LGRH177 I have had this over a year with no problems...now will not output a picture ('no signal' on tv) and keeps displaying 'please wait' message over and over. Can anyone tell me a possible fix or way to reset the player...THANKS

It sounds like you have taken the steps to isolate the problem to the TV. it seems to be a bad tuner on the Main board. The no signal displayed indicates the TV is otherwise okay. If you have a DVD player or other source you can connect, and you get a picture, then your TV has a bad tuner for sure.

Is your DVD Player's model WDP1210 or WDP3397B.

If you are using one of these model I will strongly recommend to use AV output to a TV instead of using its LCD screen. If you get full picture at TV, You will isolate the matter that LCD module has problem. If so you can check with a local repair center. If you have any help regarding TV connection via external AV cable please post a follow up message

Hope it will help
Happy New Year

Call for warrenty serviced,u still have warrenty inforced until a year.Ur tv have intermittently signal shutdown before it come throught the Tuner board not,carrying to the LCD Screen to produced a picture.

When using the Component outputs on the player, make sure they are enabled in the player menu system (or sometimes there is a rear panel switch and sometimes both), as most players default the Component outputs to off. Even when the Component outputs are off, you will often get a color-distorted signal out as many players share circuitry between the various outputs.

Try all of your HDMI inputs, one may be rated at the correct voltage to be able to display the video. The offical part that Panasonic was giving for this was PDPHDMIKIT, its basically a HDMI extender that regulates the voltage. The part is still available online, try partstore.com or andrews-electronics.

Check your resolution settings on you playstation 3 menu's. If you are using an HDMI cable, there is a chance that your ps3 could be trying to output at 1080i or 1080p. The unit you have only goes up to 720p and if you set it any higher than that, you run the risk of having picture issues, or not getting a picture at all. Good luck to you

If the screen resolution on your laptop is to high or not supported by the TV, that is the usual error message.  I'm not sure what video output you are using but if it's the common S-video output, high resolutions will not be supported through it so maybe try a lower resolution and work your way up until you get the message again.  Then you will know the threshold.

is there any picture at all ? if no signal message regardless of any signal input , ur ad board need to be change.

Un plug the power to the Plasma Screen and also to the Media Receiver for ten minutes. Disconnect the off the air antennas both A and B. After ten minutes plug in the plasma screen then the media receiver and turn on wi the remote control. You should now be back in operation. I was.
Also It may not be a bad digital tuner. The TV Guide feature is active even when the zip code is set to all 0s so if you have an over the air antenna attached the TV will look for the TV Guide info and if it can not find it because of a weak signal or the chanel it is tuned to does not carry that information the TV thinks that tuner does not work which triggers the 12 flashes. Also on power up the gray box with the waring message "Plasma Display Starting Up, Please Wait" appears and the screen is blank.

• The resolutions available for HDMI output depend on the connected TV or projector. For
details, see the user’s manual of your TV or projector.
• When the resolution is changed during playback, it may take a few seconds for a normal
image to appear.
• If you set the HDMI output resolution 720p or 1080i, HDMI output provides better picture
quality.
• If 720P or 1080i is selected, C-VIDEO, S-VIDEO and component video will not ouput video
signal. Press and hold the SUBWOOFER button on the front panel to reset the HDMI
Resolution setting.
