Re: Keeping the 857D Screen For Long Life
开云体育I just powered mine up to do an informal test. On first power, 17 of the pixel columns were blanked out. Over a period of about two hours, ten of them self "repaired" or "healed". This was with rig indoors at normal room temp. No transmitting, just power on, sitting idle.? I'm going to keep it on for the remainder of the day to see if any more columns come back alive. Is this an anomaly or is this what's seen on most with the zebra problem? Just curious...

Re: Keeping the 857D Screen For Long Life
开云体育This issue has been discussed over and over for the past few years. IMHO it seems that you are more likely to have the Zebra stripe issue if your radio was mounted in your car under hot sun conditions. Like any “rule” there are exceptions. If I were going to use my 857 in my car I would take it out when not in use based on the volume of anecdotally reported trouble issues.. My 857D has been housebound for 10 years or so with not problems. ? Tom K3TVC ? ? ? From: [email protected] [mailto:[email protected]] On Behalf Of charles colton

Re: Keeping the 857D Screen For Long Life
开云体育I do notice on my head unit, (where it once was installed in a truck for about three or four years), I do have some zebra stripes, but after the rig has been on for about an hour or so, some or most disappear. It's random though so each time I get slightly different results.?

Re: Keeping the 857D Screen For Long Life
I had my early 857D in and out the car for 3 years in the dry and very cold climate of Edmonton Alberta and in the humidity/rain of Victoria, British Columbia. No issue with the display at all, so I don't know what some folks are doing to help their displays go wonky. I've been lucky it seems.

Re: Keeping the 857D Screen For Long Life
开云体育I suspect stripes appear for several reasons. ?I've been baking my '857D through four car changes over the years, but have always shaded the front seat area with a windshield screen. ? The display is still normal after 12 years. ?Bought new in January, 2010. 73, Kent K9ZTV On Aug 12, 2022, at 8:45 AM, Zack Widup <w9sz.zack@...> wrote:

Re: Keeping the 857D Screen For Long Life
It's not only heat.? I had the zebra-stripe problem appear on my 857D after a few years.? The rig has never been mobile, or even portable.? It's lived its life in an air conditioned house, and is kept covered up when not in use, so sun never shines on the screen.? In my case, Yaesu replaced the screen for only $70 - but that was several years ago.

Re: Keeping the 857D Screen For Long Life
Yes, my experience is that the heat alone does it. I left my unit in the car quite a bit, covered by a box or cloth so people looking in the windows wouldn't see it (nothing here to steal). No direct sunlight was on it but it got quite hot. The zebra stripes appeared and I replaced the display. I got one from Ham Radio Outlet. Now I don't leave the rig in the car for extended lengths of time and the stripes have not reappeared. 73, Zack W9SZ On Fri, Aug 12, 2022 at 4:36 AM mikemm58 <mmcauley@...> wrote:

Re: Keeping the 857D Screen For Long Life
My ft-857d was installed in my vehicle for years. It developed stripes. I then removed it from the vehicle and did some SOTA activations during a Scottish winter, with minimum temperatures of -5°C. The zebra stripes disappeared. Two years later and they haven't reappeared. Yesterday I used the radio portable in 26°C heat on a summit. All good!
Now, I'm not advising anyone to stick the head unit in a freezer, but I think the cold temperatures cured mine. 73, Fraser MM0EFI? |

Re: Keeping the 857D Screen For Long Life
开云体育If the screen problems are a result of direct UV rays shining g on the display, I could see that helping.? But I was under the impression that the problems were from just high heat levels.?

Re: Keeping the 857D Screen For Long Life
开云体育I do concur with both comments about display
is mostly with radio which have been use in a car. I bought mine in 2012 from a German fellow,
with the guarantee that it was never use in car, as the zebra
problem was already known. 73 de Thierry, F4GVO Le 12/08/2022 à 03:46, KE5EOT a écrit?:

My understanding is that the zebra stripes issue tends to occur mostly in rigs that have at some stage been installed in cars where they have been heat affected, but perhaps I'm wrong.? I just had my screen replaced here in VK by a guy in Melbourne who specialises is Yaesu repairs and it cost me around $250AUD.

Keeping the 857D Screen For Long Life
First, I have a perfectly fine working Yaesu 857D, screen and everything else.? I love it.? I have read several messages over time that people had a failure of their 857 screen and were looking for a replacement. I wonder?? Are there things I can do to lengthen the use of my screen and hopefully prevent failure? I Could: - Use a certain color which stresses the screen less or more? - People who specialize at replacing the screen if it fails with "Zebra Stripes" or other problems? ? Sure would would be nice to lengthen the life of my 857D, there are no others like it. Thanks, Peder, W7RPK ? |
