Question about RCA F32650 32" TV
you just start from speaker first. if the speaker is out there will be no sound output from your TV. To confirm this, just plug in an earphone or headphone pin into the headphone or earphone socket , if provided, on the TV. If sound is available through headphone, it means that the sound output section of your TV has no trouble, but the speker is out. Replacing it with same type and number will resolve your problem. If there is no sound fron the earphone too, surely the sound output section inside the circuit board of your TV has the fault.
If so you have to open your TV. Locate the sound output stage, which can be easly locted through following the speaker wires. There will be an Ic [Sound Output Ic], normally screwed onto a metal plate, to radiate heat out when it works. Check for any bad solderings at the legs of that Ic by tuning the printed circuit board upside down. It is very difficult to locate loose solderings. i always do is, resoldering the suspected solder points by applying a little more solder. You also do this first. If it does not help, resolder the Ic out from the circuit board, and go for a same type and number. Replacing it will solve your problem. In some RCA sets, sound section is built out on to another board. Locate it and do the same. OK.
