720p Trouble with PT-AE700U

Hello, I am having trouble getting the PT-AE700U to display a 720p image. Equipment used: Adcom GDV870 DVD Player: Adcom GTP870HD Preamplifier Processor: Monster Cables: HDMI Cables, connects from DVD player to preamplifier processor, then from HDMI out of processor to the PT-AE700U: M1000 HD-4 (4ft. length), M1000 HD-25 (25ft. length) Component Video Cable, connects from DVD player to preamplifier processor, processor can scale 480i --> 720p, 1080i/p: M1000 CV-4 (4ft. length) Before I go further, you should know that I also have this same exact setup running at 720p with no problems connecting to a Marantz VP12S3 projector, but for some reason, with the same settings I cannot get 720p from the Panasonic. The way I have the system wired, I can get a signal to the projector two different ways, I can use the HDMI output on the DVD player to pass through a scaled 720p signal through the preamplifier processor. There are settings in the Adcom that allow you to simply pass through the signal. The Adcom DVD player also has an auto setting, when selected we get a picture but only 480, not 720P. The second way I can send a signal to the projector is with the component video output of the DVD player, 480i, then allowing the preamplifier processors scaler to scale the 480i signal to 720P, again no picture unless set to the auto setting. So based on this, is there a setting in the Panasonic projector that would prevent the display of a 720P signal via HDMI input? Cinema Reality Mode is set to "ON", according to the manual, Cinema Reality is not 720P compatible. But the unit will not let us turn this setting off as it is greyed out, could this be causing our problems? Or is there another possibility? I am not an electronics novice and like I said, the exact settings in the DVD player and processor have worked flawlessly on the Marantz projector? Any help would certainly be appreciated. Thank you in advanced. Sincerely, Doug Gillis

SOURCE: Component Video inputs do not work

I started back in the day of tubes. A family would have one set and it would be a 19" black and white. There are different resolutions now. The components probably do work, but, they don't pass the 480i signal. The satelite converter's analog signal needs to be set to 480p and the DVD needs to be set to progressive if it does have that setting. If the DVD is not a progressive scan DVD, then, the only inputs that it will show on is the analog signal. Some of the dish converters have a switch on the face for changing the resolution. If yours doesn't then put it in an analog source and go to the menu and change it there. Then move it to the component input. Hope this helps.

SOURCE: HDMI Signal gone

The HDMI interface may have suffered a malfunction, this offten happens due to stray voltages on the ground plane. If you do not have electronics experience I would suggest taking the set to the shop and having it repaired

SOURCE: Panasonic PT-AE2000U All three HDMI Ports stoped

WOW. I just experienced the same thing. None of my HDMI ports are working, though component is fine. I've had my unit since November 2007 and had no problems until this. I think the HDMI board has gone bad and will require replacing.

It sounds that a software update is necessary. Contact the service centre for Panasonic, to get the latest software to this model Plasma tv.

may be a heat problem: check the psu unit for components getting too hot...use a laser thermometer and keep you fingers away from the psu ! other possible problem may be a bad capacitor or the thermal protection before the psu..but this would be a very uncommon problem.

PT-AE700U No Power

Hi ErnieN008

If there is no LED's flashing or even lighting up for that matter , then it could just be the fuse on the Poersupplyboard that has gone.

You can replace this fuse by opening up the top cover and looking for the board with the AC inlet on it.

If the problem however still exists , you will have to replace the powersupply.
