Sick CDTV: black screen, but runs programs

[Daniele Gratteri]

Hello to everybody! Many wishes of an happy 2010! :-)

Unfortunately the last days of the 2009 made my CDTV sick: it doesn't
display screens anymore, both via RGB or composite (from the genlock)
output. It does run software on CDs and on floppy disk, e.g. I can hear
the typical sounds from the drive made by Workbench while loading.

Has anyone got an idea? I tried to replace Denise, but got no luck. I
think Agnus does manage memory too so I hope it is not the sick
component, being an 8375 on a MegAChip.
Can someone point me to a good troubleshooting guide?

Thanks!

When RGB failed too I would suspect a faulty Vidiot (video hybrid). See

for a similar case.

Thanks for the tip, it exactly seems to be my case!
