Hi 1024mak,

Thanks for the advice I will give the connector a good cleaning and see the result.

Hi 1024MAK

Many thanks to you

Hi Guys, I am using a DIVmmcx2 (from 8bit4ever) with a ZX spectrum and all working good. I would like to use it with a 128K +2 Grey case Spectrum. The manual is stating that jumper settings are the same for both ZX Spectrum and the 128k +2 but I just cannot get it to work. I am using the same SD car...

Here is another video showing the nasty interferences on a white background.

Ok so I have the pinout for this scart cable : :D DIN LEAD -------------- SCART PIN Pin 7 --> green wire --> pin 11 Pin 3 --> black wire --> pin 13 Pin 5 --> brown wire --> pin 20 Pin 2 --> grey wire --> pin 8 Pin 8 --> blu wire --> pin 7 Pin 4 --> yellow wire --> pin 16 Pin 1 --> white/purple wires...

Hi Mark

First of all thank a lot for your interest on this matter. I will do as you asked and open up the scart box and din lead to see how the wiring was done. I will report back

Hi Paul,

No clue of what has been done in the past. I still did not get my hands on the motherboard. I will open it and have a look at the capacitors. I have noticed that patterns may change sometimes to a very grey interference. It could be a bad solder joint on the video DIN socket.

Hi Rwap,

This is the scart cable. It looks like being the original provided with the Spectrum if it was the case at the time the Spectrum +2 was sold. Note that the labeling on the different ports is in french on the Spectrum case.

Hi Guys,

I just got a Spectrum 128k +2 from ebay. It came with its power supply and the scart video cable. The machine is working pretty good but when hooking it up to the TV I just get a lot of video artifacts as per this small video. What this can be??

Hi guys Very happy with my ZX Spectrum now that I am using a video converter to hdmi which gives really a sharp picture On an LCD screen (by the way the Spectrum has the composite mod) The only issue I have may be this strange waving of video screen especially on bright colored areas as you can see ...
