    How long does it take to repair one?

    hakko: Just a re-solder: 15 minutes. Full capacitor replacement: 40-50 minutes.

    Those times are just for me - it depends on how comfortable people are with soldering, taking things apart etc. It also takes time to gather & set out tools and put them away again afterwards, so I wait until I have a morning or afternoon in order to do 3-4 of them at a time. The first time you do it will probably take a little longer to do.

    I have just put 2 and 2 together and emailed Sabre via the ebay site. Fingers crossed

    This is a great post, wish I would have found it earlier.

    Webman - This yellow board with no traces on top, is this a new board they replace when you send them in under warranty? OR Do all your E17-DAs have this board?

    I ask because my E-17A (analog only) has a different board, although it still uses the same 12v 4amp DC power supply, and the long rainbow connector looks the same. Picture and Schematic attached. Curious about the 3 pin Red, Brown, Black connector on your board.

    The pinout of the longer rainbow is:
    Pin1 - BLACK - +5vDC for Audio
    Pin2 - BROWN - GND / Audio (although pins 2, 3, 4 are tied together)
    Pin3 - RED - GND
    Pin4 - ORANGE - GND
    Pin5 - YELLOW - Brightness
    Pin6 - GREEN - Enable (1.5v-3.3v=backlight ON)
    Pin7 - CYAN - +5vDC for Mainboard
    Pin8 - DRK/BLUE - +5vDC for CPU
    Pin9 - N/C - Direct connect to +12v power supply

    On the BadCaps website, it appears he using +12v, GND, and Enable for the generic inverter.

    As a final note, looks like I'll be trying the generic inverter. My capacitors on the board seemed fine, so I thought it was the power supply. I bought a 12v 5amp replacement unit. I know it was 1amp higher rated, but figured the monitor would only pull what it needed. It did. Enough to blow U920 and U960, also cracked diodes D980 and D981 then burned up the new 12v 5amp power supply as it filled the room with smoked component incense. As in most of my other bad electronic experiences, the fuse (F901) didn't save anything!

    codecharmer: I can't be 100% sure what they do when sent away for repair; but it does seem that the problem is only with the yellow board - but yes, all of our E-17 monitors have that same one (bar a few very minor variations in identification marks).

    Sorry to hear about your fried board Usually, using a power supply rated for a higher current shouldn't be a problem, but in this case it was - maybe pointing towards bad protection due to failing components.

    Hi all the reason i had to use a generic inverter was that the tracks on the rear of the board were trashed from an exploding part see pic
    Also had problems getting a new board but the unit still has all menus and controls
    If anybody needs more info please do ask

    Just for info - Rocate is where we get our inverters from. Andy is the guy to talk to.
