Hi everyone, I have inherited with my building a dvr with cctv, I am told that it is an AVTECH 4ch machine with a removeable HDD draw no USB or LAN, and has no indentification on it except a small label with PR770KIT-4 S/No P03050168, all has been well until a power failure it re-booted ok then the next day all the led`s were lit and I could not switch it off as no buttons would work, I switched it off by the wall socket waited a couple of minutes and switched on, the HDD was detected as the message on the monitor said but all the LED`s remain lit, I have no picture from the cameras and can`t get the menu up as the buttons won`t work. Has anyone incured this problem before, is it a simple fix or do I need to replace the DVR. Any suggestions willl be gratefully received.

Hi, I will take your advice, there is a small computer repair shop a couple of miles away, I will speak to him he may even be able to repair it if it`s not the supply. yes I agree there are fewer and fewer repair shops now, sign of the times with the throw away attitude and the way things are made these days. I will also keep you in mind if they cant repair it, and take your advice and go for the 760A model. Cheers!

Can anyone help me more on this, just getting ready to chuck DVR in the bin.

Hi Hio sorry have`nt replied been on hols, I have checked the voltages, they are ok coming from the transformer but on measuring the plug into HDD from the circuit board I have 13v and 4.95v is this a significant drop to affect the unit, I have also found out that it is an AVtech av770 unit is there a fix or do I have to bin it?

Hi do you think it is the transformer or a bad connection, there are a few pins/conectors in the power plug, is there only one 5v and one 12v pin and where do I connect a meter to measure the voltage, I mean which pin is the negative, cheers
