    NAD CD/DVD Player T-513 Problem !!

    Hello,

    I have a NAD T-513 that always display DISC Err, no matter what kind of CD I use.

    I change the optical laser pickup, it was only 20$, I had nothing to lose, but it did not solve the problem !

    My question is:

    On a good working CD player, is the RPM always constant, because on mine, it goes up then down, up then down repeatedly ???

    I check the VCC pins of the Motor Drive IC (LA6560) and +8V is present. But one thing I notice, this IC gets hot really fast ???

    Do you think LA6560 is bad or the spindle motor ??

    Thank you !

      by sbt123
      hi there,im having a look at repairing a wood lathe for my dad,(charnwood w821)the problem is when turning up the variable speed control,the motor starts to stop and start by itself,if i continue to turn up the speed it will trip the mcb in the consumer unit,there is also a slight smell of burning from the speed controll box.,Another strange symptom is the lathe can be unplugged from the mains after switching it off and the motor will spin a couple of times by itself,so far ive put a new speed controll potentiometer on and new motor brushes,ive also tested the motor windings and everything looks...

      Help troubleshooting an audio problem with an RCA SGT-250 CED Player
      by samson7point1@yahoo.com
      The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

      The player processes the audio signal using two different reference frequencies. The "R"...

      Problem with LG Plasma 60PM6700 - Random power downs
      by theone111
      I have an LG Plasma TV 60PM6700 for the past ~12 years.

      In the last ~3-4 months I have been having some issues.
      1. Problem: It started with random picture disappearing (sound still worked).
        Frequency: Happened about once a week.
        Solution: Had to turn off TV wait a few seconds before turning it on again.
      2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
        Frequency: Happened about once a week.
        Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
      3. Problem: TV shuts down

      Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
      by Zeonalbasta
      i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
      The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...
