JVC TV model AV-56WR30 flyback
I have this set in for repair that has the flyback arcing internally.
Does anyone have a service manual in which they could please look up the part number for me? My distributor cannot find it. Also I read somewhere else on another NG of a "flyback regulator" , I don't know if that transformer was also arcing but they mentioned a blown STRF 6655 flyback regulator. I am not familiar with the term Flyback regulator. Are there other components around the failing flyback that I should be concerned about as well? Thanks, Lenny. |

" put finger to keyboard and composed: I have this set in for repair that has the flyback arcing internally. Does anyone have a service manual in which they could please look up the part number for me? My distributor cannot find it. Can you see any writing on the FBT itself? Try HR Diemen for an equivalent: http://www.hrdiemen.es/products/inde...anguage=eng-GB Also I read somewhere else on another NG of a "flyback regulator" , I don't know if that transformer was also arcing but they mentioned a blown STRF 6655 flyback regulator. I am not familiar with the term Flyback regulator. It's a term that describes a particular SMPS topology like buck, boost, buck-boost, push-pull, half-bridge, full-bridge, half-forward.
