Amiga Hardware Issues and discussion / Re: VERY Dim video output from Amiga 4000
« Last post by Retronaut on April 30, 2024, 12:45:18 AM »Thanks Castellen, an update.. I noticed that if I pressed just to the side of the DAC (between it and U211), the image got a little brighter, though it required quite some pressure.
So in case of a dry joint, I reflowed the pins on that side of the DAC and also on U211. Also the jumpers near there, just in case. No change.
Its lat here now, but I'll give your Capacitor info a look tm. It makes sense that if C460c went wonky, then it would modify the brightness. Me and my friend discussed this. But I did not know the expected voltage out of it, and I did not have a method to measure it in circuit so...
I'll try the heating first. Fingers crossed its this, a pretty simple fix if it is!
