    Manson HCS-3402 Failure

    G'day all from a first time poster.

    I've got a Manson HCS-3402 here that has been playing up, and then today failed.

    On start up it used to go through all the self tests OK, run for 30 seconds then power down. Yesterday, it ran through the self tests OK, then displayed ERR on the front panel.

    Today I powered it up, and got nothing. I tried again in preset mode, and it powered up, ran for about 60 seconds, then vented smoke. On the primary side, U2, Pin 4 looks more like a failed fusible link with D5 also looking quite sad. Mains fuse (as expected) also blown.

    Before I get too carried away, are the schematics readily available for this model? I did read through an earlier thread on the 32xx series and grabbed info from there, but quite a bit of difference between the models. I believe these are the same as the Peaktech 1575.

    Hoping that there is a chance of resurrecting this!

    Cheers.

      You can get some here

      https://www.ebay.com/sch/i.html?_nkw...&ul_noapp=true


      https://www.jotrin.com/product/parts/TYN275PN

      They say that they take PayPal
      I would not recommend buying from them if they do not take PayPal

      That just me

      I would recommend that you check for shorts near and around that chip seeing how the pin burn off the chip

      Could you please post a wider view of the area around that chip thanks

      Here is the data sheet for this device

        Power supply Manson NTP-5561 (5661) LCD controller dead - PIC18F87K90 HEX dump required
        by Andreas_de
        Hello!

        i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
        Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.

        Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?

        Carrier HK50AA063 display controller common failure help
        by ctroxtell
        I've got a control display for a Carrier chiller that I'm trying to understand what the common failure with these boards are. This is the board in question https://www.supplyhouse.com/Carrier-...arquee-Display all of them seem to develop a failure with the up and down arrow buttons on the right side of the display, the esc and enter keys I've never seen fail. Once these boards are plugged in they run 24/7, you used to have to press extremely hard with the end of the blunt screwdriver and you could still get the arrows to work but now it has completely stopped working. The button...

        Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
        by howardc64
        Problem

        Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video



        Model & Board Pics



        Conflicting Spec

        Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

        Mitsubishi CNC switching power supply board dead / relay board bad diode failure
        by sam_sam_sam
        I was working on this CNC machine today found no keyboard functioning no control relay powering on
        The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board

        Found shorted diodes on main controller relays there are 3 of them that...
