Hi.
AV Famicom from the very first batch - serial starts at 10002xx.
After 10 minutes of operation, artifacts begin on the screen. After restarting, Everdrive may show an error reading from the card, it may start scrolling through the menu itself, or it may simply not load. I've tried several versions of Everdrive that work without problems on another console. In the only regular cartridge - RAF World/Journey to Silius, after starting a level, it switches to the next level in a second and runs through all the levels before the credits. Test cartridges write - work ram error. All this after 10 minutes of work, before that everything works fine. I felt all the components on the board with my fingers - nothing above 30 degrees is heated.
I tried to change the capacitors, power adapter, 7805, HC373, both memory chips, PPU - nothing helped. I did not change only the CPU and bu3266. If the CPU can be removed from some old broken ordinary Famicom, then there is nothing to replace the bu3266/3270. And as I understand it, it's probably about him?
