    AOC LM726 made squeaking noise?

    This is the same monitor as per this thread: https://www.badcaps.net/forum/showthread.php?t=7414

    I had replaced the capacitors previously and so far it has been working fine.

    But tonight I sat down at my computer and heard a weird noise like something squeaking, which appeared to come from the direction of the monitor.

    It was not continuous, and happened in bursts of random length. During this there was no flickering backlight or picture loss or anything.

    I hit the power button but the noise continued. Then I pulled the plug, and the noise was no more.

    So I think it was the monitor somehow, but I have no idea what could make this noise.


    At the moment it seems to be working fine now, although there does seem to be random popping\clicking noises (not very loud)

    However that may just be the something expanding while warming up again, it's a very cold night...



    Any ideas\thoughts?

      OK I'm pretty sure the random clicking noises are the plastic case expanding as the CCFLs heat up.

      Still no idea about the weird noise, though. Haven't heard anything yet...

          Removing electrical noise introduced by fan
          by tony359
          Hi all,

          I am working on a sound processor, it tends to overheat so I fitted a fan inside. The fan is connected to the +15V of the PSU via a DC-DC converter based on the LM2596 to reduce the voltage to around 10.5V.

          Unfortunately the analogue circuitry is picking up the noise from the fan in two ways:
          1. The fan is close to the analogue section, the motor itself gets into the outputs so I'll have to move it somewhere else
          2. Even with the fan running outside of the case, there is still some noise which is clearly going back to the processor via power line....

          Onkyo TX-SR805 noise in one channel
          by MegaZAC
          Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.

          Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.

          There's some logic behind it. As soon as I select an input I get only left...

          Denon AVR 1908, High pitch noise on Surround back Left channel after long overhaul

          Hello,

          I know some might say... just buy another one. Sell it as parts..!

          So had this AMP for quite some time. Recently I saw light smoke coming out of the AMP. Had my fire extinguisher close by. Just kidding. Turned immediately all devices off from mains.
          Let things cool a bit, and opened up the amp device. I clearly saw on the main board which hosts the 5X amp (5.1), 3 10 ohms 1W resistors had their leads looking black, while the rest of the remaining 2 x 10 ohms were brownish as being installed from factory.

          Spent some time downloading the Service...

          Problem

          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

          Initially, it started to give random failures, 3 months ago, after which it stopped delivering current. In addition, there was some noise in it.
          After another month he died.
          I thought that some filter capacitor had found its way to the end, so I started doing some research and remembered that there is a really complete review on tomshardware:

          So I started to take it apart, and upon very careful analysis I discovered that:
