| Exactly when I move g2 I can see the raster but with the cushion effect.
It fills all the screen. rgds mloo55 |

| Resolder C32 connector on the crt board. 25kv sounds low. When you turn up the screen do you have vertical deflection? | |

| In short the filaments are on, HV 25kv approxx, audio ok, power supply voltages normal. I moved the screen pot an the raster is visible. I took volatges at IC301 and some values are abnormal like these:
16 5.30 (3.9) 17 5.3 (3.  18 5.35 (3.9) 19 4.29 (5.5)
20 0.26 (2.3) 21 4.8 (6.0) 22 0.26 (1.9) 23 4.33 (6.2) 24 0.26 (1.9) 26 7.0 (4.7) 27 0.20 (7.7) 38 1.8 (2.7) 44 1.90 (2.4) 45 1.7 (2.2) Readings in parenthesis are from schematic. Is the IK protection the reason these readings change if so what action could I do/ rgds mloo55 |
