Why there is a flashing red light to the back of my dvr and flashing power light and flashing hdd light

You might have a bad HDD, try removing the HDD and restart your system. if it works, you may need to repair/reformat your HDD through a PC or else replace the HDD...goodbye to your recorded videos...goodluck

Yes, and yes.

The HDD light shows when there is disk activity.

My DVR box is powered up but, i get no picture and the HDD red light is flashinG

I had the same problem. Did their online tech support and Patty told me to hold down the "rewind" button on the DVR for 20 secs. You should now be able to right click your mouse to access the on screen menu. You will now want to go under system, and a/v setup and change the device to VGA instead of Vout. Now you can reboot and not have to go thru holding down the buttons anymore. Worked for me.

It should only take a few min's.

By default it goes to VGA port out of the DVR.
So you could hook up a pc monitor to it and use that. Once logged in you can change to tv out via the desktop menus.
It is also possible to hold down a button on the DVR (cannot remember which one sorry) at DVR power up to switch it to use tv out instead of vga.

tv will not power on. red light on switch blinks. power relay clicks, but no picture or sound.

The internal power supply to the HDD is often suspect in these units. Check you have power on the internal plug to the HDD from the circuit board. if you do not Try fitting an external HDD power supply (£15) this cured my unit which had a similar fault.
Hope this helps - good luck.
