Power supply section schematics to many popular brand TVs are given.
IF you have the serial number you should find the model number.
The model number is essential for getting more information. One trick is to put 'old Zenith TV images' in Google. You will get lots of pictures. Find the pictures of yours and some will have the model number stated. From there you can do search on that model number. You should be able to locate manuals, etc.
It is possible to get your TV1 remote to work TV2, but it would have to be a model 6.0/6.3/6.4. If it is not one of those models you would need to have a remote ordered and sent out; then it would work. If your remote is one of the above models; I have included the steps to get that done.
Changing Remote from UHF-to-IR and IR-to-UHF:
1.) Verify correct model of remote and it is IR/UHF compatible. Remove tab from bottom of remote. For TV1: Green Tab with Green 1 in it. For TV2: Blue tab with 2 and black UHF in it.
2.) Push correct tab into remote, and go to your main TV.
3.) Access System Information either with a remote, Sys Info button on front of receiver, or powering it off and pressing the up arrow.
4.) Press and hold the gray SAT button until all buttons on top light up. Release and while the light is blinking enter a number between 1-15 and press Pound(#)
5.) Press Record 3 times and check to see if the address changed to the number you chose. Verify remote works.

Try the recommendations in a document posted on the FCC site (http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-291403A1.doc)
Also be aware the several stations have had problems with the transition. Some changed frequencies on which they were transmitting and encountered area coverage issues that didn't meet their expectations. They have been working with the FCC to remedy the problems and many stations have temporarily increased output power to compensate for the issues. Some of these stations may be difficult to receive and you may need to get larger antenna. If you are still having problems call the FCC DTV transition hotline at 1-888-CALLFCC (1-888-225-5322) or the TV station for advice.
