    Distorted LG 32LH25R-TA

    Hi Guys,

    would like your input on this LG TV.

    I've not checked the boards or voltages yet as I've not got the TV on my bench yet. Just contemplating if I should accecpt this TV for repair.

    What would be the most likely fault? If the TCON board is at fault is it accessible? Could there be a fault with the power supply or main board that would cause this defect?

    I can't seem to find the service manual for this LG model.

    Thanks in advance.

          Panasonic SA-MAX770PU SMPSU board fault....
          by Rictech
          Hello everyone. 😀

          As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
          Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

          Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
          This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
          There are no devices that have exploded or otherwise show signs...

          Samsung QN75Q6FNA backlight no display, red LED blink 2x, fault in panel
          by howardc64
          • Prior owner tried a replacement main board. No difference.
          • Samsung 2x red blinking standby LED = panel fault
          • Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
          • Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
          • Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

          ESR meter came to the rescue again today with a PLC I/O card fault
          by sam_sam_sam
          I have been having a fun time at work with two pieces of equipment that had shorted components or shorted component cables to machine frame
          I would check what my multi meter was telling me about how many ohms I getting with the multi meter was telling versus the ESR was telling me about weather or not it really was a short to machine ground or not

          One note at first we thought that it might be a bad I/O card or a malfunction PLC including me as well but I thought I would try and see if removing the I/O cables would make a difference or not and this time it did make a difference...

          Yamaha MOX8 boot freeze and distorted sound
          by maleksa
          My Yamaha MOX8 synthesizer recently developed two issues.

          Firstly, after booting up, it operates as normal. However, after about 5 minutes, the sound starts to get distorted (broken up screeching sound) almost like putting it through a guitar distortion pedal. After a while, the distorted sounds will go away for a while and comes back. At times, the synthesizer will also freeze I need to power off and on again.

          Secondly, when powering off and on again, there will be times where the synthesizer will freeze during the boot sequence (freezes at the MOX8 Opening Screen),...

          Strange fault on Lenovo ThinkPad E14 Gen. 2
          by cazi1001
          Hello,
          I have a strange fault with a Lenovo ThinkPad E14 G2 (Board No. NM-D011 Rev. 1.0).

          The first Problem, which I fixed already, was a dead TPS65944AD (USB Type-C) controller. After I fixed this fault, all functions working fine and the notebook run very well with the charger and battery.
          On the next day, I tied to start the notebook with the battery, but nothing happened. I started with the charger and on windows, I saw, that the battery was empty. And this was nearly impossible, because the battery was charged. I disconnected the battery and found out, that the board...
