    thanks for the time and detail of your post. my moms toshiba sd-h400 wouldnt boot past "powering up" so she had brought it to me because i knew that was an hdd issue having known my own dvr. after replacing the hdd, then came the "no signal detected on: cable in" video issue within the tivo gui, which was unexpected. It was troubleshooting a couple weeks to try to figure out a combo that would work to no avail. (ex. coax only, composite only, mix, etc.) i got soo frustrasted after a couple google searches, i put it up for sell and sent back the tivo wifi adapter i bought for it.

    well, within the next week, i was prepared again for a challenge so i plugged it up and whoila...i have a cable picture. lol. now i stopped the potential sell of it and had to get those accessories back like the tivo wifi adapter, etc. by the time i got them back, i had been through a power outage, guide info had run out, and now im back to the "no signal detected on: cable in" video issue. lol. then i started the google searches again and came across a lot of people with this issue and this post was very helpful and also another as far as how to connect up tivo to cable box on another site. i hadnt noticed the live tv yellow button not being on anymore (but recall seeing it light up the room) and the rf in nub was a little loose but after tightening from outside..still nothing. so i opened the tivo casing(while unplugged and always ground yourself) and got my butterknife to undo those pesky metal clamps at the top of the rf casing. it looks like the metal part that touches the rf in is in place but i still tried to force it closer in with a screwdriver. well, i then plugged it back up and have live tv on the front of tivo and picture on the screen! that is too crazy. i, like others, was getting cable after turning off tivo, through the tivo rf out so that gave me hope. also, when plugging coax from wall to tivo and coax from tivo out to tv after pulling it out of the closet..i thought i had another chance to get it restored.

    i currently have it working through my cable box. i would suggest have coax from wall to cable box in, composite cable from cable box out to tivo composite in, and coax out from tivo to tv.. it is switching channels on the cable box with the ir cable. also, when going through guided setup, it said "found video signal" on composite so that made me happy. im a moxi person but i take from my mom in that she likes dvrs i suppose. we will see if it stays working when i send the tivo back to moms though...lol. it should be ok but its a hassle when power is interrupted for any reason.

    update: my mom got the tivo and although live tv didn't work after she 1st plugged it up, 1 powercycle of the box and its good to go. i hope power isnt interrupted anytime soon.

    I know this thread started a couple years back. I am not sure if folks just gave up, but I have not really seen any real solution with the problem that so many of us have been plagued with re: the Toshiba SD-h400. I have the exact same symptoms that others have mentioned. Video feeds through the tivo just fine when it is in standby but when powered on, get the screen that shows "Searching for signal on cable box in. see 'messages & Settings' / ' Troubleshooting' for info." I have tried all the remedies listed here, but get absolutely no where. I can watch the shows that previously recorded and am able to transfer shows to the sd-h400 from my other series 3 but because it does not acquire the cable box's feed, it does not record any new content which is a real bummer! My tivo is hooked to a Motorola cable box with the serial cable and the tivo changes the channels on the cable box, however they are all the same black screen with same message. It would be nice to know if someone out there has found any kind of solution to this problem. Mine started when my UPS went out and tivo powered down. It is almost like there is a time limit built in to this model to stop working after a specified number of years or hours?! I Bought the Lifetime Subscription for mine years ago, and upgraded the hard drive back in 2007 and it has been working very well for me up until now. Any help out there at all? I am willing to try to get this thing going again as I need the recording live t.v. capability! Anything? Anyone? Help!

    Sounds like some of the TiVo software got scrambled when the power failed.

    Perhaps changing to the alternate boot partitions would help.

    WinMFS has a fixboot thingie, option 1 sets you to boot from 2,3, and 4, option 2 sets you to boot from 5,6, and 7.

    mfsinfo tells you what it's set for currently

    I think there's supposed to be a kickstart # that toggles you to the other set, but I'm not certain. 51 or 52 maybe.

    And furthermore, pull the drive and run the manufacturer's diagnostic long test.

    You should be able to find it on the Ultimate Boot CD.

    And furthrer furthermore, suspect the power supply of capacitor plague.

    unplug it for a few days and pray that it shows a tv picture when re-plugged.

    I just encountered this exact same problem with my Toshiba SD-H400 after a power outage yesterday. I've cycled the power several times (including leaving it unplugged for about 20 hours) with no luck. I'm running through the guided set up now and keeping my fingers crossed that it will fix the problem, but I'm not all that hopeful.

    Any other new thoughts on this problem (other than what's already been mentioned in this thread)?

    It's a very strange problem in that the Tivo system operates fully (can scroll through the menus, play recorded programs, etc.) and it's just the live cable will not go through. Definitely makes me think tuner, perhaps I will open it up and see if anything looks out of the ordinary...

    Well, just for anyone who stumbles across this, here's a quick (and unhelpful) update. Finishing the guided set up did not fix the problem; I then did another power cycle or two (don't remember if I did it twice this time or not?) and surprise surprise, it turned on and I have live tv. So now I guess I'll just hope the power stays on and this doesn't happen again!

    This topic is old, however the problem obviously still plagues many of us so I wanted to share my experience with this issue. I have two of these boxes and I have had them for many years working without issue using the "tivo basic" service. It seems a somewhat common thread with a lot of these problems is the unit(s) losing power suddenly from something like a power outage which is something we just had here the other night. I woke up to BOTH units displaying the same symptoms/problems as covered in this thread and they are both hooked up in different rooms in completely different configurations. One is hooked up to a cable box being commanded by a serial cable, input is RCA cable and output is COMPONENT video. The other unit is hooked up using a DTA converter via COAX and output is Svideo.

