I just recently obtained a used 1997 Zenith Inteq model # IQZ36Z46D . I hear the sound just fine on the unit but have no picture or snow at all. The integral yoke-picture tube assembly is permanately bonded. I am not sure what to look for with such a problem and hope I can get some input.I am really not too electronic saavy.

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience.

Zenith's service site lists a manual for a model IQB36B42W manual, and it will probably be close enough. But the site is pretty lousy. You can't just download the manual; you have to view it on the site. The manual is in djvu (deja vu) format, and Internet Explorer is required so an activex control can install a viewer your computer. It doesn't work if you try using Firefox like I do, and I don't know if Google Chrome will work either. But if you want to jump through all the hoops you can see if the manual helps.
You can also try calling LG Electronics customer service at (800) 243-0000. They own the Zenith brand now and maybe they can help get you a copy of the right manual.
Hello to all, I have a tv zenith model C27V36, and it has a problem I connect it in the series and it does not turn on and I connect it to the network(net) and immediately burns (damages) the horizontal exit that is a trasistor C5905 and it burns (damages) both resistances of the protection,I changed the trasistor C5905 for a trasistor C3997 that is 20 amps and nonetheless it burns it,there are no signs of short circuits. Could the problem be the high horizontal ocsilacion?? But since turning it on it burns(damages) the horizontal exit I do not have way of checking it, because it is automatically damaged . can someone please tell me what to do in this case??? Or where I can find an electronic diagram or a sketch??? Or can someone who has worked on this TV before h help me out?? It is a zenith model C27V36 of 27 ".. thank you for you help.
