Siemens 2420 Phone System

Phone base display isn't legible. Partial characters are showing, so I can't program the system.

    I have the same problem. I have already replaced the system but would like to fix and donate the system to someone else.

  • Anonymous Dec 10, 2007

    I purchased my Siemens 2420 in February of 2000. Beginning in 2005 the display on the handset began to degrade, making it somewhat harder to read. It has now reached the point where it is barely legible.

The problem with the displays going bad is quite common with this model and other manufacturers (not just Siemens) that useds the same "generation" of displays that came out in early,mid 90's. The only option you have is to send it in for repair to have the display replaced (they are not plug in type displays possible for a do-it-yourself fix). It is totally unrelated to the power supply, but the pixels will come and go so it could have been a coincidence that they reappeared with the new power supply. Here is a link to the Siemens website where you would select the Gigaset folder, and it take you to a FAQ page where you can find tips and repair service options. http://kb.efficient.com/display/1/index.asp?c=&cpc=&cid=&cat=&catURL=&r=6.295413E-02

I'll find someone with a multi-meter and let you know! You are correct - 12v 400 mA

I had the same issue a while back and I believe a new power supply fixed that problem. If you know anyone with a multi-meter and they know how to use one they can tell you if your power supply is bad or not putting out enough voltage. I believe this system requires 12 volts and 400 milliamps it will say on your current power supply.

System pin # reset

There is a way to override and reset... I think you need to press *67# when in the system pin area via menu. Confirm this first though. There is a way to do this though- then you reset it to 0000- google it and you will find the answer-

Gigaset 2420 Siemens

You may have the wrong or defective power supply. Or, that problem is common from getting a power surge and the unit will probably have to be sent in for repair, sorry.

Siemens Gigaset 2420 corded unit resets when calls received

OK, here's what happened. I had the same issue of the phone resetting when a call came in, I thought it was a power issue and through some testing it was not. Here's the fix...Menu \ system settings \ enter pin (if you haven't changed it it is 0000) scroll to factory default and reset. This fixed the problem somehow for me, make sure to write down any impotant messages because it will erase everyting (silly me). I hope this helps.

Siemens Phone

I just replied to a similar post. This is a common problem, not only with the Siemens but most all manufacturers that used this design of display on many different devices. And in this case, the display connections are pressed on with a special machine and can't be replaced by a do it yourselfer. Sorry I can only recommend sending it in for repair.

Siemens Gigaset 2420 Desk Staion LCD Display

That is a common problem with those types of displays, they are sensitive to heat, cold and any movement. They were used by Siemens, and almost all the other manufacturers during this time period. Unfortunately on this particular model, they are not soldered in, they are pressed on by a machine. So if you don't have a Zebra cable press machine ($1000's), and a brand new display, you can only resort to sending it in for repair. Sorry.
