Kyocera e4710 Plug in charger and the red lite blinks twice then stops and phone will not turn on

You need a new charger.

Step 1 Charge the Bluetooth headset battery. The headset is fully charged when the indicator light turns off. Step 2 Unplug the charger and check the indicator light to ensure that the headset is turned off. If the indicator light is on, the headset is on. Turn off the headset by holding the multifunction button (the button in the middle of the headset) until the indicator light blinks red and shuts off. Step 3 Press and hold the multifunction button until the indicator light blinks red and blue to place the headset in pairing mode. Step 4 Turn on Bluetooth on your phone to start searching for available devices. When the search is complete, a list of available devices appears on the screen. On many phones, the Bluetooth options may be found in Settings. Step 5 Select the Kyocera Bluetooth headset name from the list. The phone prompts you to enter a passcode. Step 6 Enter "0000" using the phone's keypad to finish connecting the headset to your phone.

I experienced the very same problem twice.
The red led would either stayed on all the time when charger was connected or it blink whenever I'd push the power button on the phone, but the phone would not turn on.
My solution was to unplug the charger, take out the battery and the sim, keep them separated for at least 48-72 hours, then put back the battery, connect the charger again (don't use your computer's usb port, use a real wall charger, preferably the original one), turn on the phone.
If it doesn't turn on immediately, let it charge for a few hours and then try to turn it on.
I revived this phone twice using this method, first time I thought I was just lucky, but apparently it's reproducible.

Hope it works for you too.

I had the same problem but I held the power button for about 30 seconds or until it stopped blinking then I hit the power button again shortly after then it worked. I hope this solves your problem also.

well one thing that can cause this is major damage in the charger or the ds lite

Plug your phone in the charger and then take out the battery and put it back in. Or you can push the button to turn your phone on and then plug it in while it is starting up and it should catch on and start charging. It is definitely an annoying glitch, but a simple solution

Put a new battery in it.
also try another charger, the charging port could be a little messed up.

I have xfinity Comcast cable connected to my Disney's CARS TV/DVD combo. I did not have a remote for it because I bought it at yard sale without it. I used Comcast's remote control. I followed their "Searching For Your Code" instructions. #1-turn on your TV. #2-hold SET till red lite blinks twice. #3- enter 9-9-1. The red lite blinks twice. #4-press nd release the CH+ key until TV turns off. #5-once it turns off press SET key nd red lite will blink twice. #6-Now u have locked in ur code. Press power and TV should turn on. Then CH+,CH-,VOL+, and VOL- should work for ur TV.

You can go to your carriers retail store and use one of their chargers for free. Then you can determine if it is the phone or the charger.

I had this same problem and all I did was to unplug the DC adapter at the phone and plug it back in after a few seconds. The solid charge light came on immediately, like usual. I let the battery charge for several hours before using the handset again.
