Hey guys,
Obtained a free A600HD (37.350), minus screws, the HDD, keys...yeah, its a mess!...and as an STe guy, I thought this could be a little project! (hmmmm)
Initially I powered up and it sounded like it was going through boot sequence, floppy drive activated. Second time I powered up, the LED just flashed dim. Tested both RF and AV outputs, but nothing was detected by the TV.
So I did a complete re-cap! no obvious corrosion but I managed to destroy some pads in the process which I repaired using CW2500 and copper foil...a steep learning curve and many hours, but it seemed to do the trick!
So, turned it on and everything sounded good, the floppy drive sounded strong and the LEDs were nice and bright with no dimming. Connected to the TV and RF was detected, AV was kind of detected but the TV kept losing signal. The picture is black and white, illegible, jumpy, I recognise the "commodore copyright" and the Amiga Tick but in a completely broken image. The RF has a similar output but its also scanning up the screen.
I will post an image of what I see, but is there any immediate ideas that you guys might have? what are the typical faults of a CXA1145 chip or surrounding transistors? Tbh from what I can tell, the Amiga is doing its job up until the video output, are there any other tests I could perform?
Appreciate the help guys!
