Hi,
In shop is a Zenith TV A25A11D 9-1790-1 with bad tuner 175-2721. The clock or data line (don't remember which) was pulled low. With the tuner removed, the level is normal on both lines. I ordered a new tuner from LG-Zenith. I installed the tuner, powered up the TV. This time, snow and rush sound occurred (didn't before). I ran auto program, but no channels were found. Note: I confirmed good signals were present at cable. An article in E S&T 10/00 by Bob Rose states, "when you install one of them (tuner), you must make certain modifications to the control circuit, or the new L.G. Electronics tuner won't work. Note: There were no instructions with tuner. I called LG-Zenith and told the person about it, but she said she doesn't know anything. Thanks in advance, Brad Tip for your old computer (reduce discard pollution too): If you can't sell your old computer, don't throw it away. Use it to backup your software by transferring files/folders from your new computer or laptop to it. I transferred my Windows folder and other stuff to my old computer using "PC Link", which I downloaded from www.simtel.net (cool site). http://www.simtel.net/pub/dl/52792.shtml (info or download) |
