Hey everyone!
MT I hope you're still around, and have some insight for me. I have a JVC X590BU here that has a Red | Orange | Red solid LED on the front indicators, they dont blink or go off, they just stay solid red, no clicks or anything in the projector, and it wont do anything else if pressing the power button either.
Now, here's the sticky part - the projector has had water damage, and it appears to have come in near the vent by the HDMI ports. I pulled the main board and sure enough there is corrosion around the HDMI ports, and ethernet port, on the side with the 3 large IC's (which would be facing up towards the ceiling if ceiling mounted, down if floor/desk mounted).
I didn't do any checks with power applied yet, but I did do some checks with the test points on the main board, all but 4 of them have some sort of reading, the 4 that do not are right under the corroded HDMI ports. Now I don't know 100% if this is why the projector refuses to do anything, but its a start I hope.
What I guess I am requesting is guidance on where to check for voltages that would indicate what part and component is having the issue in the projector. I don't *think* its a ballast or power supply, they appear to be untouched from the water, but im not sure if something fed back to them from the mainboard due to the corrosion or not.
Any assistance would be helpful MT, like I said, I'm not so much looking to be able to repair it (dead main IC for example) as much as I am looking to find out IF it is an IC or something minor.
Thanks for your time!
Jeremy
