If your NAD amplifier is in protect mode with no speakers connected, it will be necessary to open it up and check for internal component failure.

How can I get Dynex TV out of "protection mode"?


the protected mode kicks in when there is a safety issue with the receiver. This usually comes from an overload to the system via a short in the system or perhaps a surge in power. Your receiver shuts down, and you'll need to shut the entire system down to fix it.
In some older homes, some of the wiring doesn't deliver the "cleanest" power, delivering minor power surges to the items you plug directly into the wall. If your receiver is plugged directly into the wall, purchase a surge protector to stop this

How do i stop lightning from getting in my hdmi lines and shocking my tv? 5 tvs went down in one storm


I would recommend getting a surge protector and using that to protect your televisions. This usually will stop something the lightning from killing your tv's.. I have a surge protector and can still use my tv, computer, anything I have plugged in during a storm.

Our electricity went out for a few minutes, and since then the TV will not turn on. The green light is flashing. We tried resetting it by pushing a pen point into the reset hole, but it does nothing. ...


Your power outage may have been caused by a nearby lightning strike, or any number of
1000 different reasons that cause power surges, brown-outs, voltage spikes, inductive loading,
and/or utility pole breaker trips and resets (this accounts for your power loss (a pole breaker trip),
followed by restoration of power (the pole breaker automatically reset) - even plain old high electrical demand causing an overload due to air conditioning demands caused by hot weather.
When the pole breaker reset, your TV caught a power surge.
Whenever a power outage occurs, quickly power off (or better, unplug) any/all computers, TVs,
etc. that are not protected by surge-protection.
As an electrician, when someone loses an item of electronics concommitant to an electrical
anomaly, its almost
always traceable to a nearby lightning strike (or the power company provided equivalent), accompanied by inadequate surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360/Nintendo Wii.
Surge protection can
be provided by the consumer at the power strip (a good one with builtin MOV protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house surge protection where a whole-house MOV-based (metal oxide varistor) surge protector, or per-circuit protection can be installed with
a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed and/or fuse blown), other than renters insurance or homeowners insurance.

Your only real hope for an economical fix is to look for a blown fuse, and replace it.

If desperate to attempt a fix on your own, you could try replacing the entire TV power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

I have an av316 NAD, surround sound Amp. Just got back from repair. The wires to the speaker may have been reversed when hooking, the amp went into protection mode, can I fix this problem. It wont come out...


Having the speaker wires hooked up backwords will not cause protect mode. If the wires were crossed (in other words shorted), that would. Disconnect all speaker wires, if the unit is still in protect mode, than the output transistors are probably shorted and the unit will again require service. Upon return from service, I would turn on the unit without speakers to insure that the unit at least works that far. Also, if you have an ohmmeter, measure across the speaker terminals. You should read either 3 or 6 ohms. If you read 0, the problem is a shorted speaker that then shorted the amp.

Keep us posted.
