Can somebody help me with the code?

[Voss]

I tried several code calculators for my very old car radio, which i found in garrage, but i dont remember and still cant find the real code! Now, after many attempts on the display i see only "- - - -" and all buttons are inactive! Hope that this player is not blocked forever already.. Now i will try to leave it on for the night, but tomorow if i will be able to enter the code again i will need the right one! So please if someone can help me with the real code please do it! THANKS IN ADVANCE!

The player is an old BLAUPUNKT, kessete player:

Thanks for your answer, but seems the player is already blocked bcose it wont turns on! The power button lights up for 1 second and turns off. Last night i leave it on power and display "----" but today it wont turn on anymore? What to do now ?

The unit is out of the car and i use ongrid power adapter 12V/2A.. But the problem still exist! yesterday i was able to see "CODE" and input numbers, but after all my try outs - today everything is inactive, only when i press the power button he liths up for 1 second and goes down..
