i have a ctc195 here i think the congergence power supply is dead i have another ctc195 but the power suppy is the different one are they interchangable?one has the stk ic the other one has the smmaller ic.

as far as i can tell there is only 2 different power supplies and they are interchangable but i cant find the part# for model#p52929 to make sure it does have stk730-130 ic on it and so does rca#239124 and a lot of dealers say its not available so use rca#250686
