My 620 watt is stuck in protect mode why is that and how can i fix it?

Hi Xuong, try to follow these steps, it may be deactivated automatically:

Open Toshiba Assist -->> Protection and Reparations -->> Device of diagnosis PC-- >> Device Driver -->> Graphics card and Computer and reactivated it.

If you still stuck in that issue, dial my number +1 (833) 493-0111 (toll-free) number.

Thanks,

My crunch powerzone pzi2250 1000 watt 2ch amp is stuck in protect mode. How do I fix this at home

this is usually an anti theft precaution taken where if the amp is tampered or attempted to be stolen it will shut down making it useless for the thief the only way to get them unlocked is usually by the people whom installed it for you or the manufacturer

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

The unit will need to be repaired by a technician. Most likely you have a bad transistor that is causing the protect mode to turn on. The only way to get the protect mode to turn off is to remove the bad part.

Think of the protection thing as a fuse. So the cause of it going off will be an overload in the power supply or main amp. Check all the parts in those sections, you might see something burnt or damaged, pay close attention to anything on a heatsink.

A 1000 WATT AMP HAS PROBABLY GONE INTO PROTECTION MODE BECAUSE YOU ARE TRYING TO RUN 1600 WATT SUBS COMBINED

Hello ace_sterling,

Not knowing what you have the SPL-620 driving or knowing how you have it wired, it's rather difficult to determine if it's wired "wrong".

I show the SPL DK2-620 as being a 2-channel amp with 150 watts output at 4 ohms, or 180 watts at 2 ohms. Even if the power is somewhat overrated, it should provide more than enough power for a set of standard 2-way or 3-way speakers, or component speakers with a separate crossover.

Powering one or more subs is another thing. You would get sound, but the subs would not be very loud. In bridged mode, the amp is only stable to 4 ohms. So if you are trying to power 2 4-ohm subs, the best connection would be 1 sub connected to each channel. If you are powering only 1 sub, then the bridged connection would be best.

Hope this helps. If it does, please rate as "FixYa".

If you power up the amp with the RCAs plugged in, does it go into protection mode.

If you power up the amp with the RCAs plugged in, does the woofer pop?
