Recently, I've started to notice that my Amiga 1200 (in tower) has started to develop a strange video output problem that only affects 60hz output (or output using the NTSC monitor driver)
This happens no matter whether it's from a game (WHDLoad or NDOS booted floppy) or from a Workbench friendly app.
My A1200 is of the following spec:
Hardware
- Commodore Amiga 1200 rev. 1D4 motherboard
- Kickstart 3.1 ROMs
- 68040 accellerator: Magnum MKII '040. Unsure of speed (can't remember withuot running SysInfo or similar) & FPU
- 10GB IDE Hard Drive
- 16x IDE DVD ROM drive
- IDEfix 4 way buffered IDE interface
- Internal High Density 3.5" floppy drive (1.44MB PC/1.76MB Amiga/insanely close to 2MB with DiskSpare)
- all in a nice EZ Z4 Tower (http://amigakit.leamancomputing.com/...roducts_id=700)
Software
- Workbench 3.1 (I changed hard drive recently and can't find my 3.9 CD or my 3.5 CD
) - WHDLoad 16.9
- MCP (can't remember version, but it's quite an old ish one)
- MUI 3.8
- MagicWorkbench 2.?
- NewIcons 4.6
- ClassAct 2.8 (iirc)
- all the usual unpackers (XPK, PowerPacker, LHA, LZX, DMS, ZIP/UNZIP, ARC, ZOO etc.)
- Deluxe Paint V
- PPaint 7.1 (for stuff that DPaint can't do)
- Transdisk in C: (you know, the pants command line one that's part of WinUAE)
- and that's about it
Like I say above, I've tried booting from floppy, booting with a minimal WB (so bypassing everything, doing a boot with no Startup-Sequence and typing LOADWB and ENDCLI at the prompt) and obviously a normal startup.
This is looking increasingly like a hardware problem tbh.
Any ideas?
All help/idea/whatever appreciated.
Thank you all in advance!
Cheers
