Hi and welcome to the site,

Initially, all the video output mode passes through a video selector IC (BU4551BF) and a 3IN 6OUT Video Amp (LA7135AM). Failure of either or both would result to no video feed to the monitor/TV. The audio passes through a different circuitry and therefore would not be affected.

Offhand, this would then be a hardware fault and require the Pioneer DV-F727 to be opened up to confirm diagnosis and effect repairs. Options then are:
  • consider a DIY (do-it-yourself) repair if and only if comfortable working with electronic components & circuitry, use of a DVM/VOM, a soldering iron/station, preferably a scope and safe practices with electrically powered devices. Access to a Service Manual or at the very least, a schematic diagram would be a necessity;
  • should you be uncomfortable with a DIY, perhaps your best bet would then be to consult with and/or seek the services of an authorized Service Center or a qualified professional.

Are you considering a DIY? If yes, I can provide the schematics/Service Manual (if necessary), guides to test points and repair procedures.

Good luck and thank you for asking.
