Menu on 2 used Zenith's ''Presentation Series won't work

I have recenly aquired 2 Presentation 27" zenith's I already have another one identical to the 2. The first works great the next two have the exact same problem, 1 was manuf. in 99, the other 97. They have preset channels that work fine but I have no access to the menu of either one, either on the front panel or by remote. All I get is menu> and can't do anthing else. Is there a reset, or is something seriously wrong with them. It seems odd that both have the exact same problem, they did both come from the same school so I didn't know if it was a setting they put on there. With the remote or front pannel I can adjust volume and channel up or down, but cannot enter a channel # and go to it. On the identical unit that does function, when I change channels there is a red box on the upper right around the # on the two other units sometimes they try to do this but immediately go to a small yellow # on the left. Other than this issue they have good picture and sound. I sure appriciate your insight on this. Jim

If you have a problem with the convergence, believe me, going into the service menu and trying to correct it will only give you large headaches, DO NOT USE THR SERVICE MENU UNLESS YOU ARE A TRAINED TECH!!!! Doing so can result in a complete and total failure of this TV set. I service menu is not for any major changes in any adjustment. It is not the cure all. If your convergence all of a suddenly shifted, it is not a service menu issue. Your problem is the convergence amp IC's. Good Luck

SOURCE: Zenith 44" LCD TV

The yellow spot is due to the BLUE LCD and/or lens assy cracked, reason, to much HEAT! The blue is the darkest color and hold the most heat, so it goes first, always! In some cases it’s only the lens, however most of the time LCD is damage to. Parts are available, however install and alignment is timely. Quick fix is the complete light engine, which for model# E44W46LCD is part# 3141VSN916C, which customer cost is $1,449.27, wholesale for about $1,065.21. Rebuilt, if you can find it around 850.00 to 950.00. However the rebuilt does not always look as good as factory. My advice, TRASH set. This part will fail again in about 3 to 4 years, unless you watch a lot of white video. Remember, on a black or dark picture, all three LCD are blocking 100% of the light, causing extreme heat within the light engine. It’s a bad design.

SOURCE: Problems after convergance IC fix

try not to mix areas in the tv chasing several problems.

  1. Lets get back: i hope the tv was doing fine before to start digging into it ( was it?) Was the tv complete tested before to make sure the buttons were working all and the audio was there. I mean each part of your tv has different solutions:
Think you have an animal with several heads now:
  • the buttons in the panel (some working is good! some others can be replace and there it go all panel works)
  • audio mute (maybe no signal and automatic mute is there. or maybe really audio is damaged. Leave it at the end is another area.
  • Touch focus is the the program controlling convergence digitally talking. If the tv is not yet fix with the amplifiers then the problem still landed in another area not in the digital control.
Finally Start over! Get into de convergence and get your three tubes at least close to convergence (forget auto focus now) three screens together or almost but three rectangules with white noise. No having GUI you mean OSD (i gess) (on screen display) channels appearing when you push that button or audio level line or menu letters (several buttons have to be touch to make sure of there is not OSD.

if the tv has not white noise the screens are without convergence. you are digging in a set with maybe 5 problems the three you told me plus the other posibilities im gessing and i hope you don't have. So slow down with the repair and try step by step. bye now.

SOURCE: Problem with remotes for our zenith e44w46lcd tv

It could be that the main board or the remote reciever is bad on the TV. The best thing to do at this point is to have a technician verify which one is causing the issue. Otheriwise it would be an expensive gamble to replace both boards. Please take a moment to rate my answer. Thanks..

Zenith factory reset


Hi Rebecca,

Specific reset instructions will vary depending on the model of your Zenith television. For many Zenith TVs you can reset to manufacturer defaults by pressing 'Menu' then press '9, 8, 7, 6, Enter.' If this doesn't work for your set, try a hard reset: unplug your television and leave it unplugged for at least 4 hours.

You can also try this:
Instructions
    • 1 Press the "Menu" button on your remote control. Use the up and down arrow buttons to highlight the video option. Press the arrow that points to the right to select the video option.
    • 2 Use the up and down arrow to highlight the video reset option. Push the right arrow button on the remote control to select video reset.
    • 3 Press the right arrow button on the remote control to return the video to original values.

Zenith Presentation Capacitor


Hello again! Sorry, I was not more exact... capacitors are not all alike...too long to go into...100uf 50volt Electrolytic Capacitors are what you need.
I always use the phone to order what I need and when you tell the parts person you need a 100uf 50 volt cap it's already understood that you want Electrolytic capacitors. It' s pretty rare to have to order the other types of capacitors as they are extremely long lived and are not in "high stress" circuits anyway.
Can you please tell me the model # of these sets. I will obtain (if I don't already have it) the service manual and make sure I am telling you 100% correctly what your problem is. Zenith tv's have always been notorius for this problem all through the '80s \ '90s \ early 2000s though. That's why I am telling you it is this same capacitor in all these sets
It makes me happy to help a school too! I am the single Dad of two elementary school age girls.
Is your school system in the USA? Just curious... Hope you have nice day!

Can not find code to program my tv and remote control I have a zenith television and a zenith universal remote


One website (Thompsontv.com/zcodes.html), says that the setup code for a Zenith TV, using a Zenith universal remote, is one of the following numbers: 101, 142, 149, 177, 175.
If these numbers do not work, visit the Zenith website (Zenith.com) for contact info.
