Durabrand DVD Player PVS1970 Won't Play
Hi,
I have a Durabrand DVD player in my service shop that won't play. The power light is on and when a DVD is inserted, a "Loading..." message appears on the monitor. Then an "invalid disc" message appears. Note: An audio disc has the same effect. The disc does not spin and the pickup head doesn't emit a beam (momentary) nor does it move in/out (focus attempt). A web search did not produce useful information regarding the problem. Thank You in Advance, John PS, Remove "ine" from my email address |

It probably sold for about $29.00, repair parts and schematics will NOT be available, its Chinese junk at its worst. If a simple cleaning of the laser lens doesn't work, stop. |

Usually one single LSI controls everything end even decodes/process video. Not worth repair like the old Cyberhome crap. any of you here work with industrial drives or just drives in general? We purchased a bunch of baldor VS1MD41 AC drives (1 HP) which has vector mode in it, that's a nice thing and they're economically priced how ever, it took me a week in my spare time between other jobs to get the drive to go into Vector mode. The parameter H40 has a range of 0..2 in the manual, and Selection 2 is for sensorless vector. Using that did not put the drive in Vector mode but in some other mode that acted more like basic V/f control. An accidental discovary of scrolling the UI on the drive on H40 option showed that 0..3 range existed! but according to the manual, that's wrong how ever, I select #3 and there it is, Vector mode and it works great... I down loaded recent DOC's from baldor, no change has been made in the H40 parameter... I don't know if we have a bunch of drives (40 of them) that has a problem in firmware or baldor just isn't aware of the DOC error ? The reason I speculate on this is, the drives my employer purchased do not have the membrane type keyboard like Baldor is currently offering but uses real push buttons how ever, the lay out is exactly the same... So we either have older stock or maybe newer stock ? Either way, there is an eror in the DOC's and this POST is going to help those that failed at it or maybe wake up some one... Have a good day.. Jamie.. |

Jamie.. I have some experience in Yaskawa CNC drives and resolvers but that's about it. I know Baldor makes replacements but what you are referring to are microdrives. You may have discovered some documentation errors or as you said firmware errors but I'm no expert on it albeit I do understand somewhat your deployment. -- Live Fast, Die Young and Leave a Pretty Corpse |
