Zenith Z20LCD1 My in-laws inherited this TV from a relative who died, and have no manual. We can't figure out how to autoprogram--it doesn't appear when you run through menu options. Without autoprogramming we don't seem to get all channels on cable. Also, it seems that using remote to go to a double digit channel, such as 45, you can't punch in 4 then 5, you have to use 100 button, then 4 then 5. Is that right?

There is no such key fix. Just try an other code to set-up with your remote control. If you wish to get more; check the site linked here. It has set-up code list & set-up procedure to many popular brand remote controls. See it in "Mosaic" view. It will make surf easier.

Try this link to zenith it should take you directly to the Product support page. Click on Product Support in the menu bar then click on the owner's manuals link on the left side of the page. You'll want to select TV as the product group, then PDP TV as the product, ENGLISH for the language, and finally type in the model number.

I connected a vga cable into my unit and my netbook but it's also saying "no suport".
help, I'll like to use my unit with my z20lcd1 tv/monitor unit.

To turn off the 100 button you need the original remote.

this is from the manual:

PC S ettup ((Z151L5CLC1RD1
onlly))
Connections
1. Set the monitor output resolution on the PC before connecting to the TV.
2. Connect the TV to the PC with the PC cable.
3. Connect the PC audio output to the TV's PC S OUND input.
Viewing Setup
1. Turn on the PC.
2. Use the PC b utton on the remote control to select PC .

it appears only the 15" model may be used as pc monitor

This TV's VGA port does not appear to be used for monitor purposes. It says "for service" in the manual, rather than being described as a PC port. My guess is that this input is used for some other type of display not available to the customer for regular use; only during maintenance when taken in for repairing, or something similar...whatever the "for service" means. But rest assured, only a VGA to component converter will give you that VGA PC screen.

same problem, after hitting power button hit channel up or down and it comes on
