    Acoustic Solutions LCDW22HDF - Vestel 17IPS02-2 Blowing Fuses

    Hi guys

    I wondered if any of you have had any experience with a Vestel 17IPS02-2 PSU??

    It keeps blowing fuses and I'd really appreciate any suggestions on how to track the fault down.
    I haven't attached any images because google shows plenty of this model and even has a schematic.

    I'd appreciate any suggestions on where to start and what to test.
    I'd also love to know more about the "light bulb trick"

    Am I correct in assuming that instead of fitting fuses to keep blowing, I can attach a light bulb to the fuse holder and not risk any of the other components on the board?

    Thanks in advance

      Close -1 (not -2) schematic


      Check for shorts:
      Check D800-D803
      Check R805
      Check IC800 pin 1-2
      Check C813 (if IC800 shows short, remove from board and test each separately)

      Yes, the light bulb typically goes in place of the fuse. When there is a short the light bulb will glow. When there is no short it will be off or flicker now and then. The TV will probably not start with the lightbulb in series.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

          Hi Tom

          Thanks for the reply.

          I've found 2 of the diodes to be short so I've ordered a pack and will replace the lot.
          I've also ordered a STR-W623 just in case. I haven't had it out to test it yet but I thought I might as well order one now and then I've got it anyway.

          Just the resistor to test now but I'm pretty sure I can find one on a scrap board if it needs it.

          I'll update further once the parts arrive in a few days

          Cheers

              Hi guys.
              I forgot to update this thread

              In the end, I found 2 or 3 of the diodes to be faulty. D800-D803
              I replaced these and the TV worked perfectly.... in fact, it still works perfectly now over a year later.

              I did send Tom66 a PM thanking him for his help but I'll do it again in here.
              Thanks for your help Tom

                  How an incandescent light and a ESR meter ** friend**have a machine blowing fuses
                  by sam_sam_sam
                  About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well

                  Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for

                  Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer...

                  HH Scott Model A510 Stereo Integrated Amplifier/ Graphic EQ - Blowing fuses in the LEFT speaker channel only. Any Help???
                  by Sik_6ty_Sixx
                  So like the title says, I have an old Stereo Receiver/Amplifier that I picked up from the goodwill, it's a HH Scott Model A510. When I first got it home it had zero output. Opened it up, notice the fuses are missing. Pop in 2 new fuses (AGC4A 250V) and try again, within 5 seconds the L channel fuse POP! I don't see any visible indications of damage or arc burns on the PCB, no popped resistors or diodes, no burnt traces or blown out caps. So I decide to just try another new fuse, POP. Swapped around my R and L speaker wires, and checked the integrity of all wires and connections. Everything looks...

                  1970 Metal Lathe Control Circuit blowing fuses on the 120 volt section failing meager test below 60 mega ohms
                  by sam_sam_sam
                  I was working on this machine yesterday and I now going to use an incandescent lights instead of a fuses to figure out what the issue is with it blowing control voltage rail but this not the only issue the coolant pump failed the meager test as well as the main motor as well this motor has 12 motor wire leads instead of the normal 9 wires

                  This metal lathe has a weird motor setup it has a soft start motor with a “Y” and a delta type of motor winding setup and it is not done in the motor pucker head enclosure it is with four different contactors wired in a configuration I have not...

                  Gemsound PAX-105 Audio Amp blowing fuses
                  by mon2
                  Hi. New to this side of the forum.

                  Have an audio amp (Gemsound PXA-105) that keeps blowing the 3A fuses upon power up. Owner stated that the amp was on when he plugged in the input (mixer board) and that started this chaos.

                  Would a schematic be available? Advice on what to check? Power supply / output amp transistors? Do see the power on green led turn on for a brief moment before the fuse blows.

                  Thanks.
