This is what happened to me and frequently happens. I beleive this happens when the tv becomes too hot. What I did is diconnected the plug from the wall and it helped. I think that it needs to reset it self to be able to detect the new bulb. See if this works...

Never really had that issue the one I worked on Operated normally for 20 minutes and then shut down completely. The fix for that is to get the OEM bulb instead of the replacement

I have a mits. 82738 tv which would shut off after 20 minutes when first turned on .
Loose sound and picture.
Looked up error code in service manual and it said the lap was the problem.
Replaced lamp and now it works fine and the picture quality is great.

That sounds like one of 2 things:
  1. Color wheel
  2. Light engine
Color wheel because of the losing color, but the light engine because of the picture freeze. It's very difficult to judge since I can't be there to see it. I'm leaning toward the light engine though. The only fix is to replace the DMD board, or entire light engine.

Tv comes on for a minute and then I get the bulb failure light. If I unplug it and power it back on I get the same result, so it is not the bulb because it still works. What is causing this?


The would be the balast that holds the bulb that has give way, this would need to be replaced as its setting of a signal to shut your tv down.


I hope this helps

Your bulb is burned out. I have had the same problem. It seems this television has an overheating problem--and short bulb life. I have had our 50 Magnavox dlp for two years and just put in the second bulb before Christmas. You can buy the bulb from a dealer on ebay for $99 and install it yourself. I is not in the housing so you have to carefully take out 4 screws and replace the bulb without touching the face of the bulb. To buy the one from Magnavox with the housing is much more expensive. I think the first time my husband replaced the bulb it took about 45 minutes--this time it took about 20.

Akai PT50DL24 50 in DLP Rear Projection TV-NO PIC OR SOUND


check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.
