    Neovo E-17DA monitor repair

    Nearly all (over 300) of our monitors are AG Neovo E-17DA models. Over time, we have identified two recurring faults with them:

    • Monitor doesn't power up (Problem: 1 bad solder joint)
    • Monitor displays image for half a second before disappearing (Problem: bad capacitors)


    Our problematic monitors were originally repaired under warranty, but now we have a large number that are no longer covered. Having nothing to lose, we set about attempting to repair these ourselves, saving us £130 per unit in the process.

    You can find a HOWTO guide (with photos) that I put together here: Neovo LCD repair - Bishop Barrington IT Support

    Hope that's useful to someone - enjoy.

    We have the 'Monitor doesn't power up' issue and were previously stockpiling 15+ out of warranty monitors with this fault.
    The fix you suggest works. This will save the school hundreds of pounds; thank you very much indeed.

    I love you.
    We've had so many of these die with these exact faults - Our own attempts at repair weren't that successful. Got a whole bunch of them in storage still so we'll give it a shot!
    I was getting quite annoyed with it to be honest, our stock may be 4/5 years old but tons have gone recently

    damn I only just put back together the monitor I had dismantled with the no power fault as I couldn't see anything wrong with the caps.

    FreeWill, DrCheese: We were in the exact same situation, and thought there must be a simple and cost-effective solution. Glad it's helped

    Ok dismantled it and coil joints looked perfect to the naked eye but resoldered them also re-did one extremely dry looking joint on a resistor and voila it works

    Shouldn't step 9 be Insert one of the screws on the inverter board.???

    Probably. I might have been thinking of the one that secures the metal bracket in place for the inverter, but screws into the logic one.

    @Webman

    This is a stab in the dark but do you know where i can get an inverter board for an AG Neovo monitor? I have been in contact with winston from Holland but for some reason he isnt answering my emails now.

    Thanks

    @timbo343:

    I have tried to gather this information for ourselves but unfortunately have only come up with this so far: AG Neovo E-17DA - Badcaps Forums

    You will probably have to register (not a bad idea) but this is as much as I can muster at this moment.

    P.S if you do find anything please post

    AG Neovo E-17DA LCD Monitor on eBay (end time 27-Jan-11 11:29:01 GMT)

    Has had a new inverter board fitted may be worth a message to the seller to see if he can source them?

    plexer: In one of bossman's posts about the Badcaps forum, it seems that the seller of that Ebay item is a member on the Badcaps forum that bossman has contact with
