Posted by: olePigeon on 2023-08-30 11:34:39 Try zapping PRAM?
Posted by: David Cook on 2023-08-30 11:36:57 Have you tried it since it has cooled down? Also, try a different slot
Posted by: SophieRose on 2023-08-30 11:40:42 Tried pram... tried all slots and tried original apple card which works fine. 😢
Posted by: Phipli on 2023-08-30 11:57:12 Tried pram... tried all slots and tried original apple card which works fine. 😢 Hum. I wonder if a VRAM chip failed like others have said based on the initial symptom. Otherwise... I've heard that those BT RAMDACs used to fail. Good news is there is someone selling those RAMDACs on ebay.
Posted by: Phipli on 2023-08-30 11:58:33 First easy thing to check (it won't be it, but regardless), is check the crystal is OK. Do you have a scope?
Posted by: SophieRose on 2023-08-30 12:26:45 My scope is 80 miles away 😂 .. the ramdac might be worth a shot. Thanx

Posted by: Phipli on 2023-08-30 13:01:25 The eBay listing for the RAMDAC is sold out, but just so you know, the ADV473KP110 is an equivalent part. Have you checked for lose pins on the chips?
