The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.

How to fix a Zenith Projection TV. Could it be the bulb needs replaced? Is this something I can do myself?


The whole service manual is here: http://www.manualslib.com/manual/790821/Zenith-R50w46.html
But this is something that you might want to reconsider. The availability of parts could be an issue. The smell could be the ballast or the bulb got really hot and went out. The repair process involves troubleshooting with special meters etc. You may be able to spot something that burned out though.

I have a 1994 zenith big screen the picture is showing really dar


It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.

"pop sound", picture out, burning smell...?


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.

Wont turn on smell burning


Can you remove the rear panel and check if the hissing is coming from the flyback? Which is a large transformer with a large red wire coming from the top of it? If so can post a link where you can get a replacement their not exspensive and their easy to replace. If its not coming from the flyback post a picture of where the hissing is coming from and I will identify the parts for you, But I feel its the flyback due to the hissing. respond to this same post so I have your correct model number when you reply.

check around the flyback for burn holes or splits in its case. May also want to check the horizontal output and regulator transistors for being shorted.
