Samsung katalyst will not turn on or charge it just brings up the katalyst screen and turns off

Sometimes its the charging port that breaks and won't allow it to charge, if that's the case, you'll either have to live without it for a few days, or buy a new phone.

But if its the battery, you can buy a new one online at many different stores, try searching around to find the best price.

Reset katalyst sgh-t739

I did additional research and found the appropriate code which worked immediately.

From the standby screen enter:
*2767*3855# You had better mean it. Once you enter the # there is no turning back. Your Katalyst will be returned to its factory condition.

"mwright35" this is exactly not your same case but it is definetly the same than "remembermeil."

I got my phone wet and aftre drying it turned on but the on/off button was not working. My phone got discharged and then I thought I had lost my phone. Here is what I did and then my pone turned on, but I am not 100% positive this will work since I don't wanna try again.

Solution:

Take a part the phone, including the "motherboard." This is very easy to do, you only need a small screwdriver. Here is the important part: Unhook the motherboard from the LCD display. I think that when you do that something resets itself. After, when you put it back together including the charged battery and everything, the phone will turn on by itself.

RED, GREEN, BLUE AND WHITE HORIZONTAL BARS APPEARED ON MY SCREEN???

hey, i had the same problem and i fixed it. i took the battery out and saw the 4 golden tabs behind the battery. there was two tabs that u could pull out. i lightly pulled them out a little bit. the problem was that the tabs wouldnt hit the battery to charge it. thats why it put the tri colored screen on the front. also my charger fit into the charging hole in the phone, but it had to be moved around to much that it did not fit exactly. I have been rough with the charger so it moved the inside of my phone around. i put the charger in the phone and moved it around gently around untill the light lit up on the front at the top by the word at&t. after it was completly charged, i turned it on and it worked perfectly. i hope this helps in whoever may have this problem because i know it sucks!
Thanks
