It has all the information you will need to fix it. The main circuit diagram is only A4 but being a PDF, you can print it to any size - I did it on two sheets of A3 and it didnt lose any detail - just made it readable when pinned up above the bench. I've found the fault, just need to buy some obscure bits to get it going again!
I cant fault the process, I paid for the manual in the morning and it was ready to download by lunch time.

Very good copy in a 54 pages PDF archive. This is my sixth purchase here. :)

Another excellent buy! File too clear and explanatory.

A manual hard to find. It was very helpful to restore my device.

I am very grateful for this manual. Without it could not repair my receiver.

LED FLASHING CODE
PURPOSE: The led indicates the power mode, occurred I2C error and On timer
INPUT:
Current power mode - I2C Errors - On timer
Processing: - If in STANDBY mode and On timer inactive then switch LED off. - If in STANDBY and On timer active set LED to blinking, (switch on and off at 1 Hz with a 50% duty cycle). - If in POWER-ON mode, switch LED on. - If an I2C error occurred, let the LED blink at 1 Hz, 50 % duty cycle. For the blinking times see the Table below.
Note: Only when an I2C error occurs for a number of times, or for a number of seconds, the I 2C error is handled by the system (that is ,only then the set will go to standby, the led starts blinking).
