CRT safety
Caution
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.

RGB mux diagram
Performing the mod
STEP 1: Remove the following components
Remove the three 680 ohm, RGB resistors to ground
- R102 (680Ω)
- R103 (680Ω)
- R104 (680Ω)
STEP 2: Connect RGBs, Blanking and Audio
STEP 3: Build your mux circuit
This 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 mux calculator to play with your own values.
| Component | Value |
|---|---|
| RGB/OSD inline resistor (chassis) | 4.7kΩ |
| Removed RGB/OSD resistor (chassis) | 680Ω |
| RGB inline diode method (chassis) | No |
| 0.1μF caps replaced (chassis) | No |
| RGB termination (R1, R2, R3) | 75Ω |
| RGB inline (R4, R5, R6) | 680Ω |
| Audio LR (R7, R8) | 1kΩ |
| Diode (R9) | 1N4148 |
| Blanking Ground Resistor (R10) | open |
| Blanking Resistor (R11) | 4.7kΩ |
STEP 4: Attach the female SCART connector to TV
Creating a SCART cutout and mounting it is an art. I have a dedicated section for it.
How to create and mount a SCART female plug?
