    Got into this hobby a few months ago. Have never handled a soldering iron etc.

    Well, the bottom sigments have been out on flash. I narrowed it down to the resistors on the master display. (thanks Clay). One of those resistors looked burned and didn't test anything. I said what the hell, i'll try to remove it and replace.

    Went to the shack, bought the .022 solder as told, the wick, and the resistors. Took me all of 15 mins to pull the old one, clean up the old solder via the wick, and replace with the new. And it works.

    Total confidence builder. Just had to share!

    WooHoo - Congrats~!~! It's a great feeling when you bring an old pin back to life.

    Good Job!...You'll be replacing 40 pin PIAs before you know it

    The feeling is great. And I'm learning so much. I'm a lawyer in my other life so this is all completely foreign to me.

    It was hard keeping my hand still while doing this. I was a tad nervous for some reason.

    Lawyer....Good to know where to send my legal questions

    I do think I owe you Robert. Anytime!

    I was hoping when I saw this thread that it was Blackbeard that was posting it. Good job and congrats!

    It's fun to fix stuff. Good job Blackbeard!

    #9 9 years ago

    Hey way to go Blackbeard.

    It is a good feeling isn't it.

    I would suggest you pick up a solder sucker at RS as well. Works much better than the braid.

    The guy in that video sounds like Clive from coin op cauldron.

    #15 9 years ago

    Yeah let me see you flick your WMS MPU board

    Was thinking the same.

    That is Martin from pinbits in the video.

    Great job!

    BIG Congrats Blackbeard,I was also hoping this was your post,as I was sure you could do it,when YOU were ready.
    You know we were just teasing/encouraging you a couple weeks ago.
    Did you end up getting a gun style soldering iron ? or did that 40 Watt pencil soldering iron do the trick?
    Good going man,pretty satisfying huh----------------Kirk

    #19 9 years ago

    Did it with my 40 watt iron. The part I found most difficult was removing the burnt resistor. Everytime I'd heat up the back side, id drop the iron and grab my pliers to grab the resistor and pull, but by that time it would have cooled off. Those helping hand clips must be pretty helpful.

    very nice Blackbeard

    That is why you have 2 hands Set the board on the bench, or use a vise.

    I use one of these.. if you find yourself doing a lot of board work, you may want one. I have an expansion bar so I can put a board as big as a WPC power driver board in it. The base is weighted so it won't tip over.

    That's a nice vice! What's the model number?

    #23 9 years ago

    Wow, I have never seen vises like that. I did a quick google, and found some products by Panavise.

    This one looks pretty amazing, but only goes 12" wide. I'm sure there are other models that might be more appropriate.

    It's much easier and I think better to cut the old parts off the board first. Then clean the holes up and your ready for your new parts.

    I thought about that Jalpert, but I had some lousy wire cutters that couldn't get into the resistor well enough.

    I think this weekend I'll reflow the solder joints on my gorgar's cpu as those displays are acting up too.. and i think it's cracked solder joints.

    Im feeling brave.

    #26 9 years ago

    Congrats! I still cringe a bit at the board work but still go for it anyways. Ive only ruined one and a few displays but it really does get easier the more you do. Havent smoked one lately so Im probably due. Its definitely gratifying to trouble shoot one and get it fixed. Kick a$$ vise John!

    #27 9 years ago

    Way to go blackbeard! that is my next step and I am nervous as hell too, great to hear that with no experience you were successful, congrats!

    #28 9 years ago

    The new issue i'm having on gorgar is the 1st digit being strange on the first player display and also player 3 (i believe..).

    When I jiggle the connectors on the top of the cpu, the problem disappears and then reappears. I'm guessing either cracked joints or the pins need recrimping.

    #29 9 years ago

    Congrats! Cool feeling when it works, isn't it? My first board repair was a Stern Memory Lane that battery acid had wiped out darn near a quarter of the driver board. Nothing like trial by fire! If you make a habit of board work, I'd suggest investing in a nice temp control solder station. I know a lot of people recommend a de-solder station too, but I've honestly gotten along just fine with a bulb sucker. It's kind of fun actually...

    Congrats, If you want to practice more get some cheap PCB from Radio Shack or tear apart some old electronics and play with the board.
