Re: Video left/right jumping glitch with RGB

Made some progress - the TV is getting confused and trying to switch the colour system rapidly. Question is how does it work it out, I notice the CSYNC level is highest on the machine which does it the most. Not a huge difference, about 0.3v. If I set the colour system manually (to anything!) then t...

Re: Video left/right jumping glitch with RGB

Found someone on Youtube with the same problem and cable - mine does it much, much less than his.

Video left/right jumping glitch with RGB

Still having lots of 'fun' with now three grey +2s. Unit 1: perfect aside from noisy audio linked to screen brightness Unit 2: same audio as above, occasionally jumps approximately a whole character block to the left then right again Unit 3: quiet audio, does the same left/right picture jump but mor...

Re: RGB from grey +2 - no sync

Ignore this - I feel like such an idiot.... I had a composite source still physically connected (but not turned on) at the front panel which shares input 5 on the back.... Now it's fine (although still not on the CRT which is weird but not a problem)

Re: RGB from grey +2 - no sync

Update - plugged it directly into the big LCD and that sync fine although the picture is a little dim. Doesn't work at all on an old Panasonic CRT still. Is there any way to make these switcher friendly? Not sure why it's even upset given the wide variety of absolute garbage signals I put though her...

RGB from grey +2 - no sync

So I bought a +2 on ebay, it's the older grey type and I then bought a 128/grey +2 RGb cable from retrocomputershack. Testing on my Sony LCD or an old Panasonic CRT I keep for just this kind of problem, both of them exhibit what looks like rapid horizontal and vertical rolling - you can just about s...

Wanted: tape deck part for +2

Long shot but does anyone happen to have any +2 (grey older type) tape deck parts or completely ruined computers? I need a plastic gear from the play mechanism, the one on the other side of the pulley for the second belt - just one screw releases the sprung arm/pulley/gear.
