With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

The following page can help you troubleshoot the problem if you want to try to repair it yourself.

Picture will not come on

A few questions and a suggestion:

Do you get sound? Does power light stay on?

suggestion:

Unplug set and remove back cover---set will have several green led lights on board in power supply and one red one.

Red one should be on. While looking from the back have someone turn set on---note if all the green led lights come on and if one or more go off before the others you have located your problem.

The green LED's monitor voltage sources in the set's power supply.

I have more ideas but need more info from you.

If this helps rate this solution as very helpful as I do this here for free.

Green & Yellow light on 14.4V charger

It sounds like your battery is bad.

If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.

Lights on Rechargable Lantern.. Swissgear SG66301

I don't know how to solve your problem but, the three lights mean this:
Red LED light indicates the battery is being charged
Green LED light indicates that the battery is fully charged
Amber LED light incidates that the battery power level is low - the battery needs recharge.
Do not recharge you battery over 24 hours.

No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

HELP PLEASE. NAD 370 JUST DIED...

This could be as simple as a bad connection at the voltage regulator IC or blown output transistors. If you have a multimeter and some experience with electronics repair, this should be fairly straightforward.

Let me know and I'll try to walk you throught the repair.

American pro amp 1000 watt vs=3503

The Protect light would normally be Red. You need to test your RCA's and make sure your getting a signal to your amp.  I would just buy a new set  or if you have another set just try them.  If you get your amp to power on and all of your voltages are right with the proper signal and your amp fails to turn on you Have a bad amplifier
