Hello, I was hoping somebody may have some pointers on a Cop DVR it powers up and whines no picture there is no obvious signs on visual examination indeed it looks like new in and out the only thing noticeable is a very twisted lead to hard drive thanks hoping some one has an idea for me to follow up.

This is 2010; my 2009 model crystal ball has failed. While we have very intelligent people here, even they can't do much without at least a few pictures.Originally posted by cctv

Re: Cop xt 09 cctv dvr
Check the voltages on the black/red and black/yellow connector. Red == 5v, Yellow == 12v as a start. The little cans on the board are capacitors. If any of them look swollen or they have leaked onto the board, they are likely damaged.
Does the fan come on when the unit is powered up?
There is a label that says "remove seal after washing" Maybe you better wash the board and remove the seal... heh
I would also suggest getting a picture of the power supply board.

Re: Cop xt 09 cctv dvr
No need to wash the board, but that tag should be pulled. It was supposed to be removed after the board was wave soldered and washed. Most modern wave soldering involves a flux that evaporates in the soldering process, but the tags are still used.Originally posted by cctv

The power supply, a Top Power mini atx 250 watt has cooked in places, so after I find one with a rear mounted fan that will fit I will see where I am thank you for the assistance so far.Comment

Hello Everyone,
I have an Onkyo TX-SR353 Audio/Video Receiver (5.1 ch with HDMI) that I am having a really hard time diagnosing and I'm about to throw this in the junk and go buy a new unit that is on sale until the 7th.
Symptoms:- Intermittent (part of the reason why i'm having a hard time isolating problem), sometimes will work for 10+h at a time without issue
- Original symptom was wife reported loud banging noise (like someone was banging on the wall with their fists) from the LEFT SURROUND speaker and then the unit shut off.
- I swapped the Left and Right surround

Hi, we have a number of Streamax X5-E0804 vehicle CCTV recorders that are dead - they all have a power supply PCB with 5 10F 2.7v super capacitors which have leaked and buckled, but replacing them doesn't fix the fault. Digging deeper it seems that there short circuit somewhere, but so far I have been unable to locate the faulty component. its a long shot but has anyone come across these DVR's or better still have a schematic? -
Hi,
I have an external CCTV microphone photos attached. The two cables (green and blue have come off the little microphone chip) however the pad has gone off the chip when someone dropped it.
There are a few metal bits poking up but solder wont attach as the pad has gone. Is there a way to repairing it? (I can solder) I was thinking of trying to attach a trace pad to the metal bits to see if it joins.
I have seen online some of them have the copper pads further down. Could I scrape the top off and go straight to the pad that way?

Hello all just wondering if anyone knows how to do a hard reset on this model, XVR58C-21D-8CH-V1.1 ?
There are videos on youtube for every other model but this one, I do not have the switch on the board or reset jumpers.

I do have 2 little pads right next to the firmware chip, I have shorted these and powered the system on and waited a wile
with no luck. I will add picture of these 2 pads.
I do have the bin file from the firmware if its any good to anyone maybe able to edit out the pass I am not sure.

Hi all, won't go into details but managed to cook it myself.
Has two sets of codes on it.
Top code JWN8T
Just below code 2GL 4B
PCB code ZM11E-T30 V2.1
Out of a Hiseen CCTV monitor with no model of course....
