A3000 tick & fuzzy screen

[alanh]

Hi,

I've got an A3000D and when powering up from cold the screen tends to fuzz on individual scanlines all the way down the screen as though certain scanlines shift a few pixels to the left and right randomly for a few minutes.

After it's warmed up they tend to clear up.

I've just plugged in an ATX power supply and it's clean.

Is it possible that the TICK signal can cause this ?

Mine does the same thing, regardless of the TICK jumper setting. I dunno if they all do it, or if there's some age-related component failure. :shrug:

Mine does this as well, for maybe 30 seconds or so and then it's fine.

 Ancient capacitors are the common cause to this type of behaviour.

 Swap all motherboard/PSU electrolytic capacitors for new units and you guys are covered for the next 10/15 years. ;-)

Also mine does this, but after a couple of minutes it goes away. Only on the VGA output.
