Kenwood TM-732A Display Problem
I noticed tonight that my Kenwood TM-732A has suddenly developed some
garbage in the display over about 25% of it. Looks like fern leaves or something like that. The normal display items are still there. The garbage is in the background, but makes the display very hard to read. Am I looking at a new display? The radio does run 24/7 monitoring our ARES repeater. Maybe it just finally did it in.

If that is the case, then it is indeed new-display time. -- Mike Andrews Tired old sysadmin |

I was hoping maybe it was a display driver that was going, but I agree it looks more like the LCD itself. I never heard of the leaking problem. That's something new to me. I wish it were new to me, but it isn't. The Boy had his Palm i705 PDA in his pocket, unprotected, when he sat down, and pushed something else in the pocket up against the screen hard enough to crack it. As a result, air is getting into the liquid crystal layer. Initially, it showed as a fern-leaf-like change in the display; it has become _much_ worse over time, and now I get to order a new display and install it. In the case of your TM-732A, it sounds like a leak at the edge. You might ask Kenwood Service if this is a known problem. If it is, they might repair it, or ship you a new display. *sigh* -- Then again, this is still an Internet where the appropriately named Domino server It's not appropriately named; it should be called Lotus House of Cards. -- Steve Sobol, in response to Alan Brown |
