Macintosh Classic CRT cathode crackling
Hi, is there anything I can do to fix the cathode in this Apple Macintosh Classic? When powered on there is crackling sparks and a loud crackling sound. No image is displayed. Image links:
Is the CRT done for? It’s a pity because the rest of the computer is quite tidy and in pretty decent condition.
Appreciate the help very much. I have checked a lot of manuals both found nothing with regard to this particular issue.
