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.

  • Screen Size: 29"

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. Taking out the chassis is fairly straight forward on this CRT. There are few wires that needs to be disconnected.

  1. Degauss wire
  2. Power wire
  3. Ground wire attached to the neck board
  4. Yoke deflection coil wire
  5. Anode wire (this is the one with the rubber cap)
  6. Left and right audio wires

Please remember that wires 1-5 are critical for the CRT to function and should not be omitted. Having any of these wires disconnected while powering up can damage the board and can have adverse effects.

Wanted to share a quick picture guide of this model with a mux mod since none are available in Sunthar's guides for the G3F Sony chassis. Mux mod kit purchased from Sunthar for a nice and tidy install.

Quality is pretty decent after the mod. I might attempt a G1 mod as the picture is kind of blurry and nothing I tried helped. This is the sharpest I could get it after calibration and focus adjustment.

I dropped and broke this panel during the mod. Also the hole for the scart connector was in a bad spot. The rear shell blocks half of it after putting it back together. Did not realize this while I was cutting it out. There's a bunch of stuff on the back of that panel so finding a good spot will be tough. I decided to 3d scan and create a replacement back panel (if you're wondering what all these stickers are for, they are markers for the 3d scanner).
KV-F29MF1 - The 3d print turned out OK and did the job.
