led backlight tester
« on: February 21, 2020, 08:41:44 pm »
hi i was watching utube videos about building a TV backlight tester first schematic i found plain dont work so was in the posses of building another variant based on 555 timer when a friend gave me a electronic ballast/evg  model sh70-z hep group 240vac in 350v out which is about the same as the scheme i was making my question is will this thing be suitable or am i going to get the biggest shock so far?
