How do you open the menu to do an auto channel scan on a zenith H2521Y3 without a master remote. It is an old ''hotel tv'' that I ''thought'' I got a good deal on.

These hotel sets have a pretty complicated setup menu. You will have to get a "master remote". The hotel has the "master remote". They really should not be selling these sets without setting them up for a non comercial application. Try www.encompassparts.com and see if they list a Master remote or a service remote. I would check myself but you didn't post a model number. You have got to have the model # for encompass.

1. Did you try to call LG/Zenith customer support and see if they can help you? If not find your nearest LG/Zenith service center (not Best Buy) preferably a small service shop to see if they have a service remote to unlock it

eeprom need replace.or reprogramme it.

USE ZENITH REMOTE HOLD DOWN MENU BUTTON UNTIL THE OSD DISSAPEARS THEN HIT 9876 ENTER CHANGE P/L SETTING IN FACT. MENU

In order to get all the channels u have to have the original remote or a universal remote that has a menu button, an enter button, and directional pad (the directional pad cannot control the volume and channels it must be for navigating). push and hold the menu button, the menu will appear then disappear, once it disappears release the button and enter 9876 then press enter. a different menu will appear and it will b three black lines, one at the top of the screen, one in the middle and one at bottom. the middle line has 3 sections the first part is the item number the second part is the description and the last part is the on/off switch using either a 0 or 1. push down on the directional pad until u get to the 00 factory settings 0 and change the 0 to a 1 with the right button on the directional pad. then scroll up to 20 channel lock 0 (i think its 20, it may be like 22 but it is in the twenties for sure) and change the 0 to a 1. then go back down to the 00 factory settings and change the 1 back to 0 then turn the tv off. when u turn the tv back on it will either automatically ask u to auto tune or u will have to go to auto program to program the channels. there are like 80 different menu items, be sure not to mess with any other ones unless u know what ur doing, u could cause ur tv not to function properly or even be able to turn on.

this problem frustrated me greatly and im very happy to help whoever i can with the solution

You have a hotel/motel model that cannot be programmed or any of the settings changed without a special Master remote. Sorry, doubt that you can buy one from the store, they are not sold to the public. Contact the hotel where you bought the set and try to get the model number for the remote from them. This is a different number than the model number of your tv.

if you can get to menu to unlock the channels type in 0000 or 1234 or 9999 or 0001 orif this doesnt work you could take back off tv and remove the little battery that looks like a coin out. becareful, this is high voltage in there.........

Your best solution is to get rid of that crappy TV! Having an old tube Tv really makes the rooms look bad.

If you have a remote that can access menu and your remote has number buttons and an enter key, you can follow this instructions to go to installer menu. Note that the installer menu is slightly different for each model, eg. some options are not available.

I was able to go to installer menu using two universal remotes. The remotes that I used were Dish Network 3.0IR and RCA RCU300WBL. Both remotes programmed for Zenith H2531DT TV. The reason why I had to use two remotes is that Dish Network remote was only able to access menu. It did not have ENTER key but RCA remote had ENTER key but I wasn't able to go to menu with that.

To go to installer menu (different from regular menu):

- Hold MENU for 8 seconds.
- Press 9, 8, 7, 6 and ENTER in the sequence.
You should be in the installer menu now. There should be a line that looks something like this:
03 VERT POS 13

Use SELECT button to scroll through each option, and ADJ button to adjust the values for each option. For example, to enable the front panel buttons on your tv, set KEY DEFEAT to 0. Other options that you might want to check:

CHAN LOCK which locks your TV to a single channel and wont let you change (set 0 to turn off)
START CH/VOL will set your tv to a specified channel when you turn on tv. (set 255 to disable)


You will have to look in the menu for some of the options because they are different for different TV series. A good place to find manual is on www.zenith.com or http://safemanuals.com/

I work in an old hotel and it took me few hours to figure out how to disable start channel lock. It drove me nuts. I hope someone finds this useful.

The "H" model Zenith TVs are hotel/motel sets designed that
a roomer cannot access the menu feature. Your best bet would
be to purchase a name brand universal remote which has the
menu button feature or order an original Zenith master remote
which would not require programming. Once you have a workable
remote which will allow you to access the on-screen menus you
should be able to program the channels.
Hope this helps,
