  • More trouble after new power supply in Series 3

    My S3 was rebooting at the Almost There... screen when both cable cards were installed (it worked fine with 1 or none). Since HD passed both the S.M.A.R.T. and Overnight tests, I assumed the PS was the culprit.

    After installing a new PS:
    - First boot it went to a blue screen after the Welcome, Powering.... screen with the OLED blank and all 4 LEDs lit
    - It sounded like the HD was spinning, but it is hard to tell.
    - I had checked all the connections well on the HD and SATA to the MB, before closing it up, but was beginning to doubt myself.
    - Unplugged it and waited few minutes and tried booting it up a 2nd time before pulling it all a part again, but the same thing happened with the blue screen.
    - I then pulled out both cable cards and disconnected the Tuning Adapter and figured I would give it another try and see if I could get into the Kickstart menu to test the HD again (easier than pulling the TiVo out of my entertainment center and taking it apart again). This time it got stuck on the Welcome screen with all 4 LEDs on. I waited a good 20 minutes to be able to hit the pause button and it was just stuck there.
    - Frustrated I unplugged the ethernet cable and tried one last time before pulling it a part again, but this time when I plugged it in, the fan powered on, but no OLED or LED's and no signal to the TV over HDMI. Again it sounded like the HD was on, but can't be sure.

    Each time I did something it just seems to get worse. I opened it back up again and all the connections look good. I am not feeling good about this. I have lifetime subscription on this unit and I am thinking I have lost the MB.

    Any suggestions?

    Well after leaving it sit unplugged for almost an hour, I tried it again with no cable cards, tuning adapter or ethernet plugged in.

    I got Fan, HD spin up (quite certain this time), LED's and OLED and made it all the way to the Almost There... screen. I walked away and came back in 5-10 minutes and it was completely black again. No signal to the TV over HDMI and no LED's or OLED. The fan was still spinning and the HD sounds like it was too.

      Are you sure it isn't just that you need to press the "format" button on the front of the unit to toggle it to a format that your TV can read?
      Been here a long time . . .

        My TV supports all 4 formats that the S3 can output.

        However I went ahead and tried it again just to see if pushing the Format button could help. When I plugged it in, I got the 4 LED's lit, but nothing on the OLED. The TV registered no signal and nothing changed when I pressed the Format button.

        I unplugged it and let it sit for a few minutes and tried again. This time not even the LED's lit. The entire front panel of the S3 was black. No Signal to the TV. Fan was spinning and so was the hard drive.

        I am beginning to think I have a problem on the main board. Have you guys ever encountered anything like this? How would you further diagnose this problem and what kinds of repairs can you do on the main board? Or is this just a lost cause?
