Eiki LC-XA20 Ballast bypass not working
I am trying to bypass the ballast in this projector I got for free so I can LED mod it. I have found the wires going from the ballast to the main board. I found the pin for the transmit optocoupler, and I shorted it to ground. Before I did this, the fan would ramp up and down 3 times over the span of a minute and then flash the power led. After I did this mod, it now goes green for a few seconds then cuts to the flashing red. If I shine a light, I can see the eiki boot logo until it realizes that there is no lamp. I found the thermistor and I heated it and saw the resistance dropped to 0 ohms, so I tried shorting the pins for it but it had no effect.
