    Good CRT, I got the same and it's terrific! And, yes I'm the 999 sub here! Hope you soon get the next one! Cheers, M

    I have a 1084S that's making the same noise, and also had a short on the same header. I'll have to check the caps to see if one's shorted now. Thanks for posting this video, it's probably saved me a ton of time.

    I found my old childhood 1084 monitor that was still in the original box at my parents basement. Very good shape still and everything is working. Great idea about adding the SCART. My serial number is really close yours actually. I have a couple questions. When adding your scart connector were each of the pin vias filled with solder when you removed the ground plane? Also, did you have to discharge the CRT each time you were working on the pins? Awesome video and thanks for the walkthrough!

    Hello I have a Bang & Olufsen that has no standby light tv was on then turned off by itself and I can't get it to turn on. Where should I start please

    Im trying to repair this monitor and found your video. It helped me to find a broken "bt151 500r" but it's still not working. The power supply makes a high pitched sound. I tested the transistor that is attached to the heatsink but it appears to be good. Can you give us any hints on what could be wrong?

    @Andy King same issue with my 1084S but no shorts on the pin header from the PSU to the main board. Checked Capacitor in question but cap is ok, changed it any way. Still same issue, would you have any suggestions ?

    Hi...is that metal bottom plate, ground plane?, necessary, I see some commodore 1084, 1084s monitors without one.

      I have never tried without it because I never checked with a schematic to make sure all ground was common without it (i.e. does the PCB connect all grounds or did they do something dumb and rely on that metal plate to do it). If you see two exact same models, one without a bottom plate, then I assume it is not necessary for that model. But probably will reduce the chances of interference.

      @@treminaorugx I sort of had the same thought....but the soldering of such a large metal plate close to nearby PCB traces and pins underneath might cause a short, if not careful.

    Hey, I've watched a few of your videos and I'm curious about something. Why do you install a SCART port when you can? Is there a benefit to doing it, or is it just a personal preference?

    • @treminaorugx
      @treminaorugx  2 года назад +2

      SCART is just one of several types of connections used for RGB video signals. In this case these monitors have a spot to put a SCART port because in Europe SCART was a standard for analog video for a while. These days we are using SCART globally as an RGB connection for our retro consoles so its just convenient to have a SCART port directly on the monitor instead of having to buy several adapters to connect SCART RGB cables to the commodore RGB port.

    My 1084s works but is smell on burned electronics so bad that i cant use it…

    • @treminaorugx
      @treminaorugx  3 года назад

      I would imagine it's full of leaking capacitors then. Going to need a major cleanup and recap to prevent corrosion and smell

      @treminaorugx  3 года назад

      If it has no power LED and no display then you probably have a similar issue to this video. Power supply likely has at least one dead component which needs to be replaced. Be very careful and if you aren't experienced with electronics I suggest you don't try to fix it because power supplies are dangerous.

      It realy was a very interesting video and a nice channel to learn something about the trash i collect on my privat graveyard (my cellar)
      Maybe one day i try to learn repairing all the stuff by my self.
