Whilst watching TV yesterday, the tv just switched to standby and the media receiver switched from a solid "on" light to the "on" light flashing 8 times and then a short break and flashing 8 times again. We are now unable to turn the tv on again without it switching to standby. We have disconnected all the cables and noticed that the "black" cable that goes from the back of the tv into the back of the media receiver is the one that is turning it to standby. When the cable is disconnected, the tv will flash red and green but it will not switch to standby.
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
