Frank and All, I used the proceedure listed below, to locate the bad cap. It turned out to be C250 (100ufd. @ 16 VDC ). I used a 25VDC replacement, cause it was completly blown. ********************************* I never believed in pulling caps.What I do and it's fast and effective is to display a NTSC signal which will indeed show the problem since after stripping the carrier,the different colors occupy different spectra.Select a electrolytic that covers all voltages of the existing caps and lets say 10 ufd .Stay away from sensitive circuits[uproc etc]and just go down the video chain while watching the signal.If you see a slight change check the cap your'e bridging and bridge again w/proper cap.It will be dramatic and obvious.Don't forget that satt. Reeivers have raw video as well as regular video and those ckts need to be checked. Check raw video first if you can .Let me know..........Regards, Pete
