'Any TV/VCR repair people out there?? 'Got a parts question.... I'm repairing an RCA VT385 VCR. The DC-DC converter is out (design error, it overheats and dies, new one has heat sink). I have a Sams Photofact schematic on it. The replacement converter states to always replace Q808 with the converter. Q808 is described as a "IC Protection" device on the schematic. No RCA part number is given in the Sams. The number "ICP-5N" is shown on the schematic. I looked in a TV parts catalog I have (EPS parts supply) and they have a similar device (looks like a small signal transistor w/two leads, not 3) in the catalog listed as "IPC-5N" (not ICP-5N). I think this is the same part but I'm looking for verification on the net. What is this part? Is it just a diode that fries if overloaded? The part is in series with a raw, 21 VDC source, has an inductor in series with its output, connecting to the DC input of the converter. 'Any answers out there?
