Went and replaced the control module assembly (A/V inputs on back of tv) turned the tv on and the cooling fan acts as if the polarity is backwards or short in the system. the fan doesnt spin just ticks with the alternating current for the wall outlet it seems. i've retraced all lines/connections and all appear correct.
if let on for a few minutes the speakers will tick after the set warms up and repeat in a cycle fan..speakers...

any and all ideas/help would be greatly appreciated

those fans should be DC, so there's no reason they should be ticking 60 times per second.

I suspect a power supply problem.
What are the voltages at the fan input?
