JVC DLA-RS57U LCoS Video Projector Repair | No Light | Ballast Replacement

This DLA-RS57U was sent in after the owner purchased a new lamp that did not work. After determining the projector was the issue, it was shipped in for repair. Being that this projector was made in 2013, the hope was to keep the repair "cost effective" so a different ballast was used. The original ballast costs about $375. The ballast I used sells for around $40. While it runs 20 watts less, it worked out just fine and looks great. I may do a video on repairing the ballast at some point but I think the issue is in the control section rather than the MOSFets since the Fets all checked out. I will add a link here if I complete this. You may notice some continuity issues. I either lost or didn&record parts originally so I re-opened the unit to show the ballast. I have run into this issue a few times before but never was able to complete a cohesive video. Hopefully this helps folks who run into this problem. It applies to a lot of JVCs.
