How to unlock my Grundig SE 7270 TV?

Asked by tilc (121 points ) December 20th, 2009

I just bought a GRUNDIG SE 7270 DOLBY TV to my parents, and I was browsing around the menu, and I went into something like this: “Dealer’s menu”, and I’ve seen the opportunity to write there 4 digits, but after that the menu was frozen. I turned off the TV, also unplugged, but when I turn it on I just get a blue screen and it does not do anything for any button I press on the remote controller. It seems like I locked the TV, right? I’m so upset…. please help me, how to unlock it. Thanks in advance!

I noticed there are service manuals available on line (as opposed to user manuals) One was for sale as a PDF download for $15, one for $10. I used the search term “Grundig SE 7170 manual”

Thanks, but I don’t want to spend money on pdfs right now, just need an answer…

does the tv have any buttons on it or you try only via the remote?

no reset button or something like that on TV, just volume and program up/down button

another solution:
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.

another solution that work on older grundig models:
Try the following:
Arrow right
Arrow left
Arrow down
Arrow up
Press ok button

If this doesn’t work, try the code 7038 and press ok button.
