Problem with DS-7204HQHI-SH/A(B)

[Sigibert]

Hi
I have the VCR installed as of July 2016 working properly all the time. Last week VCR beeped almost continuously, but cameras and VCR were transferred to app. I powered of the VCR. Now it does not boot any more Power LED on for a second TX/Rx for a fraction of a second only.
Who had a similar problem and how was it resolved?

As a long shot - disconnect the HDD and see if that makes a difference.

Thanks, I will try this and revert (only coming Monday very busy in upcoming days

Hi I have disconnected HD and VCR boots but beeping continues. There is one alarm signal displayed at one of the cameras. I will try to disconnect this one.

Hi I have disconnected HD and VCR boots but beeping continues.

So it boots now but didn't with the HDD connected?
And now beeps due to no HDD?

 

[Sigibert]

Did not help, connected HDD again, looking to configuration there is no HDD, so I will replace this one as a next step. Thanks for your help Sigi

 

[Sigibert]

Apparently it is looking for a HDD, which is configured and not there since it is broken. I tried to boot with broken HDD again, this time it did boot.

I tried to boot with broken HDD again, this time it did boot.

That pretty well confirms that the HDD is the cause of the problem.
Could have been worse!

My wifi hates that noise when I set up a new nvr as it takes a few minutes to shut it off when the hard drive is formatting it’s self

 

[Sigibert]

I will revert as soon as I have a new HD Thanks for your comment

Yesterday I have connected a new HD 3,5" like original, but beeping did not stop, no hard disk detected. Next an old 2,5" 160 GB HD, this one was detected and worked for a while. "Defect HD" formatted in other device and was o.k., "new HD 3,5" formatted in an other device was o.k. as well. 3,5 " HD new again connected into Hinvision again with my ear on HD. There is a noise, like HD tries to spin, but does not succeed, then beeping starts.
My conclusion Power supply to 3,5 " HD maybe not strong enough to operate an 3,5 HD. The 2,5 " HD worked for 6-7 hours then beeping started as well.
What next????

 

[alastairstevenson]

What next????

Well, you have confirmed that there isn't an HDD fault but there is a hardware fault of some type in the DVR.
Suggestion:
Eliminate the HDD cables, power and data, from the cause by substitution.
Check the power supply voltage to the HDD.

 

[Sigibert]

Thanks, do you have en idea on specification of required voltage to HDD?
This one maybe
Black: Ground,
Orange: 3,3 V,
Red: 5 V,
Yellow: 12 V

 

[alastairstevenson]

Thanks, do you have en idea on specification of required voltage to HDD?

5v and 12v are what's needed to power the HDD.
Did you do those measurements with the HDD connected?

 

[Sigibert]

No I measured from socket of mainboard. Currently I am checking with supplier, the warranty of Recorder, actually 36 months on all Hikvision hardware

No I measured from socket of mainboard.

Possibly may be sagging under load. The fact the 2.5inch was OK for a while and 3.5inch was not may indicate that.

Currently I am checking with supplier, the warranty of Recorder, actually 36 months on all Hikvision hardware

Well, good luck with that, it does seem that there is a hardware fault.

I have experienced a lucky end, the VCR was replaced with a new one within warranty period
