my old reliable TMA-1 become older. Now it got a new effect, at start the display start glowing but no chars are displayed. It can be fixed by a cold start and will work for some time after that.
So i did a maintenance, cleaned the plastic band connector on display back side, fixed it with fresh tape. One of the white connectors had a broken contact, so i soldered the flatbed cable directly in with glue fixation. The white plugs on the main board look like ordinary tin contacts that suffer from oxidation, have cleaned them.
Excited how long this will help, do the display have a rubber2glas contact strip that age too?
