So yeah…the soldering iron was on so I decided to continue!
I have now removed:
9x Surface mount resistors (these things are fucking tiny 0402 size!)
1x Tiny ass SMD transistor and two larger transistors
2x Fuses (for the CFL tube)
1x CFL tube
Remember when I said it uses a CFL tube as a backlight? Here it is! Literally a mini flourescent tube!
Before laptop and desktop LCD’s went LED they also used CFL’s but they are super thin and run along the edge of the screen typically, not like this thing that has a mirrored reflector too! Early 90’s tech gotta love it.
You can also see the flat flex cable that connects the original screen to the mainboard. To remove that I had to PEEL it like a bit of tape! I was wincing when removing that!
To give you an idea of how fucking small some of these components I have been removing are:
Meet R44 forever removed from the board with a pen for size comparison.
I have also replaced the two cap’s in parallel that I had in place before with a properly sized one and also one other (you can spot them as they are no longer blue in the pic below)
Its now ready for a voltage check to make sure its not making more than 5.45v (this would blow up the new screen if it exceeds that) but I’m not expecting mine to be doing more than that as the old girl is healthy
I’m taking a break now but my desk is hilarious right now…its covered in bits of game gear, components, bits of paper with diagrams on it and other detritus
