Before touching the lens it is advised to clean the surface of the lens by blowing clean air over it.  This to avoid that little particles make scratches on the lens.

The actuator is a very precise mechanical component and may not be damaged in order to guarantee its full function.  Clean the lens gently (don’t press too hard) with a soft and clean cotton bud moistened with the special lens cleaner.
