 |  Re: Trying to get my Plus4 working after many years.
Indeed from what I have seen the CPU is the most common cause of a black screen even when the power light switches on as this chip is the heart of the computer and also functions as the video display.
A TED can fail in many different ways but more times than not you may see a picture.
CPU and TED can be taken out of a Commodore 16 and used on a Plus4 if this works out to be a cheaper alternative to get spares. Also a stock C16 with 16k can play 95% of all commercial games ever made. Although my main machine is a Plus4 I do use a C16 to play many of the old games on as it's great for that, spares and repairs are easy to come by and they use a small power adapter which can be replaced with something on the high street today if the worst should happen.
