Hi All,
I opened mine up yesterday to upgrade the screen to something a little nicer. The old screen was getting hard to see and was starting to fade a little around the edges. The AK is very well designed internally and very easy to open up. You have to be careful lifting the base out as there are ribbon cables connecting between components.
De-soldering the old screen is a bit involved and time consuming, all I could focus on was not damaging the existing PCB pads with the de-soldering process. With a little careful help from my screw driver, the old LCD came out eventually and I was very relieved when it did. For someone with experience this is not a difficult thing to do, definitely not something to attempt by the in-experienced.
Cheers,
It’s been a while but I’m sure this is better. The original screen was quite underwhelming. One thing though, this screen isn’t perfectly black like the advert said but it’s far darker and offers better contrast than the stock screen.
So the situation is that my machine is putting out too much backlight, not sure why, its definitely a black screen. I will need to put in a 2-3k resistor on either the ground or +5v and that should fix it. It is still far better than the old screen, I am seeing new symbols, numbers and icons on the screen I never noticed before!
Yes, very happy with, I know someone with the original screen, its almost completely faded now. The install is not hard if you have the right tools, knowledge and experience. The hardest thing is removing the original LCD, there are many solder points to remove, I used a solder vacuum (solder sucker) This was essential I think. The install itself just requires soldering experience and a low heat and good solder. Although the new screen is amazing, If I installed a resistor pot I could have dialled in the brightness, its too late though once its soldered down.
As for a MKII, if it were 8 voices then it would be a no brainer purchase.
