Disney M70 CRT RGB mod

This tutorial covers the RGB mod for the below models

  • Disney Winne the Pooh - DT1350-RWP (AUG 2005)

CRT safety


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.


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.


Plan of attack



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

Since this CRT didn't come with grounding resistors, I chose to use the same resistance value that was present in the inline circuit ~1 kohm. I will be trying with different resistance values in future.

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: Connect RGBs, Blanking and Audio

Since there are no components to remove from the board, we can get the wires connected to the board. The mod on the CRT is fairly straight forward.

STEP 2: 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.

Buy your RGB mux board

Getting into service menu

While pressing the Volume down on the CRT, press CH 1/2 then Display then CH 1/2 then Display on the remote to get into service mode (aka D Mode).


Once in D Mode, press 3 to enter adjustment menu. Here you can navigate using CH +/- and adjust using VOL +/- buttons.


To write values press CH 1/2 button on the remote
