Re: Having issues fixing comp video on +2 grey.

Thanks Mark, that's actually some useful information that can be actually taken away,

The last paragraph in particular, it might be a case that it's causing a blip forcing a resync making it work, but it's a blip that has a 100% constant. Shame there's not a collection of edge cases to view.

Re: Having issues fixing comp video on +2 grey.

You mean at the same time? If so I have no means of coupling the signal to test at the moment. But I'm using the same rgb to composite cable for both tests, direct in to the capture stick and direct to the TV. I have a few leads to test out, one being the RAMP signal to the TEA, so any naughtiness o...

Re: Having issues fixing comp video on +2 grey.

Wow, don't stroke your ego too hard. I'd like to think you've not bothered to read the thread and just jumped on board because my Amstrad comment touched a nerve. I can only say stuff based on facts I see first hand. I have four other spectrums, two pluses and two rubber keys, only one of these has ...

Heh. Amstrad has nothing to do with it. No Spectrum ever produced a hundred-percent–compliant video signal
Citation? As it looks like you're confusing crappy picture with compliance.

Re: Having issues fixing comp video on +2 grey.

OK, issue solved. I found a TV with composite input and sure enough, it works (as in no pixels in border), so my theory if not the TEA it would be after it was correct. :lol: I guess TVs have a better filtering circuits in them and capture devices and are very particular, damnit Amstrad. FML. Was a ...

Re: Having issues fixing comp video on +2 grey.

I've just realised, maybe the hsync (the white dots) is the root cause, because the decoding on the backend (TV) would be decoding stuff incorrectly, which perhaps means a clocking issue, although that can't be the Spectrum crystal / ULA as it would never recover with the short.

Re: Having issues fixing comp video on +2 grey.

I have a modern TV with scart, I don't have a scart cable as yet, just composite as I want to capture video. Yes, I realise what the TEA does and the realtions ship with ULA (binary logic for RGB and the clock signals) this is why I've ruled that out. This is the problem I'm currently trying tyo sol...

Re: Having issues fixing comp video on +2 grey.

Interesting developments, have received another TEA2000 to try tonight, but if this makes no difference, I can only assume it's between the TEA and outputs, to which I will remove D3 in case there's some issues that side. If I short the luminence output and input delay lines, I lose signal on my cap...

Re: Having issues fixing comp video on +2 grey.

I've just been running some more tests, interestingly, the effect is determined upon power on, by actual power to the machine, performing a reset keeps it in whatever state it was in when powered on, so it's random whether it happens or not, but the pattern in consistent. https://i.postimg.cc/gXtDF0...

Having issues fixing comp video on +2 grey.

I've trying to get a decent image with composite via the RGB connector but failing. I'm still getting severe ghosting and some weird pixels coming through in the border areas. I've done a few things since images were taken and the checkerboard I got rid of with removing C3. I've performed the Joules...

Re: Cannot edit older posts.

What the general consensus on this? I’m okay with the two-hour limbo, but I think special dispensation should be given (or at least considered) for making corrections to code snippets and—if appropriate—to the posts therein. Why can't you just add another post with fixes? Or just link to a blog pos...
