Sony Rear projection tv lost picture and there was a foul, burning smell

Shop around for the Big Screen repair Tech. Shop.The problems u discribing,the tv have more than a dead projection bulb.Circuits boards have burn components,must be trouble shoot and replace first.Before even know the static of the projection bulb.

Bulb may have popped. Cheapest fix, unless your an electrician it the only thing to really try before replacing set.

lamp cover door is melting maybe, double check it

This is very simple to repair if have burning parts smell,replaced parts that burning smell,the parts that cause by the burning smell part,make it to dies that hard to find.My sugestion replaced the DM power board,first to get power back,than go on from there.

Usually, yes. A bulb that has audibly 'popped' will be apparently bad if you pull it out of the TV (shattered). Other times this is a lamp ballast board.

Burning smell can be caused by a blown component, a short, or dust burning inside circuits.
In all cases do not turn TV on untill the TV had been tested and the problem is fixed as you risk to cause further damage to the unit.

Regards.

Thats funny!My TV is doing the same thing,but now I hjave no picture just sound!

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...
