SERVICE MENU CODE is the code to enter into the condition of “SERVICE MODE“. In terms repair television there are several ways, including using the code number or alphabet or a combination of both.I was using hardware tricks to the way right at the point to short/jumper / or provided in the switch (Sharp, SONY, Samsung, Polytron, Grundig, Panasonic, Thomson, Phillips, Pioneer, JVC, Toshiba, Tv China, LG, Sanyo, Hitachi etc).
Here I will give some way / code to open a menu of services from any brand of television.
