Had a 51" rca rear projection donated to myself. While off and power button pressed there was a clicking noise from the front of the unit. Rear cover was removed and it could be observed that the hv splitter had a crack in the casing and the power was arcing out of the splitter. I purchased a $72 dollar hv splitter, i read that the $20-$30 dollar one would break within a year, and the unit powered up no problems.
