Sorry this is all a bit rambling. I've seen a few threads with this issue already but no obvious solution. Here is the situation: I have a single Roamio DVR with just one TV, a cable card and Tuning Adapter - probably the simplest setup possible. My provider is Time Warner/Spectrum and I'm in Rochester NY. I've had the Roamio for several years without any problems until a few months back. Then I started to get an issue where the TA would have a solid green light and then flash 6 times and then solid green again. This would repeat every 70-77 seconds or so, seemingly forever but see below for more information on this. When the light flashes the picture goes away and the Tivo stops recording everything in progress. This would happen every 2 weeks or so. I contacted TW cable card support and they would have me just reboot the TA using the following sequence: 1. Unplug the USB cable. 2. Power cycle the TA. 3. Reconnect the cable. Sometimes, after this happens, I only get the broadcast channels but if I wait long enough they eventually come back. This has got progressively worse so that now it is happening once or twice a day. I must have called tech support about 10-20 times about this issue. They have sent 4! techs out to fix the problem. Most recently last Friday (5 days ago) and yesterday. This morning, when I got up, the light was solid green and working fine except that I was only getting broadcast channels. I used the remote to change channels to see what channels I was actually getting and suddenly saw the 6 flashes again. My theory is that trying to change channels while I wasn't getting the SDV channels caused the 6 flashes issue. Although that may just be coincidental. The TA was reporting the RDC out of range but rebooting seems to have fixed that. Which makes me think the issue is with the TA. The topology is very simple. On the outside of the house there is a splitter. One output goes down into the basement and to the cable modem (never had any problems with Internet access). The other goes into the wall and directly into the back of the TA and then out from the TA into the Tivo player. I tried putting a splitter before the TA, so that the signal goes to the TA and Tivo and not through the TA but that did not help at all. So currently that's not there. When the techs come out all they ever do is check the signal strength, tell me it's fine and then mess with the wiring outside the house, anyway. The first three replaced the splitter outside the house. The last one replaced the cable from the splitter to the TA completely. I have requested that when they send a tech out that they send out someone familiar with tuning adapters but so far that hasn't happened. I have had 4 different Tuning Adapters. The fifth one should arrive in a day or two. I think this is my second cable card - not sure on that but I have a replacement arriving soon. At least one of the TA's that I have tried was practically DOA. After I plugged it in it flashed consistently for at least 6 hours and maybe as many as 12 before it finally started working. That isn't the one I currently have. The previous TA's have all been picked up at my local TW Office, and I'm pretty sure they are just recycled. One time I returned the TA I witnessed the agent toss it into a large box behind him, not placed but tossed! I wonder if this is why I am getting so many problems. When I called in on Monday before the latest tech visit, I got pretty annoyed at TW and asked for the call to be escalated. Instead of putting a manager on they put someone on who was just another tech pretending to be a manager. I know this because I recognized his voice as someone I had worked with in the past. I asked for a different manager and as far as I can tell he might really be a manager. He also claims to be the highest person I can talk to at TW. I asked them to overnight a NEW TA and cable card, but was told that was impossible and that they could only send it three day delivery. I doubt that I'll get a new one. It's being shipped from an address that looks like a TW office about 200 miles away. He also scheduled a tech who came yesterday. I asked that he send one conversant with TA's and he said he would certainly do that. However, the tech that arrived admitted he knows nothing about them. The night before the tech arrived the problem happened at around 9pm. I think it was exactly 9pm. I thought, "Great, I'll leave this in a broken state and he'll be able to troubleshoot it." Sadly, when I got up the following morning the flashing had stopped, but it was not fully working I was only getting broadcast channels, the V53 error. A short while later though the other channels appeared too. Now looking at the TA diagnostics - it looked like it stopped flashing at exactly 3am. Not sure if that's when TWC send out a signal or not. As mentioned earlier, this morning I checked the signal levels from the diagnostics page. The RDC was 0 and then 5 and then 10. All of which are way out of range, but after rebooting the TA it was 37, which I think is good. I called TW and asked them what the next step to fix this would be if the replacement TA didn't work but didn't get any kind of satisfactory answer. At the moment I'm waiting for my replacement adapter which I hope will resolve the issue, but if anyone has any other suggestions as to how to fix this I would be very grateful. Or indeed, if anyone has any suggestions on how to get TW/Spectrum to step up and make an effort to fix this. Other information that may be relevant. TA is at F.1901 I recently upgraded my Internet speed from 30 to 100 (not sure if this coincided with the start of the problems). TW/Spectrum recently went all digital requiring everyone to start using a cable box.
