  • Re: Copy-protected DVDs

    Funny I had the same thing just happen to me with an external drive. I just tossed it in the trash and put an old internal DVD drive i had laying around in my PC. Those things are all such cheap junk now it's no surprise they fail so easily.

  • Re: how to achieve admin rights on win10 tablet?

    Boot to Win10 install media

    On install screen hit Shift+F10 to get to command prompt

    switch to C drive

    copy c:\windows\system32\Utilman.exe c:\windows\system32\Utilman.bak
    copy c:\windows\system32\cmd.exe c:\windows\system32\Utilman.exe

    Reboot tablet, at login screen click the Ease of Access button, it will launch a command prompt, net user Administrator *, Enter, Enter and that should remove the Admin account password


    And I agree with you, the whole idea...

  • Re: Tivo Series 3: Green blinking light of death



    No, the hot air "trick" never actually did work for me. The owner of the board says it worked for him. Here's what I have done so far

    Swapped the 3003 chip & 3002 chip, both are chips near where the hot air was applied
    Swapped both large SMD caps in between those chips
    Recapped all the AL SMD the entire area (14 caps) and put in 25v caps to replace the old 6.3v ones
    Swapped the voltage regulator in the area
    Swapped another chip labeled U11 in the area (that several of...

  • Re: Tivo Series 3: Green blinking light of death

    Well, I recapped the board where the hot air was being blown, no dice
    I also jumpered from a known 1.37v source to Test Point J, still no dice.

    I did find a chip that was shorting across several legs, and in my board it was not, I swapped my chip over to the bad board but the shorts were still there, so I am going to follow all the traces to everything that chip is connected to and check it out. This is a real challnege to fault find

  • Re: Lifted trace, how to glue back down?

    I usually replace the trace/pad with a small piece of copper tape that is a little larger than the original trace/pad, then apply conformal coating around the edge of it to bond it to the board.

    I've had bad luck with Superglue, I can get it to stick but when I try and solder to whatever I glued down it usually comes back off again. But that's probably me just doing it wrong

    I don't have a scope, and my son dropped his dumbell on my ESR meter and I haven't gotten a new one yet

  • Re: Tivo Series 3: Green blinking light of death

    Think you may have been onto something with the AL SMD caps.. I was looking at the caps and getting the values, and in my working Tivo, ALL the caps are Panasonic, in the other about 1/2 are Panasonic, the other half are not, I'm not sure who the manufacturer is.

    Also, there is a bank of 5 large capacitors that on the bad Tivo are rated for 6.3 volts. On my Tivo they are rated at 25 volts. And those 5 capacitors are right where the hair dryer was blowing. AND Test Point J is connecting to one of them. So that's a lot...

  • Re: Help identifying Aluminum Electrolytic SMD cap values

    So I have two Tivo's and it turns out the other Tivo has all Panasonic caps, so I can read them all. the first one has a mix of manufacturers with different codes

    So in the interest of posterity in case anyone stumbles across this in the future and is looking for similar Cap values, here's what I got off the other Tivo:

    Cap #1: 22uF, 35v
    Cap #2: 15uF, 16v
    Cap #3: 220uF, 35v
    Cap #4: 220uf, 16v
    Cap #5: 47uf, 35v
    Cap #6: 1uF, 50v

  • Re: Tivo Series 3: Green blinking light of death



    I'll keep probing

    I have a can of freezing spray to find overheated chips, I will give it a shot. I may just blind swap the RAM chips to, there are only 4 of them and I need the hot air practice.

    I will mention that the Tivo is not mine, and not essential, so if it is unrepairable it's no loss, but I would love to get it working again.

    Thought on the 1.3v injection to that CPU pad?...

  • Re: Tivo Series 3: Green blinking light of death

    One other thing, when I first did the CPU test point measurements, test point D was also showing 0.33v, upon inspecting the board I found a bridge on two legs of the first memory chip that must have happened when I reflowed them. I wicked away that bridge and D started showing the correct 1.30v after that. So it could be a RAM issue?

  • Re: Tivo Series 3: Green blinking light of death



    Well, All I can say is the capacitors in that area read the correct voltages, and the 5 I have removed tested correct capacitance on my multi meter. I have not removed all of them and don't have an ESR so you could be 100% correct in your initial assessment. Turns out removing SMD caps is not a specialty of mine and traces were getting torn so I stopped.

    The board does come to life, the fan spins, the HDD spins, the CPU heatsink gets to the normal warmth. But it gives that blinking green light error...

  • Re: Tivo Series 3: Green blinking light of death




    So the first thing I tried was using my hot air station to reflow everything in that area, but it didn't help.

    I happen to have a spare old Tivo HD that works fine, it's a non lifetime unit so I have no real need for it, but I figured I can use it to make like for like measurements between the two units.

    I spend about 2 hours checking voltages on everything in the area that the hair dryer trick was performed, I checked every capacitor (yes there are several SMD Capacitors there), resistor,...

  • Tivo Series 3: Green blinking light of death

    Anyone familiar with these old Tivos and the blinking green light issue they can develop?

    Someone sent me one that is exhibiting the issue, and I've been taking reading around the board and comparing them to a known good Series 3 Tivo motherboard I have, and so far the only different I can find is a difference in diode reading on a voltage regulator. However when I swap over the voltage regulator from the good Tivo to bad Tivo, it shows the diode readings of the original component, so something else is causing the issue

    Power supply is good so I know it's not that....

  • Re: Synology DS1520+ no power

    stj is right, sounds like a short or something else drawing to much power, and the power supplies protection circuity is kicking in

    Open it up and look for anything obvious. Then follow the power rails and start testing the transistors along that path and see if one of them failed. That was the issue with a amplifier I had that was doing the same thing.
