Unblock locked grundig tv t55 1020


try 0000 reset

Other wise
This is how its done but you will need A repair shop to do it.

Place set in to protect by entering any sequence of numbers 3 times,
Connect a 390ohm resistor between w129 (ground) and pin 56 of the micro,
Press button 7 on the remote for a minimum of 6 secs.
And thats it unlocked.
Sorry its not a simple fix.

Plse help i have a grundig model 3680 serial 341010a0087248 need code plz?


When you disconnect your battery and then reconnect it again, it disables the radio. This is an anti-theft protection for your car radio.
The enable your radio the activation code is in your vehicle owner's manual. If you do not have this code you need to go to your vehicle manufacturer's service centre and get them to enter this code for you.

Tv protection


Hi.

The set is expecting a pin number to be inserted.

If you dont know or cant remember pin do this.

USE REMOTE CONTROL AND BRING T.V OUT OF STANDBY,

SCREEN REQUESTS PIN CODE,

PRESS STANDBY, PRESS NO. 7 BUTTON FOR 6 SECONDS, THEN IMMEDIATELY PRESS STANDBY (THERE MUST BE NO DELAY BETWEEN LAST ACTIONS).

Do this to the letter it should sort out your problem.

How to unlock Grundig T55-1020 pincode


Hi.

Unfortunately there is no magic code that you can enter to undo the pin code lock.
This is how its done but you will need A repair shop to do it.

Place set in to protect by entering any sequence of numbers 3 times,
Connect a 390ohm resistor between w129 (ground) and pin 56 of the micro,
Press button 7 on the remote for a minimum of 6 secs.
And thats it unlocked.
Sorry its not a simple fix.
