Question about 23.5V in the set. How important is this? The reason I ask is I tested the regulator and it seemed fine. However, what I noted was the installed regulator is 121-808 and the sheet attached inside the set has it as being 121-966. In order to find the differences between them, I had to compare the part numbers from the other manufactures listed in the SM. That lead me to compare ECG152 (121-966) to the ECG184 (121-808). I found datasheets on them from AllTransistors and they are definitely different, but I don't know what those difference would translate to or if it's even an issue. Since this voltage is in just about every circuit of the TV, it must be important.

Can someone with the necessary knowledge take a look?

Thanks!
