Thomson 50DSZ645 I have *as above* dlp tv. The picture has no brightness, and has been slowly fading over the last few months. it has got to the point now where it is in storage as the picture is just about viewable with a total dark room. Any suggestions? i have been told to get a new bulb? if so, do you know which one to buy? cheers

should have unplugged it when you noticed the smell.

UNPLUG and remove and look at lamp you installed--is something in the housing where lamp goes melted? I hope you did not touch the face of the bulb with your hand or fingers.

What ever is wrong find it before trying to use set again.

the problem is likely the projection lamp .. you can replace that yourself if you are handy .. you must unplug the set and make sure everything is cool ...avoid getting finger prints on the new lamp ...here are a few places where you can get a new lamp ... you can also see what it looks like on this site ...

the lamp is likely in a cubby in the back of the set (where you used to see the bright light) ...

the lamp is mounted in a cage ... you can get the lamp already mounted in a new cage from here ...

......it costs more mounted but its easier to change and you will need a new cage if yours is damaged .. from the site above you can see what the cage looks like with the lamp already mounted ..

your lamp is a model 915p049010 ... that is available thru amazon at a good price here:.(includes cage)........

You need a new lamp...

hats the shelf life on that tv

Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider

It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.
