Larry, The only problem I have seen on this board cause shut down is a leaky pin diode, DL032 I believe.. This will be difficult with an intermittent problem: >From Tech Repair CD: RCA\D52W19 ITC222\Troubleshooting\\\ITC222\Set should power up with the CRTs disconnected\Disconnect the H & V yokes*Disconnect BW001 & BW002*Disconnect BA010 (audio)*Disconnect BP611 to convergence PS\If the set powers up reconnect one at a time trying to turn on the set* and troubleshoot that circuit that caused the shutdown\If the set will not power up when these are disconnected the trouble is on the small signal board\\\\\ Jeff -- Intrepid Video TV/VCR Repair 263 S Front St, Steelton PA 17113 717-939-7708; (F) 717-564-4952 www.intrepid-video.com www.tech-repair.net ----- Original Message ----- From: "larry" <[EMAIL PROTECTED]> To: "ELECTRONICS PROFESSIONALS LIST" <[EMAIL PROTECTED]> Sent: Friday, July 23, 2004 7:42 PM Subject: Re: [Techs] Fix..?? RCA PTV D52W19 screening problem...???
I think i have a similar problem with the same type set, itc222. this is intermittent dead, about once every 2 days. the led blinks but wont start. the error code says bad 5 v. switched. when it does finally not start, i can flex the boards , and finally it works again for 2 days. i have tried my best to isolate the area, but can not. so i installed a new signal board, with RCA advice, and it still does this. i dont have much hair left to pull out. i have to assume , now that it is on the sweep board. but i still cant come close to the area. it seems to fix it any where i touch it, when it is ready to start. any advice appreciated.
