I have a 56 inch Panasonic DLP (PT56DLX75), that I have changed the lamp, but the display is still too dark. Did a factory reset, reset the lamp counter, cleaned and checked all wiring, still the display not bright enough. I can watch the TV sitting right in front of it in a very dark room. I am ordering a new lamp, but still wonder if the issue in the lamp or some where else.
Thanks for your help
