I have a 27"Apex TV,i think the model is 2702s.I have it for almost a year & around the 2nd month,I decided to install an earphone jack at the back and attached the TV's speakers to it.I'm not a technician,just like to tinker,& MOST TIMES,it works.Around the 5th month, I tried to rewire the speaker's attachment to the earphone jack(coz even if i adjust the balance to Left speaker,i still have a fairly audible sound from the Right one) then from then on,it has no sound now.The TV speaker's are OK(i tested it) but even when i try to put everything the way it was before,nothiing happens.Now,I use the RF audio out jacks at the back but I have no control over the volume whatsoever.Help!!I feel it just needs something minor like a buster reistor or whatever,I dont wanna be overcharged by a repair guy......Help??
