My TV is about 4 years old. Recently, I noticed it was making a loud, static-like popping noise, loud enough to distract you from the program. Now, when the pop happens, the screen goes blank. The picture comes back quickly. I've checked the cords and connections, switched outlets but the condition persists. Any suggestions?
HV transformer bad = please provide service number from back of set if you want the RCA part #.......T
I have the same issue with my RCA 32". I opened it and found that there is a component that has a piece of the rubber coating missing. I am now attempting to recoat the piece with some more rubber. I will let you know the results, but it is not carbon on mine. Mine is clean of carbon. I think this is your issue.
It seems that there is EHT Leakage from the EHT Transformer Anode Cap! Generally happens during rainy seasons, or if your TV is placed near a window or near an AC, due to excess of moisture in the air. Unplug the TV and wait for an hour to discharge all residual charge in Capacitors. Open the back, and look for a thick red cable leading from the FBT. (It is a Black Block with a thick red cable running from it to the rear of the Picture Tube). Take a sturdy Electrical cable with the conductor visible at both ends. (Multimeter Leads will do.) Now, ground one end of this lead to any Metal part of the Chassis, and gently ease the other end under the Cap of the EHT Cable. BE VERY CAREFUL, as there are very High Voltages involved! Do it Gently, and you will hear a POP! This indicates that the Electrical Charge inside tha Picture has been discharged. Now Take dry cloth and wipe clean the area around the Anode Cap. Close the back of the TV, and switch it ON. In all likelihood your problem should be resolved. BUT, I REPEAT, DO NOT DO THIS UNLESS YOU KNOW WHAT YOU ARE DOING, AND ARE VERY VERY CAREFUL. Otherwise, seek professional help!
SOURCE: popping noise
The anode cap on the back of the tv tube is leaking the high voltage be careful as going into the back of a tv it store very high voltage and could be fatal.the solution to problem get a tube of clear or red silicone discharge the high from the tube,you do this by getting a alligator clip with wire attach clip to a ground wire on the back of the tube attached the other end of the wire to screw driver gently push it under the Anode cap you will hear a popping sound with i little sparks. remove the cap from off the tube get some alcohol wipe the dirt away apply the silicone around the anode and the anode cap place in on back and leave it to dry and cure for about 7 hrs close up back and turn on your tv and all the popping sound is gone.good luck.but if it is the wire for the anode cap that comes from the flyback is the one leaking change the flyback.again good luck.contact me on fixya.com or email me at [email protected]

It needs a new FLY BACK transformer. That is what you are looking at. The origionals are not made for the set any longer but insist on having a generic on installed by a local TV shop. I just put one into a RCA 31" and it works nice. Don't throw away the TV. Get it fixed. MAKE SURE YOU INSIST THEY USE THE GENERIC ONE! THEY DO WORK!
