Samsung T 809

If the phone lights up when you plug in the charger it is probably the ribbon cable that flexes every time you open the keyboard. About 25 bucks from cellphonerepairshop.com. Be sure to flip up the little latches on the flex cable ends before attempting to plug or unplug the cable ends.

I will try and keep this short. I have a Motorola Razr (puchased in the USA..... this will make sense later) and I lend it to my brother when he visits me from Canada. (Roaming charges for Canadians using their phone in the US is insane) He too has a Motarola phone that he brought with him. The Charger that he brought with him was for a Canadian phone. Apparently, you cannot use a charge for a Canadian phone, on a USA contracted phone..... I'm not sure why, but it is the case. He attempted to charge my USA phone with his Canadian Charger and the screen went blank. The phone was still on and could even receive calls. Even when the calls came in, the screen still remained blank. I won't bore you with any more details.
Here is how I fixed it:
- Unplug phone from Canadian Charger
- Take the battery out of the phone.
- Plug in USA built charger (without the battery in the phone)
- The phone attempt to charge
- Screen should turn on. Wait till screen indicates (Cannot charge battery)
- Plug battery in.
- Hold down power button to turn on the phone.
- Phone should be in working order.

I don't claim to be an expert. This may only apply to my particular situation. Hope it helps if you happen to use the incorrect charger. Take care.

what is the one you are plugging in..a charger?if that so that your fon's screen flashes when plug in and doesnt turn on when you will not plug in the charger ,then the problem is 99% your batery.replace it.

try to change the battery.

If the phone is unable to turn on, even if the battery is fully charged it really needs service.

Take your sim car out and try using these codes to reset the phone.
*2767*2878# and *2767*3855#

Your phone software could also be corrupt.
If you go to samsung you may be able to update the firmware in the phone over the internet.

If all else fails have the phone re-flashed by a technician.

Hi all,

I had simmilar problems ie screen ok when closed but fuzzy when slid open, screen going blank etc.

I replaced the flex cable that connects the screen to the main board and the phone now works perfectly.
