Dead TDS3000B (3054B) , possibly processor?
Mrnt:
Did you make any further progress on this? Curious as to whether the processor needed reballing.

Hello,
Many apologies for the exceedingly slow response.
To cut a long story short, it's still an ongoing project. I have a new processor and I need to get the old one removed and the new one in it's place.
However, that is all easier said than done due to the density of the main board. I'm working up my BGA de-soldering skills, but I'm not ready to risk the board yet, but it is my intention to get this done sooner or later.
Best
Paul.

Well I know it has been a year and a half since I last posted on this thread, but I *finally* got around to removing/replacing the Motorola Processor BGA.
I replaced the chip with a new one purchased from Motorola/NXP
And.....drum roll.... **No Change** :-( :-(
Same symptoms, blank screen with white back light and fan running, no other activity
So after all this time, I think that was a 'red herring'
Hmmmm....
