Why wont my tv turn on


Hello
Do any indicator LED at it front panel lights up? If lights up, and the TV won't turn ON, the fault is with its internal circuit board. If not, the fault is with its power regulator board.
This is the picture to the power board to your tV.2_7_2012_4_24_00_pm.jpg

No sound from zenith dvt412 stuck in bypass mode..how to override?


this is a protection circuit.
When bypass mode then it means that something in the power supply module has failed and the unit then goes into protection mode to protect the board components.
Your surround sound need service from a qualified tech. No other remedy.

Tv will not turn on after sudden power outage


you most likely blew a fuse the only "reset" is to unplug the t.v. and leave it unplugged for a few mins, then make sure that you hold down the power button to drain the power out of the t.v.then turn it back on.... only other reset sequence is for removing the parental code

Zenith rear projection 60 in a60m91w1


The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.

How do i hook this to tv or digital cable to get surround sound?


Sorry to say, Circuit City is right. These cheap home theatre in a box solutions are very very shady. They put the DVD player, preamp, and reciever all in one little box. Not very handy to adding options or plugs but very very cheap to produce. Ever notice why large home treaters have about 5 big black boxes and a DVD player? This little box is trying to be all of them. If this was a reciever combo(as zenith wants you to think) then you could do EVERYTHING you were thinking would just make sense. Unfortunately, you trusted Zenith instead of Circuit City(gah i hate saying that). At any rate, if you still have receipt, return it!!!! I will help you pick a system to suite your needs. I do all the things you want on a system i got for 500 bucks.
