My RCA TV, D52W17, has less than 100 hrs on it. When I turned it on yesterday it made a popping and cracking noise from the rt side speaker. I unplugged the rt speaker and the noise quit. I swapped the speakers and the noise stayed on the rt side. Any thoughts? Thank You!

if no any power indicator the first place to be check is the power supply where in the fuse get blow. if the fuse blown with darkened color that was mean has shortened line, might the amplifier circuit get damaged that cause of popping before it totally down.check for bad amplifier ic and shorted diodes.
I had the same problem on my hd52w59 hdtv and sucessfully fixed it yesterday from an answer i found here...so hopefully im paying it forward.
First off, im no TV tech so you do this at your own risk!!! Based on the research ive done regarding this subject, if there is no issue with the picture and its not related to speakers(ie. if you mute it and it still makes the sound) then its the horizontal drive coil. The fix i read was to put nail polish or hot glue around the coil. Well i came up with something easier and its worked for a few days now(fingers crossed). An old fashioned wooden clothes pin. Put it on the horizontal drive coil and it absorbs the harmonic frequency(high pitch noise). I realize this is a wooden object on a electrical piece that heats up but i have had no issue as of yet.
Now, how to locate the noisy horizontal drive coil...unplug TV from power, remove the lower rear panel around where the wires go into the tv. There are about 8 #20 torx bit screws you remove, then use a flathead screwdriver to pop one clip on each side and 3 underneath, this will allow the plastic trim panel to pop off. Get a flashlight aimed in there so you can see the components. Plug the TV back in and turn it on...wait for the noise. Now make sure you dont touch anything high voltage and once again you do this at your own risk...but take a small wooden stick (i used the stick from a plunger) and touch it to the suspected culprit...when you touch the noisy drive coil the noise will immediately go away. Once you know which one it is turn the TV off, unplug it, and put a wooden clothes pin on it. Plug the TV back up, turn it on and ensure the sound doesnt come back before putting everything back together.
Beats the hell outta paying a technician $75-100 plus parts, huh?
for using FixYa. 3 blinks in your RCA D52W17 rear
projectionare caused due
to 3 capacitors (CP114, 120 and 150) which are located on the deflection board.
If any of these capacitors goes bad you’ll have to replace them with the exact
do rate the solution if the issue is resolved or post a comment for further
assistance. Thanks Rylee
Does it make a slight popping or cracking sound ? If so remove the back cover and see if the flyback transformer shows any sign of burning or arcing. It is located on the far rt. hand rear side with a red wire comming out of the top and a black one behind and lower than the red one.
Possiblility include bad convergence cuircit. A component that is overheating and bad solder connections.. Technicians can use special equipment to read error codes... this will tell them the error that is shutting it down
well u have a problem in the audio circuits of the tv which includes the speaker itself. but most of the time the audio power output transistor or ic get easily damaged resulting a no sound tv. if u dont have any idea with regards to this, i suggest have it check with a qualified service technician. it will not cost u a lot for sure.
