    SMEG induction cooker error EA on both left hand side cooktops

    Hi all,

    I have a SMEG cooktop with a EGO 72.08041.002 power board. The two left hand side cooktops started to slowly fail, sometimes stopping with an EA error (Power board failure according to the manual) after a couple minutes boiling some water and eventually they completely failed and now get an EA error on both of them at all times. Visual inspection of the board went over ok, I checked the IGBT's and rectifiers and they seem fine, what should I look at next as this is the first time I'm fixing an induction cooker, I'm suspecting capacitors in this case, Which ones should I look at? Is there any way I can check them in circuit?

    Thank you in advance,

      A bit of an update:

      I forgot to mention that those 2 input fuses also measure ok, no indications of a short anywhere. I also desoldered and measured both of the large film caps next to the fuses and they measure good with a multimeter right around their rated 4.7uf.
      I also just noticed those 2 white relays which connect the respective live wires, could one of them for some reason not be triggering or maybe damaged? Would it damage the transistor that triggers them If it feed 12v into their coils to test them?

          Hi. Have you been able to solve the issue?
          I have the same exact problem with my SMEG Induction cooker.

          Thank you.

              Help with parkside induction cooker controller IC.
              by tibd
              Hello.
              I am troubleshooting a parkside induction cooker. The bord had a microcontroller ic with marking IH001 (dip24) which i think is faulty. Any ideas what this IC is, to purchase internationally? Otherwise there is a VIPer12a which seems working fine. No other defective components were found.
              Best regards.

              BENQ GC2870 Floodlight effect from left hand edge of screen
              by Briesmith
              I have attached an image of the screen showing the problem which is that I see a sort of floodlight effect shining on the screen from the upper top left edge. I think the image shows the defect better than I could describe it but I would be happy to add any further detail if that would help anyone trying to help me.

              If you have seen this problem before or just know what it is from experience/knowledge etc I would be very grateful if you could pass on whatever it is I can do to fix it.

              Many thanks

              Vizio M60-C3 Left Edge problem
              by Pinky Deepak
              I have a M60-C3 where the left edge has started showing issues as seen in the picture attached. Along with this, I also noticed some darkening on the left half of the screen which went away after I left the TV unplugged. i initially thought it was the led backlight that was wearing out but looks like something to do w the TCONN board. I searched this forum but couldn't find anyone else seeing this issue. most of them were LH/RH completely gone. any insights or guidance is appreciated.

              Here's a video of both the issues: https://youtu.be/hMqc760nB3o

              Induction hob PCB VESTEL 20fr25 from cooker Rangemaster propl60eibl help needed.
              by mariukonie
              Hi. Could anyone with knowledge advise if this pcb in photos can be repaired? I'm willing to spend time and money on it to gain experience however I searched net for schematics and couldn't find so it's impossible to know what are some of burnt components. I can't find any second hand replacement board and new one is out of my budget and it exceeds value of cooker. I'm new to this forum but have had few successful pcb repairs of tv's and cooker pcbs and also made few working circuits for fun. Any help appreciated. Regards....

              Panasonic Tx-40cx400b top left half screen not displaying correct
              by armoured_smiler
              Hi,

              Trying to work out if this is TFT problem or TCon issue.
              The TV powers up but the top half of the screen, from the right it is OK, but as you look across to the left halfway across it starts get duller and duller until it is very dark on the lefthand side, currently I trying to clean the remote as it seems to have something film wise on the pads stopping it from registering buttons pressed.

              Also when changing the screen size of Windows PC display to say to a smaller pixel sizewindow, the original window displayin the top left stays/takes a few seconds to disappear?...
