    I have the same problem. I managed to get rid of the blue screen by going to Menu > Options > Blue Screen > Off. Now I can actually see all the channels, although the "No Signal" bubble appears over the top of the picture after a second or so. However, I don't have any sound. Also, the tuning doesn't seem to 'hold' - ie if I turn the TV off and back on again, the picture on all channels is jumpy, as if the TV was not correctly tuned. Auto programme fixes this, but then the TV returns to its silent "No Signal" state.

I was having same problem, and think I got lucky and found fix.

Try unplugging the TV and waiting 30 seconds, then plug back in.

You will likely get blue screen with "No Signal".

Go to Menu, then scroll down to "Setup". Select "Factory Reset" then hit "Yes."

This did it for me. Wish you all luck.

My Polaroid 32" HDTV just recently acted up: it has loss it's HD channels (ie 2.1, 2.2, etc) all of a sudden. The TV is set to "Air" as supposed to "Cable" setting even though it is connected to cable that only has two cable channel. It was fine before and had set the TV several time to rescan for channels and it was perfectly fine. I tried several times to scan and even resetted to its several manufacture setting and had no luck what so ever. I know for the fact that if when it scans for channels it only receives those channels that are most clear and strong, while it leaves out those that may have weak signals. I never had problems recovering those HD channels but now I have all analogs insteads. It's driving me insane because I hate the fact that these locals channels have HD and I only get their standard analog signals. I know that this is not the best brand of TV out there and it worked. My TV is feeding off cable with limited cable broadcast and should still work even though it is set on "Air" as supposed to cable.

Please let me know if anyone of you have encountered the same problem(s), and if you solve the mystery. Would some please tell me what does "PIP" on the remote means and what and how to use it. Thanks in advance.

PS I woudn't be able to return this TV back, the store that I bought this just filed Chapter 11. :(

So, I couldn't get the tuner to work (tried everything). Eventually I realised the cheapest solution would be to buy a digital set top box, and use this as the tuner instead of relying on the one built-in to the TV. Works fine.
But yes, I won't be buying another Panasonic in a hurry.

Don't ever buy a Polaroid television again, manually reset factory settings via Menu button. You must do this each time you turn on the television when it was off.

Fix blue screen av27870

Hi. Switch off (mains switch) the VCR. Then see if you can change channels with your TV remote. Blue screen mostly means that no channel has been programmed. If there is , you should at least have the sound. So, if you have sound, there is an internal problem in the TV. If no sound appears, try to get into setup mode (button Menu)
and programm your channels. I suppose there is signal on your normal areal connection. Check this out with another TV set, or use the tuner from you VRC. I know there are a lot of possibilities, but you can sort this out, step by step. Good luck.

If it shows "No Signal" it means it. It do not get any signal to display. Check all the settings. Refer its user manual for details. First, try to tune it to on-air program, by do an auto-tune function, after connecting it to an external antenna. Refer its user manual for more details. If it do receive all the channels transmitted, means, the set is OK, and the fault will be with the input selection, you've done. OK?

Program Blocked errors

I was having the same problem with the constant blue screen appearing with different error codes. Here is how I fixed the problem on my Elements 19": I did a channel search. I found there were 68 analog channels and 274 digital channels. On a hunch, I went into Skip Channels and checked off all the digital channels since I have basic cable. Although the tv is HD and did pick up the basic HD channels, I choose to skip those two since I do not have a cable box on that tv and only the basic channels were in HD (about 8). I watched my tv for two hours and blue screen appeared once every 30 minutes, but the next day it did not appear at all.

I concluded that those error messages are because those channels are blocked and we have not checked them off to be skipped. When checking the Skip Channels, as you highlight each channel it will either come in or it will not. You will find the "Blocked Program" errors are coming from channels that do not come in and you will need to skip those channels.

I hope you can understand how I solved my blue screen problem on my Elements tv. Good luck!

Digital channels have stopped working, only blue screen!

Try resetting the TV:

  1. Switch on TV and switch to any analogue channel.
  2. On the TV: Press and hold the MENU button.
  3. Menu screen will appear on the display.
  4. Do not release the MENU until the menu screen disappears.
  5. TV will go blank for about 60 seconds and then display initial set up screen.
  6. Follow the on-screen prompts to re-tune the TV.
If this does not work then the problem is likely to be a loose ribbon cable or main small signals board inside the TV.

Suddenly no sound & no picture overnight: is my TV dead?

If you have static siugnal, sure TV is not dead.

Check the aerial cable, ensure it is well plugged in and getting signal.

If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.

Test the TV on standalone , connecting it to an external antenna.
Tune again the channels, and save the preset.
If still no signal then the antenna socket on the TV may be defective.

Try using the TV with a DVD.

If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.

Call the phone number listed on tv user manual to get support, and eventually repair it.

"No Signal" floating notice on Blue Screen - No other picture

If all connections and the tuner have the same issue, you either have a power supply issue or a bad digital board.
