Question about RCA 14F512T 14" TV
It started few days ago when the TV was working for some time, suddenly it started to make cracking noise which is very loud and I stoped useing ever since.
Model: Technika pro
HD Digital LCD TV/DVD
Nicam Stereo Sound
Its the plastic cassing making the noise. If you press the tv together along the edges you will here a crack. Samsung and others did not use 99 cent padding between the plastic and the metal you need cushion padding. Its like not using a gasket or seal. Its a simple fix but the tv companies say its expansion.

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@example.com
