Hi need code for ancient centrex tv for universal remote help aaaaaaaaaah

Centrex is not listed with URC04110 universal remote coldes. But you can search and find the code for your device with this remote control. I'm not sure will it work with your old Centrex TV. Anyway try. Wish you the best.


If your device does not respond to the remote control after trying all

codes listed for your brand, or if your brand is not listed at all, try

searching for your code. For example, to search for a code for your TV:

1. On the remote control, press TV once.

2. Press and hold SET until the LED blinks twice, then release


3. Enter 9 - 9 - 1.The LED will blink twice.

4. Aim the remote control at the TV and slowly alternate

between pressing POWER and TV. Stop when the TV turns


NOTE: In the search mode, the remote control will send IR codes

from its library to the selected device, starting with the most popular

code first.

5. To lock in the code, press and hold SET until the LED blinks

twice, then release SET.

6. To search for the codes of your other devices, repeat steps 1 through

5, but substitute the appropriate device key for the device you are

searching for.


If you have set up the remote control using the Searching For Your Code

procedure, youmay need to find out which four-digit code is operating

your equipment:

For example, to find out which code is operating your TV:

1. On the remote control, press TV once.

2. Press and hold SET until the LED blinks twice, then release


3. Enter 9 - 9 - 0.The LED will blink twice.

4. To view the code for the first digit, press 1 once.Wait 3 seconds,

count the LED blinks (e.g., 3 blinks = 3) and write down the number.

NOTE: If a code digit is "0", the LED will not blink.

5. Repeat step 4 threemore times for remaining digits.Use 2 for the

second digit, 3 for the third digit, and 4 for the fourth digit.

6. To check for codes of other devices, repeat steps 1 through 5, but
substitute the appropriate device key for each device you are checking.

Locked centrex television

I did research online and no luck. It seems that that company is no longer in buisness. I would think if you have the original owners manual there should be instructions to unlock the TV or maybe a phone number to call for support. I know that is the case with most brands sold here in the states. Good luck.
