You will need a Zenith remote with a menu button
There should be a "hidden" menu. Before you access it, I want to warn you, do NOT change any values of anything you don't understand what it is or does. You can PERMANENTLY DAMAGE YOUR TV. Also, write down the original values of anything you change before changing it!!!!!
If you still want to proceed(at your own risk), here ya go.
1. Press and hold the menu button until
the menu comes up on screen and then
times out (5 - 10 seconds)
2. Immediately press 9, 8, 7, 6, Enter.
3. The set should now be in the service menu
mode. To access most of the features
selection 00 needs to be toggled from 0 to 1
4. After your adjustments 00 needs to be
toggled from 1 to 0
5.Feature 16 unlocks the auto-program (change to 0)

Picture is dark

sitnlisten - yes it does appear your pix tube is getting weak,but we may be able to turn up the flyback alittle to brighten up the picture.If you take the back off you will see the flyback-large black unit with a wire going to the round rubber cap on the back of the pix tube.Look at the flyback there are usually 2 adjusters one marked focus the other screen,just turn up the screen a little bit at a time.If you turn this up too much you will wind up with retrace lines on the screen.You may also want to check the pcboard ass'y for a sub bright adjust,and same thing small adjustments.If this don't help your pix tube may be too far gone.I hope this helps. cooltek Feb.1/08

Zenith Z27X22D Service Menu Codes needed

significant vertical overscan. It is such that it's impossible to read crawls and such at the bottom of the screen. I think this problem is a tv problem. it is due to vertical section. please change electrolytic capacitor in vertical output section. it will be ok. it is common problem can be fixed at home & very simple.

Picture is dark

Does not seem like a bad tube alone. Could also be that the Video output Transistors Supply Filter capacitor having dried out. It is a 100mfd 160V capacitor, which on replacement will improve the brightness of the immage. And yes, you could also try increasing the heater voltage (Filament Voltage)of the Pictuire tube, this will definitely increase brightness, but will reduce the life of the Picture tube. You gotta think - 10 year old TV, should I repair or exchange and get a new one???

Cannot access menu

The tv has lost the menu,in order for the menu to come up in the screen it needs horizontal and vertical sync,the syncs come from the secondary of the flyback and from the vertical Ic.Is rare but We have seen it happen,sometimes you also have an Ic called character generator and it could be bad.You will need the assitance of a servicer for this problem because there are voltages to measure and signal to trace.
