KR-v 6050 amp

Hard drive failed, replace it

Hello noella_30 - Typically DDO indicates that the washer has detected a problem with the dispenser drawer. Either the drawer is open and will not close properly or a professional needs to check reed switch.

Look at your memory card. SD/SDHC cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

Check the speakers one by one, maybe one of them are damaged and make the device going on protection

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Start with the paper itself. Make sure it is in the machine properly. Here is a short guide on a few things to check:

You need to make sure you ohms are correct if there too low this will happen to protect the amp.

E210 Lens problem


Lens is stuck, or can not go to home position, check motor and sensors

Make sure you speakers are turned on on the receiver,

I would suspect the protection circuit is bad (bad cap). It worked before??
Find what is driving the speaker protection relay. Replace the small electrolytic caps in that section. Small caps are used so that when the power is removed the relay releases quickly. Or DC is present on one or more of the amps before the relay.
