I've had a Zenith TV (Model SE2715H) which has worked great for the last 10
years. I moved it to another part of the room for the first time, and now it doesn't work. It has no picture or sound (It is plugged in). What could I have shaken loose that would cause this? If I leave it plugged in, after about 30 minutes to an hour it will make a knocking noise. Thanks, Mike

Good Afternoon, Mike F:
I need you to elaborate on the condition of the television set when you turn it on. You say there is no picture. Is the screen black or is it lit up (solid raster). You say there is no sound. Is the sound dead quiet or is anything coming from the speakers?
Several conditions can occur that will give you a "no sound/no picture" condition and I need the information to evaluate the failure.
You say it knocks after a while? Does this sound come from the speakers or is it from within the electronics? I've been through snapping, cracking, buzzing, and various sounds but am not familiar with a knocking sound. Perhaps an evil spirit? :eek:

Smokey, it is totally dead in the water, no picture or light and no sound. A slight humming or current noise comming from the back of the set.
Maybe the knocking noise was my son knocking on the wall because I can't get the sound to repeat.

Good Morning, Mike:
Thank goodness we cleared up the knocking thing. We don't need any haunted TV's on this site.
It sounds like the low voltage power supply has crashed. Since the set is essentially dead, this would be the first place to look.
If you are adept at these things, you can get a schematic and parts at (the only place in the USA with Zenith diagrams):
The company that stocks it is
Union Electronics, 311 E. Corning Road, in
Beecher, IL 60401.
You can order it direct off the web using your credit card at http://www.unionel.com
You email them at uebweb@unionel.com and send it to the attention of Carol.
If the picture was acceptable when this all happened, then it is worth a look to see if it can be resurrected. The repairs to a low voltage power supply are usually not expensive (if you do it yourself). Tech labor for TV repairs at a shop (if you can find one) are off the scale.
Good luck on the repairs ;)

Smokey, this is the response I got back from Carol? Can you answer her question on the module and any other alternatives for the service manual?
Hello,
The service manual for model #SE2715H is no longer available. We do not
have stock either. I can not identify the 'low voltage power supply' Is
this an individual component on a module, or an entire module? Do you have
the part number off of the module? (It should start with 9-)
Regards,
Carol

Hi, Mike F:
Typical Zenith, I guess. What I would do is email or call the Zenith Factory. You can pick them up off the Internet.
What I have found, though, with Zenith is that once it hits the market, the support disappears. In the old days, the Zenith motto was "The Quality Goes In Before the Name Goes On!" Anymore, the reverse is true. The Name goes on before the quality goes in.
Second choice is to check the Internet for Sams Photofacts. Some Zenith receivers were actually documented by Sams and I highly recommend them.
Check out the following URL. You send them (via the web) the model of your television set and they send you a complete set of diagrams: http://www.samswebsite.com/about.html
