Ive had a matrix chip installed for over a year with few problems. Recently however every once in a while my box would reboot a couple of times then the led would begin to flash green and red with nothing on the screen. It would eventually start to work again until today. I tried realigning but that had no effect. Once after flipping the switches on the chip a couple of times I got it to work but only for a short time. Even with the chip removed I get the same problem. Any ideas? Thanks
