JVC 3ccd KY19 repairs

[ellahfrank]

Please can anyone tell me how to solve this problem. My studio camera JVC 3-ccd ky19 is not displaying anything on the view finder. When switched on.. It shows blank. They are two cameras. One is still functional. When the circuitry was opened, four cards were found. The card carrying a transformer with a reflective heat sink seperating it from the others is bad. I fixed the card in functional camera and the view finder went blank...no image. What can I do to solve this. Please email me on [email protected] If I could get a fairly used functional card...I would not mind buying it. Thanks all
