EN 6 2.
• For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:
• Always use the highest temperature to solder, when using
SAC305 (see also instructions below).
• De-solder thoroughly (clean solder joints to avoid the
mixing of two alloys).
Caution: For BGA-ICs, you must use the correct temperature-
profile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions).
You will find this and more technical information within the
"Magazine", chapter "Repair Downloads".
For additional questions please contact your local repair help
desk.
2.4.5 Practical Service Precautions
• 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.
• 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.
