    I melted off the resistor while trying to repair the trace of R4P4...

    I need the Ohms of that resistor that was in place...

    Any help would be appreciated...

    I agree, trace repair is much more difficult than the original job.
    are u asking if someone will do it for you? If so, I can help you out :smile:

    If u look closely using a magnifying glass u can see the traces . Then just removed the solder mask and carefully pretin and solder some kynar directly to the traces .

    R4P9 should be easy to fix, as it just has one via/trace under the digit '9'
    But you'll need a fine tip and a good soldering station, not a cheap soldering iron.
    [doublepost=1535036256][/doublepost]Another note is it will be easier and safe to work on C5R11 on corona, because it's an end point on Corona, means you don't have to repair it even you damaged the pad

    Sure it is repairable. But with current your soldering skills - no dice.



    yellow marked is surface damage, red dot mark is for revealed copper wire (small dot) possibly multilevel pcb connection.

    yellow dot represents missing pad, also on the red mark should be a pad too.

    Could be more, picture is a bit blurry for fine traces.

    It would be a $$$ to send it to repair guy.

    Since it's your board, do what you want.

    Thank you for highlighting the trace...

    I assume I would connect the copper pad and try and scratch off and reveal some copper for the other trace ending?

    Honestly, you dont have the skills and tools for soldering properly. Trace repair is much harder.i'd stop there and give it to other people who knows what they are doing .

    I honestly don't care about ruining the board... It's experience for myself and I enjoy doing things like this... I was using too big of a solder iron and I didn't have any smaller tips...

    I am asking for help and you all keep sending me to waste money by sending it to another person...

    If I wanted to send it for service I wouldn't be posting to these forums...

    There's balance in this, DIY , learn and gain experience. If you are not ready for the first step , you sure dont want to try the 100th step. Yes sending to other is wasting money to you, but imo you'll keep waste your time. You wont able to fix this on your own.

    Well, I am prepared, but if no one wants to help, then it's all cool... I'll just trial and error until I get it working again...

    Thanks for the advice...
