Question about Prima CV1311 TV
My prima tv is sparking and making noise every time the power is on i took it aprt to see what it was and its at the bottom of the tv around a cord connected to a part the cord runs to the top of the tv connecting to something that looks like a suction cup what is this and how can i fix it?
The part with teh large red wire out of the top is as Azkeyz indicates the "flyback" transformer. This is the part that produces the high voltages required for the picture tube to function. As indicated, that wire conducts extremely high voltage that can injure anyone in contact with it. If there is sparking at the transformer end, then the part is beginning to fail. The sparking is due to a connection getting loose. The high voltage "jumps" the gap creating the sparking. This will only get worse. If the sparking is at the picture tube end, this can be fixed cheaply by carefully turning the rubber cap back and forth. Under that cap is a metal clip that can sometimes get a little dirt on it preventing good contact. That too will cause a spark.
PLEASE BE CAREFUL when attempting to work within the set. Even with the set unplugged, there is still a large amount of high voltage present. Think of the picture tube as a very large battery. THe high voltage remains for a very long time.

Warning: Flyback Transformer Failure. ( extreme high voltage ) 22,000 Volts +
Do not attempt to fix this without another human being present who's trained in CPR.
