# Disney Mickey DT1350-C CRT RGB mod

This tutorial covers the RGB mod for the below models

The RGB mod for this CRT is the same as Disney Princess DT1350-P

# CRT safety

DANGER

You can die doing this! So read carefully! CRT TV is not a toy. Do not open a CRT TV. If you don't have any prior knowledge about handling high voltage devices, this guide is not for you. CRT TV contains high enough voltage (20,000+ V) and current to be deadly, even when it is turned off.

WARNING

This CRT has a weird wiring method where the AC cord goes through the bottom of the back cover. Also, this version of the Disney Princess CRT doesn't stand still without the back cover.

# Composite input

Composite input on this TV looks really good. While RGB definitely takes the quality up a notch, be careful not to make any un-unecesary modification to this CRT as these CRTs are becoming rare.

# Theory

Sometimes it is nice to know the theory behind the mod. I have put this on a separate page. This shows how the various resistor values are calculated.

# Calculating the RGB external resistor value

You can use this pre-calculated chart to find the resistor values needed for 4.7 kΩ inline resistors. You will notice 750Ω resistor value will work for this mod. I chose to use 680Ω as I had that in hand. But, anything in the range of 550Ω to 800Ω should work ok here.

# Performing the mod

Now that you roughly know what needs to be done, prepare for the mod. Place the board on a comfortable place. Make sure you are not putting pressure on the flyback or other components.

# STEP 1: Remove the following components

Remove the three 680 ohm, RGB resistors to ground. Measure and mark before you remove.

  • R102
  • R103
  • R104

# STEP 2: Connect RGBs, Blanking and Audio

Remove the resistors marked with the pink square boxes. Wire the R, G, B and blanking wires to the points marked as 'X' on the diagram above. The mod on the CRT is fairly straight forward and follows the standard mux mod.

It's almost like the chassis designers were expecting someone to RGB mod this in the future. There are pads easily available on the board to solder the wires.

# STEP 3: Build your mux board

Below mod uses the RGB mux board. This is optional, but will make your mod easier and stable. You can also create the circuit presented in the schematics above without the board. Please also checkout the precalculated resistor values.

TV Model 1350P RGB Mux Board Notes
RGB inline resistors 680Ω R1, R2, R3
RGB termination 75Ω R4, R5, R6
Audio LR shorted R7, R8 (1 kΩ resistor present on the board)
Blanking inline 4.7kΩ R9 (CRT internal 4.7kΩ resistor for 2.5V)
Blanking ground open R10 (CRT internal grounding resistor is used)
Diode 1N4148 R11
Csync 75Ω open R12 (75Ω terminated in the CRT)

While pressing the Volume down on the CRT, press 9. Only adjustment I had to make was the horizontal phase (shift).

WARNING

This tv has a weird wiring method where the AC cord goes through the bottom of the back cover. Also, this version of the Disney Princess CRT doesn't stand still without the back cover.
