Please, please, please - if you don't know what you are doing stay away from attempting this as the risk of serious injury or worse is very real.
If you get any sort of electrical shock while working on this you need to get your heart checked for damage.
Tukkae - how do you know your x500 needs a ballast? I thought there were pretty reliable in the later JVCs.
karalisd - 384VDC from the PSU is correct, it "should" be about that AC on the output of the ballast. The ballast itself detects if it is putting out the correct voltage, that is how the projector gets the error.
Hi Luke, I know where the ballast is located but for some reason on the x500 it might be even worse to get to. The PJ has been unplugged for long enough before I started working on it, so I should not be at risk of electrical shock.
The reason why I think I need a new ballast is that I originally thought I had a lamp issue (as described here https://www.avsforum.com/forum/24-dig...ot-my-jvc.html
) but after reading up, I believe the behaviour of my PJ is more in line with a ballast issue. Especially since I only have 225 hours on my lamp.
So the problem I'm facing right now is that the processor board on the top right is not coming off.
The only way around it is to be able to remove the entire tray that sits across the PJ and separates the electronics from the lens assy. However that also doesn't work because there are screws that are impossible to get to at the bottom which would indicate that the processor board needs to come out first.
I'm obviously reluctant to use too much force to try and remove the processor board since it's not something that should require any when the top screws have been removed. However, like I said, I believe that the actual CPU that sits on the underside of the board is attached to the underlying metal frame and built-in heatsink by way of adhesive cooling paste. Any tips to remove this would be very welcome.
Did you face the same issue when working on the RS45's you had Luke??
