AVTECH 717 DVR firmware

[RAJEEV 0]

Hi I am facing a peculiar problem, i tried replacing the lithium battery for date/ time back up, after that the dvr date and time can not be set , it immediately goes to default ( 01 Jan 2000) also the dvr goes to stand by mode after power failure ( does not goes to on condition automatically when power is restored/

does any one think it is bcoz of firmware

if so can anyone suggest where to download the firmware

 

Thnx

I would try a hardware reset. I doubt the firmware would fix your problem.

 

The chip may have a problem that goes with the battery. You may have a battery that came off the shelf that may not hold a load. Test the battery under load.

I agree with scorpion, new firmware will not fix such problems-if it would, it would mean that the original one was semi-functional from the start-and that is impossible!

It's more or less a hardware problem, I would go for electrolytics or bad capacitors around CMOS if new battery and hardware reset don't help.

I alreaye tried the hardware reset, but no help, also one major issue, the dvr does not show video on LAN ( it shows the homepage but after you enter the username and password the video can not be seen ) p.s. it actually logs in and you can access dvr settings from LAN, on the other hand you can see video by connecting a TV monitor to the DVR ,

also which chip needs to be checked for date time error...?

I shall appreciate quick help folks..

This sounds more like an Active X issue unless you do not have Java loaded on the computer.

Thanks for suggestion, but the pc has Java, I can access other DVRs of same model perfectly well., Any idea which hardware components to check.....

I have started a parts page and I got as far as the AVC 760, and the economy crashed, and this project lays dormant so I have not gotten to your DVR, but you can check to see if it uses the same parts as the 760.

What signals do you see on the board with a scope?

 

Are you sure the clock oscillators are working?
