Hi, I find the fuse blown in t-con board. But I can't determine the value in amps on this.

Hello there!
Have this Philips with no image at all. When I plug it to the outlet, it turns on without pressing the power button, and after a moment, it turns off, then starts again. I checked the 12v and 3.3v voltages on the main board connector that goes to the T-con, but it only has the former (12v). Any clues, guys?... -

This TV was showing a fine image and pulsing with a partial double image (offset vertically) every few seconds. I taped 8 clock pins on one ribbon cable from the Tcon to the panel. It stopped the double image, but some pulsing in intensity was still visible. I then taped another 8 clock pins on the same ribbon cable and the image is now ‘fixed’. Although I understand this results in some loss of resolution, presumably because the clock signal degrades as it passes horizontally across the screen.
I am wondering - do these symptoms and ‘fix’ mean that it’s a Tcon fault or... -
