My Studio 6 was dropped on its back side and now it wont turn on anymore . the screen went purple with lines on it after it drop. what can i do to got it to turn on?


I would say the screen is damaged and will need to be replaced. They can cost $100+ and it may not be economical to replace.

Unlock a frozen screen on a samsong s5


More details please. Is it really "frozen" or just doesn't work?

Keys stuck in the ignition. Wont turn or come out.


There is a possibility that the steering lock is leaning on one side, such as when the front tire rests heavily a curb. Try moving the steering wheel repeatedly from side to side ( as far as it will let you go), while at the same time trying to turn the ignition key.

It wont turn on


On TI-83 Plus and TI-83 calculators that have the newer flat screen (as opposed to the first generation TI-83 with the tilted screen):

1. Open the battery compartment cover
2. Install known working batteries
3. Using a voltmeter, insert probe ends into the holes right beneath the 2 center batteries and touch the circuit board on either side. One is a (+) side and the other is a (-) side, so both must be touched. Be careful to ONLY touch the copper square of the circuit board. If your voltage reads 0 or very low (1-2 volts) proceed to step 4. If your voltage reads about 6 volts, your problem lies elsewhere.
4. Using a voltmeter, insert probe ends on the bottom of the 2 outside batteries where the springs are visible. If voltage reads about 6 volts, proceed to step 5. If voltage reads 0, your problem is that the springs are not making good contact with the batteries due to corrosion or weak springs. You will need to clean them or get donor parts. Find a calculator with a broken screen that comes on and swap the back covers. Details on how to remove the back cover further on.
5. Using a T6 torx electronics screwdriver remove all 6 screws on the back and using a small phillips, remove the backup battery cover.
6. WARNING! Disassembling your calculator can cause unrepairable damage. Only proceed if you have no other options! Using a small flat electronics screwdriver, pry into the case on the side about 4 ridges up where there is a small hole. Pop both sides open and break case away from the bottom to the top- NEVER FROM SIDE TO SIDE. (Going from side to side can damage the I/O port.)
7. Look at the copper squares at the bottom of the board. You can see where 2 springs make contact from the back cover. Often this is dirty, corroded, or the springs are weak and not making contact. Clean this area with alcohol and gently scrape away any oxidation.
8. Put calculator back together and test. When a calculator will not turn on, this is likely the culprit.

I have fixed several calculators with this method.

Screen turn Black


Put your phone in a bag, put it in the freezer...
It will might work until it warms up again..

It might be your screen, it might be the body of the phone...

for the screen...

get a TORX 6 screwdriver

take it apart
Google for V220 take apart/ disassembly

WIggle the tiny flex cable connector
near the hinge.. still no luck ????

Buy another V220 on ebay

gently take the phone apart and sub in the whole
screen shell and front of keypad.

DO NOT TRY TO remove the screen from the body section..
you will destroy to the teeny tiny flex cable.

Still problems?
then its the body... your phone is useless
undo what you did, re-assemble the parts phone,
learn how to flash the spare phone..

USB adapter
Motorola P2K drivers for XP
Motorola or other flash tools
enter phone service mode
connect phone to pc
flash back to V 364 firmware
run unlocker
flash unlock firmware
enter dummy unlock
reflash to v365 firmware

More details googling above and reading lots

OR.. Pay $10-20 have someone else do it...

I wont, too much work...
