Still having problems with this...original message below. I have my -13 and +13 on the vertical IC. If I disconnect the vertical yoke, I get a horizontal line and power LED flashes continuously, so it seems the problem is definitely in the vertical section. I checked the yoke it has about 8 ohms across the windings. Another Philips yoke I have here gives me 9 ohms, so I don't think the yoke is the problem. I grounded pins 6,7 of EEPROM and still no video. I checked all resistors, capacitors and diodes in vertical section. A schematic of the vertical section would be great, if someone can email it to me. An last advice before I give this one to the Dawgs? Thank you.

I repaired the vertical section by replacing the two resistors, R420, R445, D409, D445 and IC500 and repaired my traces that lifted...I double checked all the traces and they are fine. Then, I had blue screen with retrace. Found voltages off on CRT board. Found R50 on CRT open, no help. Resistance across R53 was half what is should be. The other two resistors for the red and green measured correctly, pulled the resistors and measured fine out of circuit so I replaced the IC TDA6106. Now I have raster at all, no OSD, increase G2 and all I get is raster with retrace lines. I checked my -13 and +13 source, they are fine. I replaced the vertical IC again and no change. Any ideas? Thank you.
