After weeks of scouring the chat threads and trying to figure out the solution, I finally got a response from panasonic. I have decided to post a solution instead of a problem - as I know i can't be the only one that has had this problem.

Thank you for your inquiry. You will need to reset the television.

To reset the television hold the volume - on the television and menu on the remote simultaneously until self check is displayed.

Unplug the unit for about 30 seconds.

Reconnect the unit and power it on and complete the first time setup.

This should resolve your issue. Please let us know if further assistance is needed. Thank you for contacting Panasonic.

SOURCE: child lock

From the main menu choose "Parental Controls;" it's option six.

  • Step 2 Choose the first option, V-Chip TV Rating Limit, and using the arrow keys and the OK button on the remote, scroll through until the TV-MA rating appears. Press the right arrow button to move the highlight over to the "Status" field and toggle to "View." Press the OK button. This will set the age-based ratings to Mature.
  • Step 3 From the Parental Controls menu, select the second option, V-Chip Movie Ratings Limit and change the rating to TV_MA and the "Status" to "View."
  • Step 4 From the Parental Controls menu select the third option, V-Chip Unrated Program Block and select item one, which will be "View."
  • Step 5 Select the fourth option, which is "Channel Block." Highlight the Channel field and using the channel up and down buttons, go through and check they are all set to 'View." Any set to "Block" will need to be toggled back to View.
  • Step 6 Lock the controls to activate the changes using item six on the "Parental Controls" menu.

    SOURCE: forgot my lock code and need to reset it.

    Did you try unplugging wait a few minutes then plug in again. This should return everything to original factory settings.

    You will need to count the number of red led blinks on the power indicator, if it is at least 10 then replace the power supply it is faulty, In my years of servicing panasonic Plasma, power supply failure is about the most common failue in this class of television from this manufacture.

    There is a free section where you can post a question, but no guarantee you will get a response. You posted this in the free section. There are other levels you can post for money. There is the Premium section, and also the Chat section. Premiums usually get an answer...Chats almost aways get an answer.

    Hope this helps.

    Thanks for using Fixya.

    I tried what wah suggested and I am still not able to print. What do I do? Does this cost any additional money to ask this question?

    Since you are posting your question on the Free Thread page, you may receive responses immediately or may be delayed, but you can still post as many questions as you can until you are satisfied and your problem is fixed, there's no limit. If you are posting a new thread, you need to mention the description about your problem, otherwise FixYa experts can't assume the question or problem themselves. I would also suggest you to reply to the first solution so that he/she will assist you further with another better solution for you.

    If you wish to get immediate response, you may opt for Premium Assistance or Premium Chat or Premium Phone Support, but you'll be charged for the solution.
    Good luck

    Air filter keep popping on screen and shut off after 1 minute.

    I had the same problem with my Panasonic tv, just 3 days after a technician came out to fix "fuzzy spots" which were multi colored, but mostly green spots. I really thought that the technician was in some way responsible, but Panasonic insisted that there was no possible way he was. It was going to cost $240.00 for him to come out to clean the air filter, and both the technician and Panasonic insisted that I couldn't do it myself. I had decided to buy a new tv to cut my losses. My boyfriend talked me into trying to fix it, we are both sort of mechanically inclined, and it was going in the trash anyway.
    We took the back and top off the tv. It took some looking, but we finally found the filter, just over the projector. We removed the cover, it has to be done from the back of the tv, it is black and held on by 4 small screws, be careful not to drop them into the tv, we dropped one, but it shook out. We vacuumed the filter really well, and vacuumed around everywhere. We put the tv back together, not expecting it to work, but thinking at least we tried. It works great. It has only been a few days, but it seems like the problem has been solved.
    Good luck if you decide to try. I have decided not to put another penny into the tv.

    You will have no problem playing your non finalized discs on any of the Panasonic DMR range including the DMR EZ28 series. The DMR E55 can also easily be repaired if you can use a soldering iron and a little care. Please checkout my other postings for full repair details.

    Had the same problem.  Was quoted $800 to fix.  Searched the internet for 6 months and found this thread on



    Read through all the posts.  Very simple fix, but you have to have some mechanical inclinations or you can cause more problems than you started with.  I was up to 5 of the black lines, but decided to attempt the soldering these guys did and fixed it all for the cost of a soldering iron!  Even if you decide not to attempt it, it gives you somewhere to start to tell a technician.
