UNPLUG SET if you have not done so--fire hazard exists.

I would open rear and LOOK--see what if anything you can see that is burnt---all parts will have a location number printed under or next to them---will point to where problem is---make sure set not plugged in and do not stick your hands inside.

SOURCE: NO PICTURE, JUST A HIGH PITCH NOISE, SMELLS LIKE SOMETHING BURNING

Very common problem with these sets. The High Voltage transformer and the horizontal output transistor is most likly the problem.. If you know the saftey issues involved and know how to solder and unsolder, you can repair this set but theres a possibility you could also have a fault in the horizontal driver circuit, such as l401. if your not a tech its best to have this set fixed by a trained tech, if you wnt to spend between 175 to 225.00 Good Luck

Car is making a high pitch squeal some times when driving,noise gets worse when I take foot off the gas pedal. Also has odor of boiled eggs at times. Is this a tranny problem or emission system failure or...


The high pitch squeal ia most likely the serpentine belt on the front of the engine you can buy some belt dressing from the part store and put it on there and fix that or some soap will work also, the belt may also need to be tightened. As for the egg smell if it smells like eggs it's the catylitic converter doing it's job and is normal, although you should not be able to smell it inside the car when driving you may have an exhaust leak and could be very dangerous carbon monoxide exposure.

My 32v434t television.


The TV was making the clicking noise and not turning on because an internal error was being detected.
Now things had got worse , and something had blown inside the TV.
The burning smell and high pitched noise is coming either from Flyback transformer or PSU board. Repair is a delicate matter and must be done by a technician.

Sound like the alternator bearings are seized or about to seize. The noise could be the bearings or the belt and the smell may be either of them also.

Sylvania Television shut down suddenly with a high pitch sound at the back


TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
Figure on replacing the flyback transformer.
Hope ya fix it!
