Re: will not turn on

It's related to some internal board failures. It could be the power supply board, or DG board, or even H board. If your tv is still covered by warranty, just drop it to warranty depot shop to repair.

Panasonc th-42px500u picture is too big, but zoom adjust is greyed out. how do I fix it?

The problem is in the TV settings not the cable box. There should be a button on the remote to cycle through the settings. Not sure which button it is but I've dealt with it before.

Try disconnecting all HDMI cables and plugging the TV into a new wall outlet. If the issue is resolved, it may have been caused by a small power surge from either your wall outlet or one of your source devices.

Aspect Ratio Memory?

Problem could be the fact that you are connecting with composite cables. You should never connect an HD receiver with an analog cable like composite. It does not give a HD picture. You want to hook this up with HDMI. This might also help your problem because of the fact the native aspect ration of composite is 4:3.

Get HD Signals but it Says Channels not available

you might have to look for "hidden" hd channels.

most cable companies are broadcasting the local stations unencrypted, so you should be able to receive them and sometimes a few other "basic" hd channels like discovery or tnt.

try googling your cable system, city and hd channels to see if someone has posted a list of channels (eg, 88-1 or 102-1)
