LED display is disappearing

The characters on the LED display of my Siemens Gigaset 8825 are losing clarity. They seem to be "crumbling." Is there anything that can be done to improve the situation?

Yes it is a common problem with those displays (but it is fixable), and it actually stems from a "generation" of displays that were used in Siemens, AT&T, Toshiba, many of the major players in the industry. Ask anyone who has owned a Sony cordless, or a AT&T 9000 series cordless, or a Toshiba FT user or Panasonic digital cordless user. Many will tell you their screens failed too, but on handsets many times its from corrosion created by moisture damage. This was late 80's, early 90's design, which of course was manufactured into the 1990's generation of phones that had LCD's. Its not just isolated to this model or Siemens, and while the LCD is a "achilles heel" so to speak for this model, In my opinion, the features and quality of the machine itself outwieghts the drawback of the display (provided you can replace it with a new display cost effectively), which you can if you google Siemens Cordless Repair and go to the first few unsponsored links. The other writer brought up a good point with the question of repair investment vs. replacing with new. Granted, prices have come down on cordless telephone equipment when you go to Walmart, Best Buy, etc.., and with the newer bandwidths you can get a 5.8GHZ or DECT 6.0, and bigger is better right? Well in cordless, frequency wise bigger is not better(depending on your needs), in fact when it comes to reception and range you cannot beat 900 MHZ or a similar frequency. However, 900 MHZ is not secure, where a frequency hopping spread spectrum running at 2.4GHZ or higher is. But each phone has its own benefits and drawbacks, regardless of the unit and depending on an individuals needs. Nevertheless, I still feel you get what you pay for (today and five years ago), and from my perspective the newer products have less features people like to use and they each have their own "achilles heel". Siemens phones were not meant to be throw aways, and you will be hard pressed to find another system with the same combinations of features. Just walk in any retail electronics store and tell them you want a cordless telephone that you can register to multiple bases (one Siemens model will communicate with up to 4 bases), to extend your range. You won't find one, they don't make them anymore. I use it daily, and would be hardpressed to change, except I do like the Panasonic model that has inexpensive cordless video cameras you can register and mount around your property. Nevertheless, your Siemens phone is fixable, don't toss it out.

Thanks to Chuck; I read this as a "solution"---design flaw makes sense to me--you're right, too, about newer systems being available for more reasonable prices than this unit sold for when it had no competition for high power two-line reception. Many thanks. I'm glad I discovered this site. Merle

I have had a couple of these systems over the years. When I've been searching on the internet to buy the second one, I found what you are experiencing is a pretty common problem. I bought the second unit for a second home and it was advertised as having some of the pixels missing on the display. when I received it, all of the pixels were present!! However, over time, they are slowly disappearing. I think this must have been a component or design flaw in this particular model. Today, I found the original system that has been off and stored for a couple of years. When I put it away, the display seemed to be perfect, but today I noted 4-5 pixels on the right side are now gone. I dont know a solution other than instead of investing money in fixing it, to purchase a brand new system. The prices are pretty good now, especially if go to Costco or Sams, or just searching the net for a good price on the model you want to buy. Chuck

I have the same phone system, and *think* you may be able to fix the problem by adjusting the amount of rings before answer on each unit. This assumes there is an auto answer system engaged. Hope that helps some.

Led display disappearing

If you cannot do without your phone and your display is going bad, you will have to decide which is the best option for you. You can get a replacement base and recycle your old one to save money. You can get a replacement base then have your old one fixed so you always have a backup ready when that unexpected lighting storm passes through. Or, if you can do without your base, you can send it in for repair. And lastly, if you have fixed electronics equipment before, and/or are willing to risk messing your unit up entirely, you can order a new display and install it yourself. Siemens did not abandon their cordless product line like a few people have mentioned in other blogs, they merely directed it off to an independent facility to provide future service and some parts for the do it yourselfers. You can go to their website to find the repair service facility, or google Siemens Cordless Repair and click the first few unsponsored links.

Power supply gigaset 8825

The power supply for the 8825 base is to be 13 volts AC, rated at 850 milliamps or higher. You can go anywhere from 13 up to 15 volts without hurting the unit, and a higher current rating is even better. We actually make them ourselves through bulk purchases of varieties of power supplys. Your next delimma will be the plug size, it is a pretty common size, most universal adapters will have the right size of the outer and inner connections.
