I got tired of not being able to record anything from the TV, so I replaced this 'bad' unit with another I had lying around.. I tend to collect HW it seems...
When I put the replacement into place and tuned to a channel (everything connected is exactly the same between old/new boxes), I saw the 'no video signal detected' notice
then it resolved and showed the actual received video signal.
I honestly hadn't been paying that much attention before, but having to use a cable company-provided cable box includes now a bit of a delay (before the 'upgrade' to digital and using Replay's own tuner, I don't recall this slight lag) when changing channels, and at first, the Replay doesn't see a signal, but then it will sync up and show the data. Apparently the box that suddenly went south has lost that last step ability to resolve the signal being received.
If I see the signal change when I change channels, but the Replay simply can't seem to sync with the incoming signal and display it, is that a Power Supply thing? Everything else works.
As I mentioned, I have something of a 'pile' (I'd say 'bone pile', but as this mound has been growing since PHVS2000's (about 19 years), I cannot say that the units are all 'bad')...some have just suffered different issues over the years...I think the first was a 'stuttering to death' issue where the box just lost all video synchronization and would stutter rather than resolve a signal...I've had blue screen of death, stuck at 'please wait', etc...and when I wasn't able to resolve the problems, it was cheaper and faster to just get a replacement box...so, now I think there's probably at least 5 (maybe 10?) Replay's in the pile... I failed to add notes to each body as it was added to the pile, so I cannot say exactly what each unit's problem may or may not have been
I never expected to have such a mound.....
Anyway, maybe I can Frankenstein a repair? Anybody have specific instructions to suggest for me to attempt to resolve this box's problem with 'no video signal detected' by doing tech swap and pop of parts from other units? Are we talking about PCBA soldering, or just disconnect/reconnect parts? I can solder, but not having a good thermal controlled system (just household tools), I worry about nuking boards/chips....
At one point, I had 4 Replays all working at once...over failure compounding time, it's down now to two. One had this 'no video signal detected' issue when I got back from vacation...it's been pulled and replaced by another unit that is (for now) working....my other, sadly, also had a problem I found...why they wait until I'm on vacation, when all I ask of them is to keep recording things while I'm away..you know...their JOB....I'll never know... This second box seems to have gone south (stopped recording) about a week ago
When I turned on that TV to check, the Replay was pulsing on the 'Please Wait' screen
Note: there were no power outages or anything like that while I was away (or other things in my house would have been whining).
Leaned on PWR button. No bueno
Power Cycled. Same
So, having learned over the years, I pulled power and all inputs (Coax, RCA connections)...I left the outputs alone since that's not usually the issue... Left it in that state for a little over an hour. Plugged back coax and signal inputs (RCA cables) and then powered it back on...magic. It's now working again...
As for the launch point of this post, well, one more on the 'mound', and if anyone out there with more savvy for the guts of these beasties can suggest what I might do to repair this 'no video signal detected' apparent video signal sync problem, please let me know.
Thanks for assist
