Question about Philips Magnavox 51MP392H Rear Projection Television

1 Answer

I own a 52" Philips DLP television and have sound but no picture

I bought a 52' Philips DLP over the summer and the guy that I bought it from said that all it needed was a new bulb. I purchased the bulb and installed it. When I turned the set on, the picture and sound both came on but after about a minute, I completely lost the picture. I don't have the manual so I don't know if this is something that I can fix or not. Can someone help me?

I would check to see if the lamp door is properly seated.These units will not operate without the lamp door in place or improperly seated.

PHILIPS 50 Inch HD DLP Projection TV the picture went out suddenly and there is not sound but a loud humming-buzzing coming from the set...any ideas on what could be wrong or if it can be fixed?


It's the optical block (color wheel) and the same thing happenned to our Philips 50" DLP. From what I've read, it's not worth the trouble & $$ to fix. Dig a hole!

Our philips dlp tv was getting a dark picture then today no picture but sound then the whole tv shut off and will not come back on do we need to replace the lamp?


Definately sounds like a bad lamp. A lot of times you can look down in the lamp and the filament will be broken or busted up. That would tell you for sure, but even if it is not visibly bad, I would definately try replacing the lamp first. I've changed many of them at our shop, and your description is definately a common symptom of a bad lamp in any dlp.

No picture


Pull the front cover off at the bottom. You will see a panel which has to be removed using a screw driver. Inside you will see the lamp assembly. It is a removable box. The lamp can be changed out by just changing out the connections on the new lamp. Before you pull it though try reducing your picture size to 4:3 it helped us to get a little more life out of our lamp.

Screen's color in black and white


your color went out because the color wheelor generators not working. These are sofisticated sets and if I were you I would call a pro as you dont want a local guy who knows little about DLP sets to cause the problem to 10 fold. Contact 800-211-PANA see if they can help
