I have an RCA model # P52720BA that looks like the HV splitter went out on. When I remove the front panel and power on the unit I can see the splitter arcing against the metal frame. When I remove the splitter from the frame the unit will power on with sound (static) but the bulbs do not come on at all. There is also a high-pitched whine. I'm assuming this is still due to the HV splitter being shorted out, but wanted to make sure I'm not missing something before I dive in. Any thoughts? Thanks in advance.

Is there any other part I need to be testing in union with this part? Is there a high likelihood that replacing the splitter will make the TV work again (barring anything else being wrong beforehand)?

Horizontal Output transistor may also fail, but is unusual.

Otherwise: How TV worked before this failure, SHOULD be how the repaired TV works.

Thanks for the input. I'm ordering the part now from suburban supply. Let everyone know how it works when I get it installed.
