This set came in with blown fuses.
I've changed all four IPM's on Y-sus and Z-sus to be on the safe side.
Powered up straight away but I'm worried about the heat off z sus ipm's.
With digital temp probes sitting on the fins these are increasing from ambient to 40 deg c in 5 minutes. I bottle out after then for fear of the things blowing up again. IPM votage is 18.2 V.
Now the Y-sus is running much cooler 32 deg c in 5 minutes. Ipm voltage is 16.2V.
Has anyone got a working set on the bench to check temperatures for me. If not a 50" a 42 " should tell a similar story.
Also- connected an old analogue scope with x10probe to check wave forms. Can't seem to get anything like manual says I should.
Anyone have advice about scoping plasmas would be appreciated.
