Programming your lock codes

The red light is an error code indicating that A component in the TV is failing and is not receiving correct voltage, which is causing the TV to enter " protection mode" and show an error code. Could be any part of the TV but I would start with the power supply and go from there.
Usually the error codes are not very useful and you would need to count the flashes and check a service manual for you model.

Here is some basic info on testing the power supply.
TV Power supply general info

Snap off the back cover (opposite where you punch the numbers) by pinching the sides and pulling off. Do not press a pen or anything into the small light, you do not need too. Just pinch and yank off cover. You will see a small light and beside it is a small SET button by the batteries, it is labelled.. Press this Set button for 2 seconds. The red LED will light on the front code side and beep twice to indicate you are in programming mode. Enter your current code that you want to change (factory set is 12345) and then press the button that looks like a little lock on the keypad. Enter the digits "10" and press the lock button again. Enter the new code (must be six digits) and then press the lock button again. The red light should go on continously for 10 seconds. The code should be effective.
Note: if you have problems like we did, you can also remove one battery and press the "set" button simulataneously when you reinsert the battery. This resets the factory code of 12345. Then you can start over. For some reason our old code was only 4 digits, but it would not let us reprogram a 4 digit code. It didn't work until we did a 6 digit new code.

Please follow these steps
Programming a user code
There are two ways to program a user code.
A 1. Press the Program key.
2. Enter the Factory Code. The green LED remains ON
while you enter the 5-digit user code of your choice.
After 5 digits are entered the green LED turns OFF.
(To enter a new User Code, repeat these steps.)
B 1. Press the red button inside the safe. The lock will
beep and the green LED will come on.
2. Enter a 5-digit user code.
(To enter a new User Code, repeat these steps.)
Keep your new user code secure.
For your records, please copy it here:
____ ____ ____ ____ ____
Programming a password
1. Press the Program key.
2. Press it a second time.
3. Enter your 5-digit User Code. The green LED remains ON.
4. Enter the 5-digit Password of your choice (any combination
except 00000.) After 5 digits are entered, the green LED
turns OFF.
(To enter a new Password, repeat these steps. To erase the
Password, press Program twice, enter your User Code and then
enter 00000.)

Battery replacement
Below When old batteries are removed for replacement, your Password will be voided; only Factory and User Codes will work. To
reestablish your Password, follow the directions above under
Programming a Password.
Key override
If your electronic lock fails or you do not have any codes
available, you may use a key override to access this unit.
1. Remove the battery cover, disconnect and remove the
battery holder.
2. Insert the skeleton key (second set of keys provided)
into the key hole inside the opening for the battery.
3. Turn the key to the right.
4. Turn the four bit key to the right.
5. Open the door.
Signals
Your electronic-lock safe communicates by means of several
audio/visual signals.
Red (Error) LED + three beeps indicates
one of the following:
1. You have pressed Program key out of sequence
2. You have entered an invalid code or password.
3. You have let 5 seconds or more elapse between key entries.
Green (Proceed) LED + single beep occurs
1. After entering each digit of Factory or User Code, or
Password
2. After pressing Clear key
3. After pressing Program key
Green LED only
1. Comes on after you enter a valid code/password and
remains lit during the 4-second period in which the safe
can be opened.
2. Comes ON in the Program User Code mode after you enter
the Factory Code and remains lit until you have finished
entering a 5-digit User Code.
3. Comes ON in the Program Password mode after you have
entered your User Code and remains ON until you have
entered a 5-digit password.
Yellow LED
Indicates low battery and will typically not turn ON until
battery has been in use approximately two years or longer.
Your electronic lock automatically performs a low battery test
during each lock use.
If a �low battery� condition is detected the Yellow LED will
come ON and remain ON during each subsequent lock
operation. (The lock will continue to function in a Low Battery
state, until battery failure.) The Yellow LED will turn OFF only
after three consecutive Good Battery readings or after the low
batteries are replaced. (Note: If the new batteries are installed
in less than 60 seconds the Yellow LED may come ON and stay
ON during the first lock operation before it returns to OFF.)
NOTE: It is recommended you replace the batteries after two
years, or when the yellow LED remains on.

is this a single red light? if so, it is a E code error. if there are 2, it is a overheating problem. if its 3, it is a general system error which could be a number of things which you need to figure out the secondary error code to narrow down the problem.
to find the secondary error code:
1. after the red lights start flashing, hold down the "controller sync" button.
2. push the "eject" button 4 times and count the amount of red lights that flash. the red lights will begin to flash rapidly. secondary error codes are only 4 numbers. 1 light = 1, 2 lights = 2, 3 lights = 3 and 4 lights = 4.
after you get the code go to this website, and on the right hand side of the screen under "Xbox Repair Guide" select your PRIMARY error code (1,2,3 or 4 slow flashing red lights). then it will ask you to enter your SECONDARY error code, which is the one you discovered in the steps above.
this will give you a very narrowed down idea of what is wrong with your console, and will give us "questions answerers" a better idea on how to help ya out!

Enter the 1,2,3,4 factory number.
When the door opens, immediately press all 4 keys are once and release.

A red light will come on. then enter new code. lamp will turn off.


to confirm the new code enter it a second time.
red light blinks, an error has occurred or your timing was off, so just start over with the factory 1,2,3,4 code.

Locksmiths recommend
two ways to program a user code.A
1. Press the Program key.
2. Enter the Factory Code. The green LED remains ON while you enter the 5-digit user code of your choice.
After 5 digits are entered the green LED turns OFF.
(To enter a new User Code, repeat these steps.)
B 1. Press the red button inside the safe. The lock will “beep” and the green LED will come on.
2. Enter a 5-digit user code. (To enter a new User Code, repeat these steps.)
Keep your new user code secure.

usually with 1 red light errors, there will also be an error that shows on the screen like e73, e74, e75, etc. You will need to first get your secondary error code.

then enter either the e-code from the screen or the secondary error code into the repair guide

Here are the Instructions I have to my older (Sept 1998) GV2000-A:

PROGRAM YOUR SECRET CODE:

Enter the 1,2,3,4 factory number.
When the door opens, immediately press all 4 keys are once and release. This will cause the red lamp to come on, so programming can begin.

Note: Avoid doing this in bright light.

Enter your new secret code. The lamp will go out.

Now immediately confirm your new Secret Code by entering it a second time.

If the red light blinks, an error has occurred or your timing was off, so just start over with the factory 1,2,3,4 code.
