Question about Zenith B27A30ZC TV
Do you hear a whistle? if so, then the autotransformer is defective. Around $200 to fix. No whistle? could be bad power supply or bulb. This link will take you to a copy of the service manual

There can be any number of reasons why the TV will not come on. The main power board itself may not be any good, or any number of other electronic parts inside the TV. As there are some lethal amounts of current inside the TV, unless you are an experienced tv technician it would be a much safer idea to have your tv serviced by an authorized tech. Most modern TV's will not take long to diagnose and you can then decide whether to repair or replace your set.

No there is no reset button in zenith plasma tv.but in the tv there is a small fuse located on the main board of the tv.but if there is no light on the front panel of the tv then it is very much possible that safety fuse of the tv is blown out.the cost of fuse is near to $3.its made up of glass and looks like mini tube light.but if there is light on the panel but still tv is not coming ON then its not the fuse.because if fuse blows there will be no-power in the front panel of the tv.so the other option if there is a front panel light in the tv is.that in the tv there is a main board.on that main board there are several components.called capacitors and IC.any of that capacitors and IC are gone short so the circuit is not getting completed and the tv is not turning ON.The capacitors and IC which are blown will look bit bulged at its top or will look leaked at its top or will have burn marks on its side.the value of that particular component will be mentioned on its side.for getting the parts you can get it from ------ www.radioshack.com or from ------ www.shopjimmy.com ------- in some of the rare cases its seen that all the components on the main board looks proper and whole board goes faulty due to internal short circuit.so whole board needs replacement.but its very rare.it happens if any major short circuit has occurred before the problem occurred in the tv. ------------- if you are familiar with using soldering iron and multi meter you can get it checked manually and replace the faulty parts.other wise a local tv repair technician will be helpful. -------------- this will help.thank you for using fixya.please do rate the solution.thanks.keep updated.
