Hey, whomever is reading this... thanks. I have a 32" Zenith TV that's not working . When I press power, it makes that short buzz noise that TVs make right before they click and the screen lights up, BUT it doesn't click and light up. If I keep pressing power, it will keep making that noise like it wants to start but then nothing. I have taken the back off of the set and checked the fuse (only found one) which is ok. Anyways, I have no idea what's wrong. If anyone has any ideas I'd appreciate them. Thanks!
...Ok, now I really think I messed it up!!! After putting the back back on and trying it again, it made a loud POP and now it smells really bad... Is there any way to save this???

Good Morning, zoomiezoomie:
Twas a sad day in Mudville, I'm afraid. The Mighty Sony has struck out.
The first situation that you described was the set trying to turn on only to run into a short circuit or circuit overload. At that point, the circuit breaker kicked in and prevented the set from achieving full operation. Of course, repeated tries rendered the same condition.
Of course, now you are smelling the results of the repeated tries. The short circuit or circuit overload has now generated enough current through the system to cause component burn out.
Without actually seeing the condition, I am having cause to speculate that the problem is in the High Voltage circuit. This is the circuit that builds a voltage of approximately 40,000 volts to light the screen on the picture tube. The smell may well be the quadrupler, a device in the final stage of the high voltage circuit.
At this point, it is time to have the set repaired. Unfortunately, this is not a failure that is easily repaired by the home mechanic and would strongly suggest you take it to a Sony Service Center. Coupled with the costs of the fork lift to carry this monster, the repair costs can be quite high. I strongly suggest you get some estimates before authorizing repairs. Repair costs vary from one shop to another.
