I have a DLP Projection TV Model #Z56DCD. I have purchased the new lamp for replacement and asked Zenith/LG Electronics for the procedure to replace this lamp. I was told I would have to have an "authorized Service Center technician" replace the Lamp because a "service remote" is required and only authorized service centers can get these "service remotes". Does anyone have information if this is correct? I have read and watched several videos on the Internet how to perform the lamp replacement (but not for my particular Zenith model). Any information will be appreciated.
