PT-50LD54 is an LCD rear projection TV with a consumable bulb that wears out normally after 2-5 years of use.
Most likely you need a bulb. That is first step in any troubleshooting for that tv. Check out Panasonic Gallery to identify lamp and replacement bulb.
Changing bulb involves removing the lamp assembly and replacing the bulb in the lamp assembly. Like doing a puzzle. Requires philips screwdriver, pliers and patience. Don't have jam on your fingers when you do it.
sometimes lamp is replaced in the front of tv.If so the panel under picture pulls out revealing lamp housing which is held in with a couple screws.replace lamp housing assembly
that is an overheating problem. With the TV unpluged clean and or vacuum the internal tubes. Not the lamp though. Do not touch the lamp as any oils on your hands will cause a hot spot and the expensive lamp will fail.
you can get the service manual at the following link for youe model DLP and they provide free tech support to help you diagnose your set. http://servicemanuals.vstore.ca/
to get rid of "replace lamp" push the blue action button on the remote and the volumn down on the tv set for a couple of seconds. this has to be done at the same time, good luck.
