# Kortek CRT monitors used on Pump It Up
|
||||
|
||||
## Monitor capacitor repair kit for Kortek KT-2114, KT-2914 and KT-3414 series color monitors
|
||||
|
||||
The following instructions are transcribed from a printout included in the repair kit from
|
||||
www.arcadesparepartsandrepair.com to replace capacitors on the aforementioned boards. You can order
|
||||
the full kit including these instructions at
|
||||
[www.arcadesparepartsandrepair.com](https://www.arcadepartsandrepair.com/store/components/capacitors/kortek-kt-2914-kt-2114-kt-3414-series-monitor-cap-kit-105c-nichicon/).
|
||||
|
||||
Note that the kit does not include the
|
||||
[filter capacitor C114 220 uF @400V](https://www.arcadepartsandrepair.com/store/components/capacitors/snap-in-capacitor/220uf-400v-nichicon-105c-b-filter-capacitor/)
|
||||
and needs to be ordered separately.
|
||||
|
||||
### Instructions - transcribed
|
||||
|
||||
Our kits are designed for alll models within the series so there may be caps in this kit your
|
||||
specific model doesn't require, and if you have locations that never had caps installed then please
|
||||
research it or ask before populating the locations because your model probably doesn't use them.
|
||||
|
||||
**The following parts are included with this kit:**
|
||||
|
||||
* 9x 1 uF @ 50V
|
||||
* 3x 1 uF @ 100V BP
|
||||
* 1x 47 uF @ 250V
|
||||
* 5x 4.7 uF @ 50V
|
||||
* 2x 47 uF @ 50V
|
||||
* 6x 220 uF @ 50V
|
||||
* 1x 3.3 uF @ 50V
|
||||
* 6x 10 uF @ 50V
|
||||
* 3x 33 uF @ 50V
|
||||
* 1x 100 uF @ 50V
|
||||
* 3x 3.3 uF @ 50V BP
|
||||
* 2x 1000 uF @ 25V
|
||||
* 1x 22 uF @ 50V
|
||||
* 2x 10 uF @ 250V
|
||||
* 1x 100 uF @ 250V
|
||||
* 2x 47 uF @ 350V
|
||||
* 7x 470 uF @ 35V
|
||||
* 1x 100 uF @ 100V
|
||||
|
||||
Be sure to install all of the parts on the monitor even though many of the original parts seem to be
|
||||
working fine. Age, humidity and temperature will cause the value of electrolytic capacitors to
|
||||
change. Installing all of the parts will assure many more years of trouble-free service.
|
||||
|
||||
Each capacitor is polarized and should only be inserted in one direction. Be sure to watch the
|
||||
markings for polarity on each capacitor. On the top side of the monitor board where each capacitor
|
||||
is lcoated can have a positive sign (+)./ Insert the longer lead of each capacitor into the hole
|
||||
marked positive (+).
|
||||
|
||||
Bi-Polar (BP) or Non-Polar (NP) capacitors have no specified polarity and are (Non-Polarized) and
|
||||
can be installed in either direction. Don't ever install a polirzed cap in a non-polarized cap
|
||||
location because a polarized cap can only handle current flow in ONE direction where a non-polarized
|
||||
cap can handle current flow in BOTH directions.
|
||||
|
||||
**Make sure the game is unplugged and monitor discharged before installing the following parts at
|
||||
your own risk:**

|
||||
|
||||
A good practice is to always remove old solder from all input headers and reflow new solder on them
|
||||
to eliminate cold solder joints. Make sure to do this with a connector on the pins otherwise when
|
||||
you heat them to remove the old solder the pins may drop out of the PCB and also the connector will
|
||||
keep the pins straight.
|
||||
|
||||
**Be sure to double check your work before turning on the power.**
|
||||
|
||||
**NOTE:** ON ALL CAPACITORS, YOU MAY USE A HIGHER VOLTAGE, BUT NEVER USE A LOWER VOLTAGE. OUR KITS
|
||||
MAY INCLUDE HIGHER VOLTAGE CAPACITORS!

||||
### Additional notes
|
||||
|
||||
#### Filter cap
|
||||
|
||||
C114 - 220 uF @ 400V
|
||||
|
||||
#### Unused caps on In The Groove KT-3414DF
|
||||
|
||||
The following caps are not populated:

|
||||
* C139
|
||||
* C209
|
||||
* C305

||||
Do not populate them as they are not required.
|
||||
|
||||
#### Swapped out caps to incrase picture brightness (?)
|
||||
|
||||
* C711 swapped with 10 uF @ 350 V instead of 47 uF @ 350 V
|
||||
* C603 swapped with 10 uF @ 50 V instead of 22 uf @ 50 V
