Sanyo MM-8300: ALL the keypads are frozen and won't work. Any solutions?

My phone just decided to freeze and I tried taking out the battery and putting it back in but that doesn't work. The phone didn't power on for a couple minutes after I took the batter out and now the keypads don't work at all. Does anyone have solutions to fixing this problem? Thanks!

One thing you could test for is a thermal-fault in the phone's circuitry. To do this, you put your phone in the fridge over-night then, turn it on the next day and try the keypads while it's still cold from the fridge. If that doesn't help and you're brave enough to venture into the inner-workings of your phone to attempt repair/cleaning, you can read my post here- keys won't work on sanyo mm 8300 phone.
Hope this helps, TechnoWolfy.

Phone has switched off and wont restart

try taking the battery out for 5 or 10 seconds then put battery back in. Hold the red power/end key down. If that doesn't work see if it will power on while charging.

Is there another way to power on a droid 2?

It's happened to me a few times recently. Simply taking out the battery, then putting it back in usually does the trick. Try plugging in the charger with the battery in. If that doesn't work, take battery out, plug in charger, then put battery back in. Hope this helps.

I connect the charger of my htc hero. at first it was charging. after an hour i noticed that it stopped from charging. when i turned on my phone it didn,t open.

Open the back cover , take the battery out . Press and hold the power button without the battery . Put the battery back in . Try to power it on .
If that doesnt work try below steps , ( note : you will loose your data )
Power the device OFF. Press and hold the HOME and Back Arrow buttons. While holding these buttons, press the End Call button once. Release the Home and Back Arrow buttons and press the Trackball to execute the Hard Reset. The device will reboot once the process is complete.
Thumps for my solution if it works .

My phone vibrated and when I looked at it the screen was white i tried turning it off and taking out the battery but the screen is still white.

Try taking the battery out and pressing the power button for 30 seconds to completely discharge it, then put everything back together and try to turn it on. If that doesn't work, there's not much else that you could do unless you have warranty, or get a new phone.

Freezes and rebooted. Mostly freezes

Hello and welcome to FixYa;

You didn't specify what type of LG phone you have;

You can try rebooting it as an option; or (cycle it once a day).

Turn phone off. Take off cover; take out battery, sim card (if your model has one);

keep them out for a couple of minutes;

replace sim card (if your model has one), replace battery; and turn phone back on.

You could try 'resetting' your phone; but all models are different and you didn't give me the model number.

Try this and see if it works for you; also, when you take battery off, you can try to gently clean the battery terminals for debris. A phone will reboot if the battery is gunked up or not making a good connection.

Sorry i couldn't give you more to go on with the information you provided. Hope that helps.

I have a HTC D2 for a year, phone out the blue started acting wear, freeze, over heat, **** all the battery juice. I had done everything software update, manufacture reset and problem still continue

If you have already tried everything then it is probably the battery which is causing all that problem.
> Take the battery out and see if its connectors are are clean.
> Clean it with a soft dry cloth.
> Clean the insides of the phones where battery is to be placed.
> Put it back again and boot the device up.

If it doesn't help try a new battery and see if the problem remains the same.
Even if that doesn't help I believe you'll have to take your phone to the nearest Sales and Service Center.
