I have a TRS-80 Model 4P, one of the earlier ones with the white screen.
When you first power it on, the display is very bright - lines across it and everything. After about two minutes, the lines go away but the display is a little dark / fuzzy. If I turn up the brightness, it gets the lines back.
Are there replacement displays I could do for it? Or something else I can try?
I just replaced the power supply - the old one started started acting up and the display started pulsing brighter and the fan was spinning up and slowing down. I turned it off and replaced the PSU before any damage could occur.
Any ideas?
