Service access is intended for authorized service centers and service
providers only due to the ability to easily create malfunctions and render the
product useless. Digital displays are even more susceptible to this problem
where you could lose the picture altogether or prevent the display from
turning on requiring the product be returned to the factory to have the data
reinstalled. Access to this function could void your warranty. This forum is
