Zenith SR2568S Help Needed!
Hello Group:
Subject: Zenith SR2568S 27" TV This set had two (2) initial problems ... not sure if they are related: 1. Loss of Green Color ... I was able to repair this problem by resoldering some cold solder joints on CRT board. 2. If I turn the set to a channel above 39 (CH 42 for example), I can see the channel and everything "seems" ok however, if I turn the power OFF - Then back ON, the same channel will be selected however, all I see is "snow" (blank raster). If I flip down to a lower channel (CH 3 for example), then go back to CH 42, it works (can see the broadcast) I noticed that when I set up the Channels (via auto channel routine from the menu) the channels that cause trouble (e.g., CH 42) are not "found" during the auto channel search. I would really appreciate any repair info that you folks can offer!! Regards, RJ |

Check to see if the voltages to the tuner are correct. It is possible that
the tuner module is defective, and would require replacement. -- Greetings, Jerry Greenberg GLG Technologies GLG ========================================= WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm ========================================= "NPNTEK" wrote in message ...
