 +**Note** There is a potentially better method mentioned on the forums ([[http://​midibox.org/​forums/​topic/​21498-connecting-mb-6582-pcbs-with-jst-xh/​|here]]) which uses JST headers on the baseboard and either right-angled JST headers on the CS or just normal right-angled SIL headers. Coupled with ready-made JST cables, this is a much simpler approach and allows the two boards to be separated easily. It is worth a look before going down the path mentioned below.
  
 This is a slightly difficult process, so I'll give as much advice as possible. This is a slightly difficult process, so I'll give as much advice as possible.

 +Here is a guide to soldering the wires to the LCD. I suggest "​rounding"​ the cable afterwards, it's easier to identify which wire goes to which pin when it's still a flat ribbon. Also, don't solder the wires INTO the holes, strip, tin and solder tinned ends flat against the pads.

 I've suggested **not** soldering R40-R55 until now. Now you can take a 220 Ohm resistor and insert it into one set of pads of R40-R55 and see how bright the LEDs are. For SmashTV LEDs, 1K will probably be best. If you are using some ultrabright or superbright LEDs, blue or white LEDs, etc. you may want to try 2K, 3K or higher resistors. **Keep in mind, what looks like a good brightness as a single LED might become too bright and too much glare when there are many lit at once. It is best to choose a resistor that makes the LEDs a little less bright than the brightest you can handle.** I've suggested **not** soldering R40-R55 until now.
