Okay, this totally sucks. The analog board on my SE converted to an SE/30 has possibly bitten the dust. It must be the vertical sweep IC (U2) that failed or something else. It suddenly began showing a black screen with a bright single horizontal line and now is just a blank screen. Looking up what to do, it was suggested to try resoldering the P1 connector or that the chip is bad and replace it. If I don't fix this, I would be going totally blind when I do SE/30 logic board recapping.

I was looking on eBay and found this. My question: Can anyone verify if whether that analog board is fully compatible with the power supply and CRT I have? The power supply is a Sony CR-44 Apple P/N: 699-5047 and the CRT is:

Clinton Taiwan Corp.

CE792M9H118GHZYB

CEULL76 1/4 A1TE

Apple P/N?: 630-5144

If not, I will try replacing the vertical sweep IC on the original analog board and see what happens. Luckily, I can get the part individually for $11.63 from Mouser.com.

Thank you for your help.
