Bob, Try this: --------------------------------------------------------------- Text pasted from WinSTIPS 2.0 http://www.ServiceSoftware.com --------------------------------------------------------------- SONY KV27HSR10 Audio Inop. Dolby Module Nla. Workaround (Remove Dolby Module): From Apr. 03 Speaker / Page 3 / http://www.nesda-ohio.com/ Sony SBX1593-01 Bypass From Apr. 03 Speaker Page 3 OK, Maybe "Silence" is too harsh... It could be "Garbled", or "Noisy", or "Distorted", or "Static", but what is ISN'T is "NORMAL". We've encountered these symptoms before in other Sony's that use the Infamous SBX1637 Sound package. We've even come to love those SBX's as they have allowed us to put our kids through college from the income they generate. Unfortunately, there's Another SBX sound package that might cause similar symptoms, and IT has been decreed as NLA by Sony. It's the SBX 1593-01 (Sony # 8-741-159-30). Wouldn't you just HATE to have to trash a nice Sony TV because you can't get a part to fix a Sound Problem? Well, one of our readers has come forth to tell you of a way to bypass this circuit. To bypass the module: Use two 4.7@50 capacitors and connect the (-) side of one cap to pin 5 on the MTS module and the (+) side to pin 4 on the DBX module. Take the second cap and connect the (-) side to pin 6 on the MTS and the (+) side to pin 5 on the DBX module. This should give you clean sound but you may not have the fullness that the board would have given you." Well, a "Lack of Fullness" is certainly better than a "Lack of Sound" which is what the customer had before the bypass. Sometimes you just have to be creative to get a Fix. We thank our readers for allowing us a chance to get This One.
