There was a similar post I saw with a 25" model. I never saw if he successfully got it working but this is my understanding.
I cut or don't cut the RGB output traces coming from the micro.
I then solder my RGB signal into the RGB input of the jungle chip terminating with a 75Ω resistor to ground for each. (Dividing the voltage)(The input going in-between the resistors)
Then I cut or don't cut the trace from the blanking pin on the micro going to the Jungle IC.
I then I wire a 3.3V or 5V source to the blanking pin on the jungle chip.
After that I wire the Sync output to the composite input of the TV.
Then I wire the ground to ground.
I have modded a TV successfully before but I ended up wiring my RGB Jamma 15Khz to the output side of the chip in series with 100Ω resistors.
Any advice is welcome and very much needed.
