Replaced bulb but still getting "lamp will fail soon replace" warning


When you replace the lamp, you need to reset the lamp counter as well. The procedure for this should be in the owner's manual. This counter is a guide only. Lamps have an expected lifetime and the message indicates that the lamp is nearing that lifetime. Once reset, the counter will again trigger the message once this new lamp reaches that usage time.

I changed the bulb in the m50wh72s RCA DLP tv. Before I changed the bulb I had sound. Now I have no sound or picture. Any ideas? Thanks


Check that when you turn on the TV the Lamp is striking (turning on).

My thoughts are that you will have to reset the lamp hours counter to make it work, as the TV does not know that you have replaced the lamp. To do this, check the leaflet that comes with the lamp - it should explain how to reset the counter for the lamp hours.

LP 530 Lamp does not power on


Did you cancell the bulb fault status in the main menu ie bulb hours when you changed your bulbs if not try this turn unit on and see if it works it may do.

To reset the lamp hours counter press and hold down the Volume minus button - , then press the source button whilst still holding down the volume button for 5 seconds .

If this works you can then verify that the lamp counter was reset by viewing the counter in the status window in the OSM

hope this helps... Regards Vortash
