Must be the fall seasonŠ.. My M100 just did the same thing while in use on A/C power, the picture looks almost identical apart from the white block and it only has two bands.
The NiCd has been replaced and a cold reset etc did not change the locked condition. It seems to be stuck in that screen state. It looks like the screen is not getting reset when powering up, the lack of beep generally means the boot process is locked waiting for the screen to respond. Debug time again it would seem :( On 27/9/19, 6:53 PM, "M100 on behalf of Eric LK" <m100-boun...@lists.bitchin100.com on behalf of tr...@lefauve.org> wrote: >Hi, > >I usually use my M100 at least once or twice a week but I was away for >almost a full month, and when I turned it on yesterday, it decided to >take a break :o( > >When I turned it on, it was OK for about 3-4 seconds (the time for me >to look at the menu clock, and to check on my watch it was still on >time) and then the screen become white with a few black lines (notably >the first and last lines). > >I pressed a few keys, hoping for a refresh problem, and then used the >RESET button, which cleared the screen (I could still see the white >pixels when turning the contrast dial all the way up though). >I tried a few time to power OFF/power ON, or to do a cold reset >(Shift+Break+RESET) but the result didn't change: Every time I got >either a totally white screen or a white screen with a few black >blocks (here is a picture: >https://eur02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fpics.lefa >uve.org%2FM100-Blocks.jpg&data=02%7C01%7C%7C0a41c556408b42a62d7008d743 >b6a089%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637052323959256042& >;sdata=qhcaLPO7W3w2gT4TwJuQPxvLYYc3lm9H%2F9aP5H4tvDs%3D&reserved=0 ). > >I tried to press ENTER + beep + ENTER to check if only the display was >affected but I got no beep. > >I also tried to remove the REX but it didn't have any effect at all. > >I checked the batteries (5.5V) and tried new ones.
