Hi
Yes I will post all photos when I get them and I have made myself a purpose screwdriver with wire and croc clips I used on a sharp mz 80k my virgin moment on discharging a crt (oh baby).
My only what if is the video I posted at the begining
https://youtu.be/sR6CnaRWPoI
where the same pet as mine no display and it was a ram chip at fault.
I am only a very poor novice and rely on the expert advice given by the members on here
which is very much appreciated but just a thought I had is if the crt is ok and it was a memory issue then the test rom would prove so.
shoot me down and tell me I am stupid and I will bow down to the forums superior knowledge I am just looking for the simple fix if possible.
many thanks
