ID-5001 LED Backlight Conversion
Version 3 with Linrose Super Brite White LED
The LED backlight conversion replaces the fluorescent lamp with LED strips of
equilavent brightness and greater reliability. The upgrade process
involves disabling the fluorescent circuit on the power supply board, removing
fluorescent lamp sockets, building the LED "board", and mounting a socket for a
2.1mm 12VDC power supply plug on the back of chassis.
The steps provide sufficient information for the experienced eletronics

* Prices may vary.
- Disconnect ID-5001 from the wall power.
- Remove main cover and lamp cover.
- Remove the main circuit and power supply boards.
- Cut the two traces that supply power to
the fluorescent lamp (see Figure 3).
- Remove the lamp cover plate.
- Remove fluorescent lamp and lamp sockets.
- Reinstall the power supply and main circuit boards (see note for step 1
LED Board (refer to Figures 2 and 3)
- Mount the 2.1 mm Power Jack Socket Female Panel Mount Connector to the back of the chassis near where the AC power cord enters.
Note: it may be easier to mount the connector prior to reinstalling the
power supply and main circuit boards.
- Prepare 1" by 10" rigid plastic backer.
- Cut both LED strips to about 10" (cut strip only where indicated by the
markings on the strip itself).
- Remove LED strip backing to expose the adhesive. Affix to the
- Prepare 10" red and black leads. Remove 1/4" insulation from each
- Solder one end of the red 12" lead to the positive (+) solder point on
one end of the first LED strip.
- Solder one end of the black 12" lead to the negative (-) solder point on
one end of the first LED strip.
- Prepare 2" red and black leads. Remove 1/4" insulation from each
- Solder one end of the 2" red lead to the positive (+) solder point on
one end of the second LED strip. Solder the other end of 2" red lead
to the same solder point in step 6.
- Solder one end of the 2" black lead to the negative (-) solder point on
one end of the second LED strip. Solder the other end of 2" black lead
to the same solder point in step 7.
- Apply 1" pieces of double-sided foam tape to both ends of the back the
- Affix the plastic backer to the inside the light chamber in the previous
location of the fluorescent bulb. Route the red
and black leads through the gap between the sides of the light chamber to
the back of the chassis where the female 2.1 mm adpater is mounted and
solder the leads.
- Replace the light cover.
- Apply 12VDC to verify light operation.
- Replace chassis cover.
- Apply AC power.
