I took three non-consoles to the local repair shop and they were all diagnosed unfixable. The Super Nintendo only flickered in black and gray lines, the N64 doesn't send any signal except when immediately turning it on it send a gray line and the Dreamcast goes black after the initial screen, which he told me it was the processor. Are they really gone? I promptly replaces the SNES with a SNES mini, the N64 with a jungle green version, and the DC with the black Sega Sports version.