    To resolve this issue I have found the following. There is a setting in the menu/settings options under "Video" called "Change video input" or something to that effect and basically the unit detects which input is being used and attempts to switch you to a different one..I.E. if you are using the coax input you can switch to RCA input or the other way around.

    Our unit with the comcast DTA box would not work no matter how many times it was reset as others have noted when doing a power toggle of the unit you could in fact see signal was passing through. Going into the "change video input" the unit acted as if the only option available was to plug in RCA cables..it gave no other choice. What I did which immediately resolved the issue was I disconnected the DTA and plugged in the cable line coming directly from the wall into the tivo's analog input. Our cable has been completely switched over to digital so there is no way it will be able to tune a channel but my thought was maybe it will see the signal. After connection I went back into the menu/settings for video and selected "change video input" and it immediately asked me what channel did my tv need to be on to display and then it asked me if I could see the video in the background which I could(however it was a warning message from Comcast staying to hook up the DTA). I then completed the setup it told me I successfully changed my video input and I moved the COAX cable back to the DTA and connected the DTA back to the tivo input and it was 100% working as normal.

    Hopefully this may help someone in their own troubleshooting, I just wanted to share my experience since I was able to resolve the issue after many failed attempts at resetting/unplugging, etc, etc.

    Congratulations, you're a genius!

    Or at least clever and determined.

    But check the power supply caps anyway.

    I'm sure you know way more than I do being that you have 8k posts on a TIVO forum/community but I read all of the posts from page one and nobody mentioned the menu setting I did as far as changing the INPUT it *thinks* it is using. I have two units both had the exact same issue after a power outage and both were resolved using the same method essentially introducing it to a signal that for some reason it could no longer detect in it's configuration it was in before the power went out. IF you try to swap the input method with NOTHING connected, the unit will not let you do anything so it KNOWS there is something plugged in to it be that a coax cable or an RCA, etc. If that has something to do with power supply caps then sure, check that I have no idea I'm just trying to help by adding what to me looks like new information to a topic that is several years old. Take it or leave it I guess. :)

    I was sincerely complimenting you.

    You thought of something that would probably have never occurred to me.

    But those units are of the correct vintage to be at risk for strange symptoms caused by power supply problems caused by "capacitor plague", so it's a good idea to eliminate that possibility as a part of the troubleshooting process.

    Photobrian, how did you fix your TiVo that was connected to the cable box via RCA? Did it give you the options to connect RCA when you tried to change the input?

    Cool, no problem. I honestly wasn't sure if you were being sarcastic or not. I do have some background in troubleshooting and diagnostics etc but I'll be the first to admit I know squat about a TIVO.

    The other one connected VIA RCA I restarted the tivo and the cable box (unplugged/cycled) with no RCA's connected then connected the two together while powering up. I'm thinking it has to do with needing the signal input to be tripped. If it doesn't see input on the RCA, it defaults to coax input so you can ask it to switch if it doesn't do it by itself. It's happened in the past and a combination of those things has always brought it back. The one on the DTA/coax has literally never had this problem so it was strange when being connected differently they both had the same problem albeit slightly different resolutions to what I believe is the same problem. I just want my tivo to live forever. :)

    While setting up S1s and S2s so that I could "tune" to channel 1 or channel 0 and get whatever was being fed into the line iputs (RCA jacks and S-Video jack), I'd have to lie during Guided Setup about having a satellite receiver connected.

    I discovered that I'd also have to have an active video signal already on either the yellow jack or the S-Video jack before starting the satellite receiver part of GS or it wouln't ever give me the chance to do it.

    So apparently there's something in the TiVo DNA that freaks out over a lack of signal where there's supposed to be one.

    When I go to change the input, it tells me to hook it up from the cable box to the TiVo with composite cables. I hooked it up with composite as it tells me and still I get a black screen.

    I tried to hook up the DTA as Photobrian stated and it continues to tell me to hook it up with composite RCA cables and produces a black screen (which it does with my other Series 2 as well, but that works).

    Any other suggestions? Unitron, I looked at my power supply and there doesn't appear to be any bubbling of capacitors, is that what I should be looking for? I am almost ready to write this off as a loss since I have been working at this for 10+ hours.

    While I go back to to read this entire thread, tell us what equipment you have, what you're doing for cable and satellite and over the air, and what your problem is.

    My SD-H400 is connected to a Xfinity DTA via Coax. Output is Composite RCA to standard definition TV. I had it working perfectly with the DTA, IIRC when I did the initial guided setup for this configuration, I do recall that the video hookup told me to connect the cable box to the TiVo via RCA. The input was Coax, but it worked fine.

    Then we had a storm that briefly cut the lights for about 5 seconds. That is when the A/V input from the DTA stopped working. I get a black screen when I try to turn on live TV. When I unplug the TiVo, the A/V passes through to the TV with no problems. To rule out software issues, I restored the image I downloaded onto a different HD with the same results. I even hooked up the composite RCA inputs that came off a DVR. No matter how I connect the input to the TiVo (Coax & RCA), I get a black screen when trying to watch live tTV. It says that it is searching for signal.

    I have the same issue as most the people in this thread, the reset fix didn't work for me. I tried Photobrian's fix with no results. Nothing seems to work at all.
