    17 inch NECmonitor

    I have a 17 inch NEC crt monitor that has lost its display, there is a constant clicking sound when monitor is power on, the sound appears to be coming from the flyback transformer, I attempted to discharge the high voltage anode, and there was no stored voltage present, double checked with voltmeter, reading 0 volts, is this normal, or is there no voltage getting to the anode, I did the check with monitor unplugged of course. Any thoughts would be appreciated.

      if its the one i am thinking of the h.o.t. is shorted and the converter fet is also.
      caused by bad solder joints on the h-driver transformer and fly.
      fet=2sj306
      hot=2sc5047.
      beware of fakes!

              what i went through dealing with my mobo with dead onboard sound!
              by ChaosLegionnaire
              so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

              i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

              Monitor Audio RSW12 - Green light, but no sound
              by MOSSEP
              Hi

              Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

              Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first β€˜decent' bit of audio equipment I ever purchased and is a little sentimental.

              The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

              I have already tried replacing all of the...

              HP ProOne 23.8 inch G9 ALL-in-One Desktop PC - Working when plugged to an external monitor, no image otherwise
              by Coguar
              In the device manager there is no built-in display located. The Intel UHD Graphics are displayed and only the external display is visible. The AiO turns on and works but is only showing a black screen on the monitor.
              I checked the voltage on the backlight connector and it reads ~20V. I tried reseating the LVDS and Backlight connector, yet the image still does not show.

              Does anyone have ideas whether or not this is a BIOS related issue? The only visible log in the BIOS logs is that the firmware was updated around a month ago.
              We already tried to fix it by resetting the...

              Dell 34 inch U3419W Monitor with thin stripes on partial screen
              by ChristianBr01
              Hello everyone,
              I have a Dell U3419W Monitor that has some thin stripes on a part of the screen since Tuesday.
              This lines cover about a third of the screen and appear for 2 seconds before disappear for another 2 seconds.
              This repeats the whole time. I have not opened the case yet cause I had no time, but will try to fix it on this weekend. For me, it looks like a problem on the TCon... Am I right?
              Does someone have seen this before?...
