The Flyback transformer is arcing. You could change it or if available replace the whole module. Let me know if this helps.

Loud popping noise tv


EHT arcing takes place. Never switch the TV on, until this fault has been rectified. Doing so, will make too many other faults to occur. Contact any service technician.

I get interferance mainly red and green lines appearing on top of the picture plus crackling noises


Please put off your tv and open the back side of the TV. Look for dirt on the back side of the CRT that is causing the arcing of the high voltage. So when the high voltage is sparking against the ground section the lines are coming to the screen. So use a good dry cloth to clean and wipe clean.Use a good solvent like methy spirit to clean. Check to trial and repeat if the fault is repeating. Make sure the HT lines are not touching but keep them apart to redduce the sparks. Hope this will get the TV right. Good day

Weird sound coming from the inside


Hi,
TV needs some kind of service and dust inside to be removed.
Regarding sparks sound, it can be leakage of high voltage of Fly-back Transformer. Qualified tv technician can check and repair it as high voltage risk is involved here.
Thank you.

RCA 20


sounds like the Power Transformer to me,  usually accompanied by a high pitch (almost inaudiable whine) and  sparks arcing.

 

This needs a professional repair..

Rca tv electrical problem


Hi, If the TV is still operational, what you are hearing are probably high voltage arcing. Most common are in the anode cap area brought about by accumulated dust, grime and dirt on the outer glass envelope of the picture tube. This occurs mostly after a continuous or heavy rain or when the surrounding air is damp. Since the unit is still operational except for the "sparks", this should only require cleaning of the above stated area. However, there are extremely high voltages even when the unit is off that perhaps you are better off seeking the services of a qualified TV technician. Other possible areas of arcing are the fly back transformer, the horizontal output transistor PCB soldering points, the G2, Focus solder points. in some remote cases, it can be just inside the neck of the PIX tube. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

Sparks


Where exactly are the sparks coming from? If you remove the back of the TV, can you see exactly where the sparks are coming from?

Tv makes whistling sound from rear and sparks when pluged in


By the sound of it your set might have a high voltage leak on the high voltage transformer ,the crt has a broken neck or shorted filaments,all 3 possibilities should be handle with care because of the high voltage involved,if you are familiar with tv service you can remove the back and take a look at the neck of the tube to see if it arks,remove the back cover from far away (12 feet)and then plug it in,if the tube is bad you will be able to see it but if the leak is in the transformer you might not see anything while is making the noise.If you are not too familiar be safe and call or take the set for an estimate.If the tube is bad you will need to buy a new tv.
