| Sony | KV32XBR37 AA-1 | NO RASTER | KV32XBR37 serial 80139945. Unit has no raster. Has sound, CRT filaments, and high voltage. Led in front is flashing | Tech may have a IK failure. When bringing up the G2 the raster will appear with full vertical sweep and a purple screen. Not much green. Tech needs to look at the IK buffer collectors on Q771, Q772, & Q773. Normally with beam current there shall be about 1 volt on each collector. With the CRT Socket removed all collectors must drop to ""0"" volts. Q771 did not. It was 1.2 volts regardless if the tube was connected or not. Tech needs to short Q771(E&B) and see if the collector will drop. It did not. TV will need a replacement Q771. Replacement cured the symptom. "" | Muller |
