Re: How to unlock Grundig T55-1020 pincode


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.

Grundig TV - Colours all mixed - still have fullpicture

Hi rosscop

You have a magnetic interference problem. First, have you put any magnetic objects like speakers near the set recently. They will cause this. Turn the set off at the wall and wait for 15 mins for the PTC device that turns on the degauss coil to cool and operate. It is the loud burst of hum you here when you turn the set on from cold.

0083efa.jpgThe PTC is a postive tempeture coefficient that allows alot of current to flow at first, heating up as it does, and then slowly less current as it heats. This is why you need to turn the set off and let it cool. If the problem remains The PTC may be faulty allowing too much current to flow and upsetting the magnetic flux about the tube. If you dont have the skills you will need a technician to sort it out for you.
