The sound went out while watching a program on the set.
My D52W136D RCA was working fine and then the sound went out. I checked the sound settings and mute, all the settings are fine. I connected external speakers and got sound for one day then the next day the sound would not work. The picture is perfect.

It sounds like the IC that controls the sounds has gone. Once upon a time they used to start with the letters TDA and other sets of letters that would make them instantly recognizable but nowadays it could start with anything so unless you know what you are looking for call out a technician. Good luck.

Common issue in this model---look to see if the option for convergence still appears in the menu---if not you have a bad part right at the flyback causing this---a kit of 3 parts is available (tvparts.com).
Set is also for this issue prone to bad solder connections at the flyback and right around it that will cause convergence issues.
Yes, just make sure your converter box has composite and you're set to go. Your antenna will then plug directly into your converter box. If you end up needing more than one port (dvd player, gaming console, etc.), grab up an A/V switch which also works off of composite and you're all set to go.
It sounds like your color processor may have gone bad or at least the circuitry connected to it. To solve this problem you will need a schematic, a digital storage oscilloscope, a signal generator, and a multimeter. Now if you don't know what these devices are and do not have a background in electronics, I would suggest that you take the TV set to a qualified TV repair person. I am not trying to put you down or anything its just that this problem requires that you open up the set and using the schematic trace down the signals that control the LCD screen and find out the condition of the signals that display green. Since green is the result of the algebraic addition of red and blue, you may have a problem in the circuitry that controls that function.
Does the standby light flash in a set pattern? Some tv have a error code system which pinpoints the fault by flashing the standby light a certain number of times. Other than that my best guess would be a fault on the power supply or a fuse blown internally. Good luck.
Check your audio out configurations on your TV menu, this includes mute and volume control. After checking them, then try to see if any audio is coming out of the other audio outputs. If there is, then you may have damaged speakers. If there is no audio on any of the outputs you may have a damaged audio output processor or a poor connection in the audio section. If this is an audio circuitry issue; I would suggest that you take the unit to a TV repair shop for an estimate, and let them repair it.
