Grundig tv factory reset - Grundig GU19WDVDPCX 19 in. LCD TV

Hello Petar,

To reset the pin code on your Grundig TV 32 GEH 6600B, you can try the following steps:

1. Turn on your TV and press the "Menu" button on your remote control.
2. Navigate to "Settings" and then select "Child lock" or "Parental control."
3. Enter the current pin code (if you know it) using the number buttons on your remote control. If you don't know the pin code, try entering "0000" or "1234".
4. Once you are in the parental control menu, select "Reset" or "Clear all" to reset the pin code.
5. Confirm that you want to reset the pin code by entering "Yes" or pressing the OK button on your remote control.

If this does not work, you may need to consult the user manual for your specific TV model or contact the manufacturer for further assistance.

I hope this helps!
