RGB Modding KV-PG14P40

Post by odessa93 »

I am a completely newbie and know nothing about RGB modding my CRT. Though, I have heard about it everywhere. I have found a service manual for my particular TV. [https://data2.manualslib.com/pdf3/71/70 ... a5a6513b2c]

The schematic is on Page 24 of 43.

I'm afraid that mine have "hot chassis", and the buttons seems to be metal plated plastic, and I fear getting electrocuted even just by turning on via Power button. Singapore uses the same mains as UK, 3pins. My TV however is not using a kettle lead but is using 2 pins without true Earth grounding instead.

Is the RGB Mod doable on my TV?

It's moddable and about as easy as it gets. BG-2T chassis.

The TV has a text port CN001 that can accept RGB and blanking, the jungle has unused RGB port.

Remove R330, R331 and R332.

75 ohm terminated RGB into CN001 RGB pins

For blanking take 5V from Pin 5 of 5V regulator IC002 into a switch, then into a 1000 ohm resistor and into BLK pin of CN001.
