Ed, Not sure how you can place one of these in backwards. The thing with the legs formed the wrong way, merely means you got a wrong OEM part. Emerson, I think, is the one who has their regulators proprietary to them, even though they have the same STK number.

When you chnged the Regulator, did you put it inthe right way, some non-OEM regulators have the legs formed the wrong way. I have been a Toshiba ASC for years, and this circuit gave no other problems after changing the components mentioned. I would suggest you backtrack on the replacements you have done. -Ed- Ed Gaidies Tel-Tek Electronics Ontario-Canada teltek3@xxxxxxxxxxxx ----- Original Message ----- From: "Alvin Rose" <ajroseca@xxxxxxxxxxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Thursday, August 21, 2003 3:08 PM Subject: [TechAssist] Re: Toshiba Model cx2950c chassis 8820 Dead > Hi Jeff > the capacitors replaced were high ESR ..C841 blew out again after I > replaced > Q801 and Q802..replaced it with a 160 volt rating but it gets hot after > a short > time..Set comes on but is in on the sides..Is the rectifier D840 fast > switching > or regular diode Do you have the voltage rating of the zener D841 > thanks > Alvin > Intrepid Video Support wrote: > > >Alvin, > >This sounds like the same set I am working on. > >Were those capacitors you replaced high ESR? > >Also...check the two diodes side bng > >Intrepid Video TV/VCR > >263 S Front St > >Steelton PA 17113 > >fax...717-564-4952 > >www.intrepid-video.com www.tech-repair.net > > > >----- Original Message ----- > >From: "Alvin Rose" <ajroseca@xxxxxxxxxxxxxxx> > >To: <techassist@xxxxxxxxxxxxx> > >Sent: Wednesday, August 20, 2003 7:42 PM > >Subject: [TechAssist] Re: Toshiba Model cx2950c chassis 8820 Dead > > > > > >Hi Ed > >c822 was changed with a 100 Mfd 50 volt electrolytic and r820 checks ok > >at 68 ohms ...Is there anything else that can cause this problem..I have no > >schematic for this one...Will replace c841 with a higher voltage unit > >A.R > > > > > >>-Ed- > >>Tel-Tek Electronics > >>Ontario-Canada > >>teltek3@xxxxxxxxxxxx > >>----- Originaere anything l Message ----- > >>From: "Alvin Rose" <ajroseca@xxxxxxxxxxxxxxx> > >>To: <techassist@xxxxxxxxxxxxx> > >>Sent: Wednesday, August 20, 2003 6:13 PM > >>Subject: [TechAssist] Toshiba Model cx2950c chassis 8820 Dead > >> > >> > >> > >> > >> > >> > >>>Hi Guys > >>> > >>>We have a toshiba CX2958c chassis 8820 which was dead > >>>replaced c863 and c866 also c841...
