AB to CRT socket?

Have you unplugged the Floppy drive? Worth a try with BMOW rom. Caps, clean board, remove RAM and clean RAM sockets. iI no go SWIM as cheesestraws suggests

Thanks for that I knew the 575 was a drop in but hard too come by at a sensible price now. Seems to be a few 5000 and 6000 series boards about at a reasonable price so was curious. cheers

Will those boards work without mods in a colour classic?

Looks like ROM chips may be swapped around and something else as well causing half screen.

Likely

Congrats beware the Mac bug has bitten!

I'd adjust the vertical and horizontal size via the analogue board, screen is a bit too big.. Check your 5v as well. then fiddle with the yoke magnets in the middle on each side. The easiest way I have found to get the screen size and aspect correct is to use the black and white squares...

The AB is a new old stock and works perfectly with plus board. I suspect the LB maybe memory or? thanks

Thanks have checked this

Hi Brains Trust. 512k bongs and the screen displays expected startup for about a second then black. Anyone experienced this and can head me in the direction of possible culprit/s Cheers

Maybe the smallest drop of light machine oil?

I've done a bit more exploring. I've pulled one apart and the power supply works (yes I am aware that they can bite). Had a good look at the 512k board and it looks good, next I'll give it a good clean up and test. The cases are very basic but I think I'll retro and tidy up and reassemble into...

I plan to get at least one working and then tidy it up as a restored example

Ordered the rgbtohdmi see what happens
