    Default Sonciview 8000 HD no display, how I fixed one.

    Had a buddy say his SV8K had no display. He said it failed slowly over time in that a reboot would fix it until, finally it had no display at all. Also HDMI out did not work, I did not test other video out. Both green LED's on PCB would still light.

    I checked all voltages on the PSU and noticed the 12VP was out so I replaced capacitors C67 and C68, rated 220uF, 16VDC. 12VP came back but still no display.

    On further investigation caps C64 and C66, rated 470uF, 10VDC were bad. I think the 5VP appeared OK on the DVM but checking the associated caps using a cap meter showed they had failed. Replace those two and the unit came back up, both display and HDMI.

    I have repair a $h!t tone of SV8K and have never seen the display fail. Kind of weird both circuits were VP circuits.

    Anyway I hope this help someone one day. Probably me when I forget I fixed one before LOL.

    One of the things that makes the 8000 such a good unit is the fact that they were such a pleasure to own:that gave smart people the incentive to fix them & share the knowledge gained.Best unit of all time
