I can´t sintonice more chanels than 17. How

Re scan your channels. You might need to adjust your antenna as well.

Try unplugging power to the unit for at least 10 minutes or more then plug it back in.. it should try to automatically setup everything. If not manually set the time first then make sure if it has a option to switch from ANT / CABLE that it's set to cable if you have it connected to a cable system. Now try auto scan/store channels.

that's a big problem.... please see find the remote so that your problem will be solution

Google this manual download from panasonic.com link.You need adobe pdf reader or sumatrapdf to open the manual.

Try going into menu and auto program channels in. Try this first.

The only way would be a scart lead from the cable box into av2 on the vcr

You have to tune all the chanels first, then only chanel will change.

try hooking the system up so that it uses a different channel when in use.

First make sure how many chanels the TV itself has.. Some TV's (usually the smaller 14" old CRT's) dont hold that many chanels..
