| SE and noise on screen |
Posted by: CharlieFrown on 2023-05-28 00:53:52
Hi,
I replaced the broken CRT with the working one „borrowed” from my Plus. It works apart from the fact it gives me random noise/mess on screen - like suddenly appearing horizontal bars and such. They are not solid bars that are on screen entire time.
Any suggestion will be appreciated. |

I had similar issues on one of my builds and it was due to the neck board solder joints coming loose (the part that is attached to the neck). I would inspect/reflow those as well as the connector on the analog board. |

ObeyDaleks: thank you so much for giving me a hint concerning neck board. Totally forgot about resoldering those joints in SE/30 many years ago. |
