Samsung TXN2668WHF pincushion & sound issues (26" 16x9 HDTV)
I have the chance to pick up a Samsung TXN2668WHF 26" 16x9 HDTV at a very
low price. It was used as a store demo and has the following issues: There is no audio from the speakers. The picture is only filling about 80% of the screen horizontally, has a large amount of pincushion distortion, and Are either of these common issues? (Failed ampifier IC, bad caps in power supply?) Is there any place I might be able to download a manual, repair guide, or get technical information on this TV? Awol awol [AT] i-hacked [D0T] com |

May want to have an Samsung ASC check the unit out. Downloadable service
manuals are available to ASC from Samsung's Corporate Web Site. Check active devices in the PCC circuit and audio circuit. Possible that the supply to both has a fault. Look for open resistors to the affected circuits and ESR the caps in the same areas. "Awol [AT] i-hacked [D0T] com" wrote in message news:1bI_c.5067$OZ6.4230@okepread06...
