Are you saying the lights/screen issue is with the base unit, or the handsets?

Thank you for the information.

This is a defect in the base unit.

It is quite common for them to go out, usually damaged by a power event (shock/surge, over/under voltage, etc), either through the phone line or the power line.

There really isn't much of anything you can do to fix it, beyond the reset steps you've already attempted.

The best option here is to either replace the entire system, or get another basic system (1-2 handsets) with a base unit that will be compatible with your existing handsets.

You could buy a replacement base unit (used) but it would cost you more than a new system, so it's not really economical.

I'm sorry there isn't a better answer in this case. Would you like me to help you find a replacement model?

Well all the new systems are a new format (yours is 5.8ghz) called DECT6

Your old handsets won't work with it, but it's worth upgrading because you'll have far better range and sound clarity than the older systems.

In my opinion Panasonic still makes the best systems, but you can also find them from Uniden (next choice) or AT*T

Similar to what you have now. You can buy a system with anywhere from 1-5 handsets, and most are expandable to 12 by buying additional handsets.

You mean when comparing panasonic models against other panasonics?

Or against other brands?

Here is an example: Panasonic KX-TG7645M DECT 6.0 Link-to-Cell via Bluetooth Cordless Phone with Answering System, Metallic Gray, 5 Handsets

It's a 5 handset system, for around $100

Not really, they're all going to be the same quality.

The difference is in features, some will have a built in answering machine (if you have voicemail from the phone company, you don't need this) and some have the link to cell function I just mentioned. This lets you use the cordles phones to interface with your cell phone, using your cell minutes for free long distance.

One other piece of advice,

If your'e getting a new system, and plan to expand, get the biggest one you can to start with. You won't pay much more for a 5 phone system than a 2 or a 3, but adding extra handsets can be $40-50 each, so it's cheaper to get it bundled when you start out, than to add later.

You really can't go wrong with an of the panasonic dect6 systems. I'd recommend buying one on amazon (like the one I linked to earlier) just because they have a good return policy if anything is wrong with it right away, free shipping, and no tax, and usually better pricing than local shops.

Beyond that, if you have a large home, there are some panasonic models that have a "range extender" that can plug in to an electrical outlet on another floor or far off area of the home to boost the signal.

But it only works with certain models, so if you think it's something you may want to add later on, get the compatible phone system now.

Here is an example: Panasonic KX-TGA405B Range Extender for Cordless Phone Systems

It will list the compatible models on the same page as the extender listing.

You're very welcome.

If you have any other questions, let me know.

Otherwise, please remember to provide positive feedback for my answer (one of the smiley faces) so I receive credit for my time working with you.
