Question about RCA 20F420T 20" TV
Tips for a great answer:
Plug your headset to the earphone
jack (if installed) of the TV.
If you can hear the sound there, the fault may due to
speakers or the earphone jack itself. Faulty internal speaker
may replaced with new sets to back your sound to normal again. If
the earphone jack was faulty, you may spray it first with electrical contact cleanerwhile inserting and pulling the headset plug into it for one
minute to clean the contact. If nothing happens, this
jack need to replaced with new one.
If you can't hear the sound after inserting your headset, this is
an indication that the audio
circuitry was gone bad. The
most common caused of this trouble was the faulty sound IC(mounted in heatsink).
This is the one converts the audio signal to sound and feed to
your speaker's. I would advice you to look for a qualified technician to check
Hope I helped you.
Have a nice day!
