Re: tv will not power up
Sounds like a fuse or fuseable resistor may be open due to a short in the high voltage circuits. I would first check the Horizontal output transistor Q7460 and if that was shorted, I would replace C2455 (47uf/50v) as well to prevent a reoccurance of the problem. Of course with the prices of 27" TV's falling, it may be un-economical to repair.

Your problem could be any one of the boards in the set. When a flat screen attemps to turn on, but finds an internal problem, it defaults by clicking off to keep the remaining circuits and boards from buring up. You'le have to take the tv to a shop.

if your could hear a slight ticking (tick-tick tick) or whining then some electronic component might have been damaged (shorted). if you have no experience repairing electronic equipments then i suggest you to send your TV to a service station!
hello .this does sound like bad solder joints .all printed circuit boards do this after a while due to heating and cooling .is not advisable to try to repair yourself .possible electric shock and spiking .will do a lot of damage .take to a shop to have repaired
we cannot get a picture or sound on several channels. Otherwise the TV works fine. Any solutions?
as you get p&s on several channels so your ser is ok the problem
1 loose contact near tuner or it is defective.
2 tuner signal line .
Sounds like tyo me that the picture tube is getting soft on ya!!. Its a common factor that occours with all tvs but mostly with zenith. A service tech might be able for a small fee rejuvinate the picture tube but theres never a warrantee with this type repair. Its not something a user should attemp to do as theres hi voltage inside this set even on the tube socket after its ubplugged for awhile. Seek the advise of a repair pro to see how bad the tube is. Good Luck
