Originally no tuning.Also seemed to have some white residue inside the Gemstar module I cleaned. (looked like water lime residue). Customer says she can not make the Closed Captioned work . Where does the CC function originate? Gemstar? Would like some info before it comes back. I assume she knows how, as she has another identical set she uses it on. Phil Bader -------- Original Message -------- Subject: RCA F27615 / CTC203AX1 no tuning/no+33v, fix Date: Sat, 13 Dec 2003 10:09:55 -0500 From: Philip Bader <tjanphyl@xxxxxxxxxxxxxxx> Organization: Jan Phyl TV Inc. ,Philip Bader To: "techassist@xxxxxxxxxxxxx" <techassist@xxxxxxxxxxxxx> This version has the seperate small upright tuner. measured all tuner pins, none had +33 volts (or even close). Back at the SMPS (located at front left chassis) located the +33V source. Starts at smps transformer pin 16, to diode CR14106, branches off to several pionts. One of which was resistor R14119, 15K ohm/2W. Open. This went on to zener diode CR14107 (33 volt)., then C14111 (100mf/63V),C14158 (1mf/100v). Changing R14119,Zener CR14107 restored the 33V to tuner and operation was restored. Change the two mwntioned electrolytics as precaution. Phil -- Philip Bader Jan Phyl TV Inc.
