Maxent 42 inch TV Keys locked and Remote will not work

SOURCE: how do you hook the up

Use the instructions that came with the device for full details. Their site is down, so you can't get a manual online at this time.
Usually, all you need is video input (a cable connection) and power.
If you have a straight cable line (no box), coax cable connection is will work if supported.
If you have a box, the better cables support the RGB and audio split, and will give you a better quality picture.
Be sure all are secure connected, and that if you use the RGB/Audio split connection, be sure each matches the color coding on the connector.

Trying to program a universal remote can sometimes be a frustrating process. Successful programming of a universal remote depends on whether the universal remote manufacturer included our company’s information in the remote when it was assembled.

Then a cable company (ie., Comcast) or satellite provider (ie., Dish Network) orders their decoder box and universal remote control from a manufacturer (ie., Scientific Atlanta, Motorola, etc.), the decoder box manufacturer provides a list of all the possible remote controls this universal can duplicate. From that list the cable company or satellite selects which manufacture’s products to include on their new universal remote. Once those manufacturers names have been decided, they are placed on the universal remote and a numeric code is assigned. If they choose not to include our company on the universal remote, the universal remote may not access the Maxent screen.

If you cannot locate Maxent on the list provided to you by the universal remote provider, please try the following:

Through contact with various cable and satellite content providers we have developed a list of the most common numeric codes that are used with universal remotes.

Content Provider/Most commonly used code

Comcast: 1755
Comcast (ML-3251HLT Model): 0054
Insight: 1755
Direct TV: 11755
Dish Network: 742
Cable Vision: 165
Adelphia: 0156, 1755
Universal: 0762
One4All: 0036
Time Warner: 0230


We have identified other manufacturers of display products that have similar remote control information to ours. Depending on the universal remote you are using these manufacturers may work. Please use the documentation that accompanied your universal remote, and look up the following companies. Input the numeric code associate with that company.

Gateway
Sampo
Viewsonic
Magnavox
Phillips
Marantz
Pilot

If the universal remote you are trying to program contains a Code Search (the remote will scan through all the codes contained within the universal remote) function, we recommend that you try that procedure. It is possible that there may be another manufacturer code that may work with our monitor.

You may also want to try a Learning Remote from another manufacturer. This type of remote control can absorb or record the information coming directly out of the Maxent remote control. The learning remote then duplicates that information and acts like the Maxent Remote control. This type of remote can also record the signal coming from your other universal remotes in the same manner. In which case you can use this learning remote for your entire audio video system
