    That green diode or whatever it is called on the left and the 2 caps to the left of that I think may be bad.Look at your last pic and you will see the browning from the caps and a dark spot like the solder is broke wher that green cap thing is located.Check it out and let me know

    Default Sonicview SV8000HD Power Supply Repair

    This is a little write up which I would like to share with all the fine users on this board.

    As I originally stated, I started having re-booting problem. It did not happen very often in the beginning and the receiver was even re-booting when saving SVLan network settings. I got fed up and measured all the voltages on the PS connector leading to the SV8000HD main board. The voltages I got were very close to the ones marked on the PC board.

    I got a bit discouraged. I thought that if the power supply was OK and main board was OK (because of the two green LEDs were OK), it would be just the software issue, I tried force booting and nothing happened, with unit’s front LCD panel being dead.

    I have visited a lot of boards, read a lot of messages, talked to many people on this board (you know who you are), and here is the solution:

    One of the measured voltages was reading 2.7 volts instead of 3.3 volts. I though that due the tolerance it was an acceptable value. And that was the problem. The voltage must be 3.3 volts or better.

    01. Remove the existing D6 (Photo 1, Photo 2 and Photo 7)
    02. Remove the existing C10, C11 and C24 (Photo 1 and Photo 2)
    03. Install new Shottky Diode D6 (Photo 6)
    04. Install new capacitors C10, C11 and C24 (1000uF, 10V)
    05. Add fans (see photo 3, 4 and 5)

    And you are done. Voltage went back to 3.3 volts. Unit is booting fine. Everything is working great (touch wood) for now.

    I would like to thank PURROCITY for his input. In fact, I am dedicating this write-up to him only. I personally believe that we have to help each other and he did.

    Hi all. I seem to have a similar problem with my 8000hd. i have replaced c10, c24 but not c11 or the d-6 diode. when i power up the front panel is dark and i hear a fast clicking on the T1 transformer, then is stops after about 10 seconds.
    all ov my voltages seem to be right on
    5.04
    12.26
    3.30
    23.90 (+and -)
    27.78
    i think my voltages seem good
    Do i still need to replace the other parts also.

    thanks bill
