Hanabi Hyakki reel light replacement

[Ikaria]

Started this new thread for anyone with bad LED reel lights in their Eleco pachislo machine. I know it's been covered, but what can I say?

For more info, you can read up here => http://www.pachitalk.com/forums/pach...ds-faulty.html and follow the links.

LED's obtained from => Discrete LEDs - Quickar Electronics Inc

9 items from the bottom of the page are Piranha white LED's. You need 18 of them per machine (6 per reel). The item # is whpir (White Piranha 1200 mcd Typical @ 100 degree 20ma). Currently $.95 ea.

Additional Items you will need. (based on what I used, your milage may vary). From Radio Shack.
- 30w soldering iron kit (incl. iron, stand, solder, solder tool, and heat sink)
- *optional* solder stand w/ sponge (makes things much easier than chasing your iron around)
- desoldering braid

Also need a pair of wire snips to clip off resistors. And isopropyl alcohol to clean the residue off the circuit board after desoldering.

This is an easy project provided you have steady hands. This was my first time desoldering, and I had no trouble. Elapsed time approx. 1 hr.

Disassemble your reels and take the circuit board out. I did mine one at a time, and marked the orientation of the reel motor to the housing with a sharpie.

Before starting the desoldering process, cut off resistors R2, R4, & R6 with the snips.

To remove the old LED's, spool out a length of the desoldering braid, and place it on the LED prong to be desoldered , heat up the braid, and the solder with the iron. The braid will wick up the hot solder leaving a solder free joint. After all 6 legs of the original LED are solder free, use the solder tool (from the kit), and pry the LED off the board. Don't force it!!! If it appears to be stuck, recheck for any solder you missed and try again. You can also snip off the LED legs and dsolder them , but I found it easier to desolder the 6 legs and pry the whole thing out.

Before installing the new LED's, clean the residue off the board with the alcohol.

Install the new LED's as oriented in the pictures, and solder them in.

Install the circuit board in the reel assembly, and re-install the reel.

Enjoy playing your newly repaired pachi with the satisfaction you fixed it yourself!
