Hi All,
I have two Powerbook 160s where nothing seemed to be coming on to the screen. I have recapped the screen and invertor board with like for likes.
Both of them are now working, but I'm getting the kind of interference I would expect of a failing/failed screen.
I've documented as much as I can on this thread over at 68kmla (https://68kmla.org/bb/index.php?thre...-screen.40029/).
I'm out of ideas and do with some help diagnosing.
I have:
- Checked with ESR the caps and they match what they said
- Checked continuity from pad to pad on each replacement
- Given everything a general clean
Interestingly, if I switch it to monochrome mode, there is almost no ghosting at all - it gets slightly worse for 4 colours and then really not good at all for 16.
I also have a general shimmer across the screen which suggests to me a dirty power source of some sort? I've tried the original PSU as well as after market.
What would you test next?
