I have a problem I cannot figure out with this set.I am not getting power to the light by the power switch,the light would not come on and everything pointed to the power supply so I purchased a new one from tsm,but that did not fix the problem,this is what is happening,when I plug it in the relays click,and if I hold the power button down for about 5-10 seconds the relays click and then the red light will come on.If I unplug the board to the right tnp-a4183 the relays will not click,but if I unplug the board to the left tnp-a4182 the relays will click and the red light will come on if I hold the power button.I THINK that the board to the right might be the problem,has anyone ever seen anything like this.

I would suggest that you reconnect all connectors you may have disconnected, plug the unit in and WAIT, for at least 5 minutes. Do not hold the power switch down, simply WAIT. During that time the unit should show an error code. (blinking power led) Count the number of blinks between the pause's. The code will help diagnose.
