Hot Cap ZX Spectrum Repair

A huge thank you to the sponsor of this video https://www.pcbway.com This ZX Spectrum arrived with serious display issues, and the culprit turned out to be the U21 chip. In this video I track down the fault, replace the bad part, and bring the machine back to life. If you’re into Sinclair ZX Spectrum repairs, retro computing, or just like seeing old 8-bit hardware restored and working again, this repair should be right up your street. **NEW** Patreon patreon.com/morefunmakingit MAIN CHANNEL! https://www.youtube.com/@MoreFunMakingIt BlueSky https://bsky.app/profile/morefunmakingit.bsky.social Ko-fi page https://ko-fi.com/morefunmakingit Amazon Wishlist https://www.amazon.co.uk/hz/wishlist/ls/I5EGNMXIW5PC?ref_=wl_share Discord Channel https://discord.gg/5fmPMzU More Fun Website https://www.morefunmakingit.co.uk/ Facebook https://www.facebook.com/MoreFunMakingIt
