Hi Richard, If in doubt always change the vertical IC. They are cheap and don't always short but go open like you found.

I never saw one of these open before and it's just like one of the output stages quit, I guess the diode supplies the power to one side. > > THANKS TO ALL> > > > Richard La Placa > Continental TV > 312a Park Row > Chestertown, Md,21620 > Fax&Phone-410-778-1113 > continentaltv@xxxxxxxxxxx > > > > > > >From: <tvservice@xxxxxxxxxxxxx> > >Reply-To: techassist@xxxxxxxxxxxxx > >To: <techassist@xxxxxxxxxxxxx> > >Subject: [TechAssist] Re: RCA m#F27689,ch#CTC197AS-top half of scan missing--bottom half has retrace lines over picture,&brighter horiz line across center > >Date: Thu, 22 May 2003 13:34:39 -0500 > >MIME-Version: 1.0 > >Received: from turing.freelists.org ([206.53.239.180]) by mc10-f5.bay6.hotmail.com with Microsoft SMTPSVC(5.0.2195.5600); Thu, 22 May 2003 11:34:23 -0700 > >Received: from turing.(none) (localhost [127.0.0.1])by turing.freelists.org (Avenir Technologies Mail Multiplex) with ESMTPid C6687390CF6; Thu, 22 May 2003 13:32:25 -0500 (EST) > >Received: with ECARTIS (v1.0.0; list techassist); Thu, 22 May 2003 13:32:17 -0500 (EST) > >Received: from smtp802.mail.sc5.yahoo.com (smtp802.mail.sc5.yahoo.com [66.163.168.181])by turing.freelists.org (Avenir Technologies Mail Multiplex) with SMTP id 201A5390C32for <techassist@xxxxxxxxxxxxx>; Thu, 22 May 2003 13:32:17 -0500 (EST) > >Received: from adsl-67-66-169-89.dsl.rcsntx.swbell.net (HELO robertshop) (tvservice@xxxxxxxxxxxxx@67.66.169.89 with login) by smtp-sbc-v1.mail.vip.sc5.yahoo.com with SMTP; 22 May 2003 18:34:08 -0000 > >X-Message-Info: vAu4ZEtdRigLaEiTQQBlDPU44G8LMD9u > >Delivered-To: techassist@xxxxxxxxxxxxx > >Message-ID: <003c01c32090$ff5efae0$0501a8c0@xxxxxxxxxxxxx> > >References: <BAY7-DAV35IssCQqUk3000022d9@xxxxxxxxxxx> > >X-Priority: 3 > >X-MSMail-Priority: Normal > >X-Mailer: Microsoft Outlook Express 6.00.2800.1106 > >X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 > >X-archive-position: 5046 > >X-ecartis-version: Ecartis v1.0.0 > >Sender: techassist-bounce@xxxxxxxxxxxxx > >Errors-To: techassist-bounce@xxxxxxxxxxxxx > >X-original-sender: tvservice@xxxxxxxxxxxxx > >Precedence: normal > >X-list: techassist > >Return-Path: techassist-bounce@xxxxxxxxxxxxx > >X-OriginalArrivalTime: 22 May 2003 18:34:23.0228 (UTC) FILETIME=[C400EBC0:01C32090] > > > > > >Richard, > > tried to send to your continental address print of vertical for ctc197 > >but e-mail was sent back > >will try again > >Robert > >tvservice@xxxxxxxxxxxxx > >H & H Electronics Inc > >Dallas, TX > > > >----- Original Message ----- > >From: "Richard La Placa" <continentaltv@xxxxxxxxxxx> > >To: <techassist@xxxxxxxxxxxxx> > >Sent: Thursday, May 22, 2003 3:40 PM > >Subject: [TechAssist] RCA m#F27689,ch#CTC197AS-top half of scan > >missing--bottom half has retrace lines over picture,&brighter horiz line > >across center > > > > > > > Hi > > > Can anybody tell me what the voltages are at the vert out IC#U14501 > >should be?
