I will try and describe this the best I can, but I have a IN116 projector that has no power at all when plugged in (yes my power cable is fine) on the board when checking all the way to the bridge rectifier I have 164 VDC same for the primary to the first transformer. on the secondary side I have 5 VAC
Now it has a 2nd transformer near the outlet to the ballast or main control board I get the same 164VDC to the primary and nothing for the output on the secondary side.
On the board mounted on the heatsink are 3 things..
D10XB60 bridge rectifier
K20A60U
FSU10A60
The wire that plugs into the ballast is saying 390V/0.64A on the board so I guess that's what the output voltage should be?
The power supply is the only thing wrong with this and if someone could help me pinpoint where in the circuit is the issue that would be great.
If you need any close ups of some areas of the board I can do that.
