    Thank you, Pete, for this great video it saved my life! I bought the keyboard in the States and was shipped to me with other things, but the screen was dead. We tested it after using your video and found that the lamp was fine but was impossible to find in South Africa when we first thought that it was the bulb. After more testing, we found that the 300mV capacitor was gone, again no store in South Africa had one, only had 100mV. So plan Z I put a LED strip in the place of the lamp and it works. It's a little bit bright but after working on it on and off and a hundred phone calls, hours of searching online for over a month it's finally working. Very embarrassed to say that I did not listen when you said that we must put a few screws in and test it, I went ahead and put it together only to find that the screen was upside down. I put your video on again and redid the whole thing and it works great. Thank you very much, my friend.

      Kim, This means a lot to me. You are the exact type of person that I did this video for! Thanks for your kind words. Glad I could help.

    Thanks Pete - super helpful.Managed to change the display just with your video. Small point for anyone else - there are two ribbons connecting the keyboard section to the display/processor unit which Pete’s video clearly shows. There are also two cables; the first goes to just below the pitch and mod wheel and the second goes to just underneath the right hand switch above the pitch and mod wheels. On my unit the connectors on the processor had been fixed in place with a red glue so had to be disconnected from the other end. Lastly, suggest you turn up the display before reconnecting and re-inserting the screws as it is long winded to have to go back. Thanks again to Peter - the PC3 is a great keyboard with a poorly designed display so its great to be able to fix it.😀

    Nice job Pete. Looking good 👍Remember ! The new display is LED backlit. That means none of the temperature problems associated with the old ccfl backlit display apply.

    Thanks for this video. I was fortunate to get the LCD as replacement from Kurzweil support under guarantee and I did a similar procedure to replace. Kurzweil support rocks. Good to know there are other options available in market (LED screen).

    Thank you for showing how to open the keyboard. I have one that boots up to a pure blue display only. Now I could open it up. Hade a look and cleaned the cable connectors, but sadly that was not the problem. Guess it is some component.

    Was the pin-out for the new display the same as the old? I've got a new panel ready to go in but I haven't found a definitive answer to whether or not I need to reconfigure the pins. I'm afraid I'm going to blow the new display at power up.

    • @petehanratty950
      @petehanratty950  2 года назад

      My replacement part was a direct match pin for pin. Actually I didn't check that before connecting, I just plugged it in.

    Hey Pete, Thanks for this video! I noticed a thin grey two wire cable coming off of the new display. ( at 6:51 and 7:12 ) I didn't see you hook that up to anything.
    Is that possibly supposed to go where the other wires were cut in order to have brightness and contrast adjustability or ?

    • @petehanratty950
      @petehanratty950  4 года назад

      No. I ordered the display with brightness control, that's what the two grey wires are. They are hooked to the new brightness pot. Instead of drilling into the chassis I just set it to where I liked it and left it tywrapped inside the instrument. The original contrast pot still works as always. thanks for watching.

    Pete, Thank you for the video. After having my display start going all wonky and displaying illegible garbage I was able to open it up and what I found was the red wire of the ribbon cable appears to have broken loose from the display board. I'm hoping and assuming this is the case as the wire was just hanging there with nothing "safe-ending" it and the board has an open pin on the connector. Might you have any thoughts or advice to fix this? I'm contemplating taking a soldering iron to it. Thanks

    • @petehanratty950
      @petehanratty950  Год назад

      Which end of the cable is the problem? At 6:36 in my video you can clearly see the display end of the cable is connected, I'm not sure about the other end. If there is no pin where you want to connect to, I wouldn't. manufacturers use that to 'key' the orientation of the ribbon. Maybe look into the schematics if you can. Best of luck.

    • @raydiognome
      @raydiognome Год назад

      Thanks for the reply . I can clearly see in your video a 6:36 the display end and that your "red" wire is connected. Mine appears to have broken at that point. I think I will try to pull out the bad pin and reconnect the red wire

    The replacement display costs around 25-30,-EUR or Dollar. When you are able to modify it on your own, you easily save even more money.

      Could you please give any direction in how to modify a standard $20-30 LCD for a PC3 or provide a link to the info?

    • @Kaffimusic
      @Kaffimusic 2 года назад

      Be aware, besides the electronic modifications you have to make a mechanical adapter to fit the new display into the housing. You can ransack the old display, you just need the circuitboard as mounting plate. Bore new holes for the new display and use nylon standoffs for mounting. The new one is way lower and shorter. You need to bring it close to the window. EDIT: The link to the mastering vast forum has been deleted. This is where a discussion about it was done. Search for the forum, and then use the sentence "flashing display and questionable" - exactly these words to search for the thread. My postings are from 2020 including pictures.

      @Kaffimusic 2 года назад +1

      @@ShallRemainUnknown I had to write a how to... which I did not. Well, but you can go the same steps I did: Check the pictures closely how the contacts are set, how the modification looks and the parts used. The only things not in the picture are the trimpot for brightnesscontrol (it is at the end of the grey cable) and that adapterplade made from red plastic, including standoffs to make it fit mechanically. Just slaughter you original board, you have no use for it anyway, you need to drill some holes into it while feeling merciless to mount the standoffs and the new display on top of it. The grey ribboncable goes into the old connector and with the trimpot the juice is reduced to what the LEDs need. I soldered my cable directly pin for pin to the board. You need it to be very flat and can not use anything higher than what is in the picture as pre-manufactured parts. Or it won´t fit under the adaptorplate (which is the same format as the old circuitboard) This new display needs less energy than the old one.

    Thanks for this - clear and very helpful. I'm just fitting mine now, and have a question: on my board there is a pair of wires coming from the old display and soldered to the main board (one white, shown as "return", and the other blue, marked "hot"). I'm guessing these aren't needed on the new display, so can I just snip them and leave them?

      Right, at 6:38 I show that you can cut these wires pretty closely and not replace them. They are not needed for the new led backlight. Thanks for watching.

      @@petehanratty950 Thanks Pete also for the video. It saved me time getting my Kurzweil apart. No I don't have the part as yet but it wont be mounted on the back bracket panel. I have already got a nice piece of aluminium 2mm tick and cut perfectly to size and drilled. It fits in perfectly where the old display was. When it arrives I just have to use spacers to mount it on this panel. Its not difficult.
