    The red light on the phone continues to flash, even though there are no new missed calls/caller IDs to check.

I hope this will help. I had the same problem with the message alert light not turning off. I have phone service through the internet. I would clear messages from my base unit and alert would continue to flash. I went into my internet message center and found a few old messages there. Why they got there is beyond me, but after clearing them my alert light went out and stayed off. I disabled messages to internet inbox and now it flashes only when I get messages to my base unit until I listen or clear them. Easy fix to annoyance I've had for some time.

Hi I am hoping you can help me. I own a Siemens Gigaset A58H handset which up until 48 hours ago has been working perfectly. One day, the voicemail light indicated I had new voicemails and so I went to...

You need to find your manual to the phone in case you need to reset the phone.
When flashing Base like that, it has lost connection to the base charging station. It can be the power to the base unit or the phone cable that is faulty.
In any case the phone cannot connect to the base unit, so my advice would be to check the base unit (normally also the charging station), and make sure that all cables are connected and it is turned on.
It sounds like a bit of a dummy advice, but in my 17 years of experience, it is nearly always a cable problem when described like yours. It can be something as simple as someone unplugged the unit to vacuum or something like that and forgot to plug it back in.

If that isn't the case, then see the first line I wrote. Then you might need to reset the phone. The few wireless phones I've had, it would include either letting it run out of power or removing the battery and then a combination of buttons you had to press. But that would be mentioned in the manual.

Hi my backlight has turned off permanently it

There is a possibility that your front panel board has lodged inside some dirt , sweat or water which is causing this erratic operation. it ieasy to open out the front panel and use a good swab dipped in volatile spirit to clean off all the dirt in the panel . check if there is any corrosion in the front panel. remove and tighten the front panel and reset . if this solves the issue you are saved from a costly repair. Try out. Good day.

The in use light is on, All phones are turned off.

Did you recently replace you old phones with these phones? Maybe the old handset of the phones are interfering with them...remove batteries from old handsets, as they may be searching.

My pantech duo phone doesnt work anymore!

From the way it sounds, mine started doing this yesterday. Everytime i turn on the phone, theres just a backlight and nothing else. well the only way i noticed to get it to work, atleast until i can get a new phone is, to leave it slid up because it wont do anything if its closed or slid sideways. And while it slid up, I either have to call it from my home phone or recieve a text message. I'm not sure why but that made the screen come on so I could atleast check everything. It doesnt always work but it does most of the time. I hope this helps. Just play with and figure out what it takes to get your screen on. I'm not sure how to permanently fix it though.

Lg cell phone vx3450

This is an old post but in case anybody searches and finds it...The infamous "car kit" mode on LG phones is a problem I had. Your service provider will claim the phone got wet (they will look at indicators in the battery compartment and on the battery itself that turn blue in the presence of moisture. Trouble is, they will eventually turn blue just from humidity even if the phone wasn't given a bath). Search the web; there are one or two forum threads with many suggested solutions (such as resetting error codes in the service menu, scrubbing out the battery connector with a toothbrush, plugging/unplugging the actual car kit connector, etc.). None of these suggestions gave a permanent fix (YMMV) for me and I eventually bought a new phone.
