Re: JVC av-27920

Eric Posted Jan 13, 2006, in response to:Robert

Robert you mentioned that you replaced diodes. Did you check D422 the 75V Zener? Also how is the 25V Vcc to the Vertical Out IC? D541 and R541 have been known to open. You did state that you're sure that the problem is in the Vertical Out Circuit but I've seen C914 (470uF 200V) in the Raw DC Supply cause lines in the pix and reduced height. I have the Sams if you need it. Eric

    Hello Eric Yes I have changed the usual,including the Zener.The problem as you suspected is the 25 volts.Not there.I realized it before I posted the message. I would appreciate the manual as I am going to have to trace were the voltage problem is.I changed the cap as you suggested even though my ESR tester said okay.No go.Thanks Very much Rob
