So I did my 1st capkit, ordered from Arcadeshop.com

as a newbie I missed that two (actually three if you count C313)

caps were way wrong..


C303 and C308 instead of the 2.2uf @ 50v they sent 22uf @50v

I of course installed all the caps in the kit except C313 not noticing the error..

Then as has been seen in tons of my last posts

I get a weird Fold-Over at the top of the screen?

Everything else looked good and after a call to John Pruski, Tech Support at Wells Gardner Electronics

The course of action that I could do was to swap back in the original caps starting with C300's in video output..

So I swapped C311, C310 and when I get to C308 I notice that the new cap installed is a 22uf instead of the 2.2uf one.

I freak a little bit and swap back my original 2.2uf at both C308 and C303 which are both the wrong 22uf from the Arcadeshop capkit.

Guess what, after putting those back I get nothing from the monitor, no hiss, no picture, dead...

I'm a bit crushed as this morning I had a not perfect output with foldover that was corrected with the V-Damp, cutting about 1 1/2 inches from the top, but playable enough for an expo.

Now I have nothing and I don't know what to do or where to check. Sorry for the rant but I am mad at myself, mad at Arcadeshop, just bummed in general. It's my fault for not ordering from Bob Roberts.

Lesson Learned the very hard way.

Bummer. Yeah, Bob or Zanen would be the safer choices. I haven't ordered a cap kit in many years... I just order a bunch of caps so I can put them together myself. That way if there's a problem it's all my fault. :D
One thing I do (before any soldering) is lay all the caps out first and check them against what is installed in the chassis. That's saved me from making a couple stupid mistakes in the past.
 
The best thing to do is to check my site for the lists (which except for one that I need to correct seems to be 100% accurate). Then compare that to what they send. Higher voltage ratings are fine, but discrepancies in microfarad values should be verified before continuing.

I also buy my caps in bulk and make them as I go. I often find people have rebuilt them with the wrong value in certain spots, but the location isn't too sensitive and the monitor will still work, with maybe a different centering limit or something. That is why I keep the list up on the screen (or printed) for comparison checks while doing the kit...
 
define the "right way"? If it was not connected at all I would assume you would have a light show if it was close to anything metal. But as far as I know there IS only one way to install it. Pull back on cup, insert the metal spring tong into the tube so it grabs the inside of the glass let go of the cup, it's installed....
 
What would happen if my dumb newbie ass didn't put the anode cap in the right way, would the monitor appear to be dead?

I can't imagine how you would put that in wrong, it only goes one way. hah. If however you didn't put it in all the way.. I would expect that you would have some serious arcing going on.
 
Yeah it's in the right way, something in the chassis is toast.

Another collector in Boynton Beach is going to loan me a 19" from a bubble bobble that if it works will stay with the MC..

I guess I need to start asking around for someone how fixes monitor chassis..

Oh well!
 
Just a newbie mistake to not order from Bob Roberts, not get the proper soldering iron, solder, triple check te cap kit and overlook 22uf for a 2.2 which probably caused my fold over issue, then panic and start swapping old caps in a mad dash to fix the monitor while looking for bad solder points on the chassis thinking that I'll get lucky and magically fix it..

A dozen rookie mistakes and lessons learned the hard way.. But I'll be totally honest, I loved every minute of working on it. This hobby is electronic crack..
 
arcadeshop

i have orderd from arcadeshop on many occassions. ive never had one single issue with them.im sure if you contacted them they would fix the situation.that would be my suggestion before slamming them in a public forum. mistakes happen. any business that is AMERICAN owned deserves the opportunnity to make it right before being slammed. remember, you live in the same economy.
 
Arcadeshop.com

Peerless, respectfully I don't feel that my post was slamming them. I understand what it means to work for and have a stake in an American owned and operated small business.

I contacted Arcadeshop.com immediately via email as soon as I found the error, which was to late. Again in my posts I spelled out how many newbie mistakes I made in a row.

I emailed them on Wednesday with no response.
I called them yesterday before posting and she said that she would send out a new cap kit. Had I found the error before and had time, it would of been good. So many newbie mistakes.

But really they can't do much about the problem now. I'm lucky to have found someone local who has a replacement monitor.

It was a mistake to order a cap kit from them. In this instance in my opinion, I feel it was a mistake. The cap list sheet they sent was for an older version of the K4900 than I had, but they only have the one K4900 cap list.

Hindsight 20/20 I can look back and say that if I had better tools, ordered from Bob Roberts, triple checked my caps then I would not be here right now.

I don't think it's slamming to say in my opinion it's a mistake to order cap kits from Arcadeshop.com, it seems the public KLOV consensus is to either make it yourself or order from Bob Roberts..

I think that's fair and honest, but maybe I'm wrong.

Of course...

Now I do go back to my 1st post and I was freaking out pretty hardcore, maybe I freaked out a bit to much..

Add that to the list of newbie mistakes..

Hopefully I don't make many more this weekend.

Again thank you to everyone here for helping.
 
Mistakes happen. I once got a capkit from arcade shop with a few wrong caps in it... I called them and they quickly sent me the right caps! I've orded from them many times before that and many since! Between arcadeshop, Bob, Mike's, and everyone here, we have lots of options!
 
you're going to have a rough time of it if you boycott every supplier that makes a minor "mistake." bob roberts is great, but i've had a mistake or two from him in the past too... UH OHS.
 
If it worked before you swapped your original caps in, either:

- Those caps are dead
- You dun goofed reinstalling them

Either way, stay frosty, roll to your local electronics supplier, grab caps, and replace. You should be okay.

Whenever I recap a chassis, the very first thing I do is put 1-2 pieces of double-sided tape next to the cap listings, then stick every cap next to its position in the list. It lets you know right away if something is wrong with the kit, and makes it easy to find the cap you need instead of hunting it down in the middle of the job. You can use your own list if you prefer.

Monitors I haven't done a few times, I pull one cap at a time, making sure of the correct polarity. If it's a more common monitor I've done a few times before, like a K7000 or G07, I drop all the caps first, put the new ones in, and solder everything. It's faster, but you have to know the quirks, like the cap that's screened wrong on the G07.

Work done in haste is work you do over. Keep it methodical.

i understand your frustration, it does suck for things like this happen..just keep in mind that we are hobbying with some pretty old stuff here and the fact that there is anyone out there that we can get things from is a miracle in itself. also arcadeshop.com is a large supplier for many of us here in georgia.this allows us to maintain our hobby while supporting the local economy.these small operations are getting more rare each day and unless they took your money and you didnt get the product or they tell you to screw yourself,i think all else is easily resolved. they are good people. they love this hobby as well. they have to , they couldnt possibly be getting rich off of cap kits and t-moulding.so anyway, thanks for giving them the opportunity to fix it.please forgive me if i was a bit abrasive,im just a bit deffensive for my fellow americans trying to make it in this godawful mess we call an economy.hell, were all in this together.

paul400 in Spring hill does, and i was just in fort lauderdale @ ape last week, not on the list yet, but may be making it down that way next weekend. (not 100% sure yet, may be a meet at yeehaw junction machine transfer.
