- After a long wait for my A4000 to arrive, and being much relieved during this
- period to see the many posts here and there attesting to the fact that DCTVs
- work fine on A4000s, now that it's finally here my PAL DCTV won't work with
- it! Has anyone out there got a PAL DCTV to work properly with an A4000!?
- ^^^
- Here are the symptoms:
-
- The DCTV will pass a standard PAL or NTSC screen through and spit out a
- standard composite image fine; in this case, as you would expect, the DCTV
- remains inert, and merely passes the signal through and converts it to
- composite.
-
- Also understandably, if you try and display in an AGA screen mode (e.g. DBLPAL
- or DBLNTSC) it sends the DCTV's composite display bezerk!
-
- HOWEVER, when you display a DCTV image and line it up to the point where
- DCTV normally displays it in all its glory, the composite display goes black!
- Run DCTVPaint and the same thing happens as soon as any DCTV encoded image
- appears - e.g. the gadget panel in DCTV Paint!!??
-
- I spoke with another PAL DCTV owner here in Australia yesterday who had also
- just received his A4000 and he found exactly the same problem with his DCTV!
-
- DO ANY PAL DCTVs WORK WITH A4000s!!?? 8-(
-
- I also have another more minor problem with my dctv. It seems that the pass-
- through connector on it has never worked correctly. Previously I was using it
- on my A3000 along with a 1950 multisync and so never had cause to use the pass
- -through. Now, due to the single video port on the A4000, I have to plug my
- 1950 into the dctv's pass-through. The pass-through seems to somehow alter
- the video signal with the net result being that the 1950 shows a much darker
- display with noticable thin vertical banding and a purple stain down the right
- hand side of the screen. 1081 and 1084 monitors plugged into the pass-through
- (with the A4000 displaying a standard HiRes Pal screen that they would normally
- display without problem) seem to refuse to sync properly, with the screen
- rolling and skewed.
-
- This more minor problem seems to be a problem with my particular unit only.
- As it is now out of warranty I wonder if anyone has had a similar problem
- and if there is any easy way to fix it??
-
- Can anyone shed any light (preferably of the pseudo-24bit composite type)
- on either of these problems???
-
- With apologies to Dire Straits "I want my, I want my, I want my DCTV!..."
