The monitor loses the video signal intermittently, but when the “power” button is pressed, the monitor starts working again. Some monitors present this symptom due to a defect in the H385 voltage regulator IC batch Monitors that have a regulator IC with this specification: h36* or h38* and have an intermittent “no video” defect must replace the IC with another according to the specification: g960t45r; 1203-002853, position of the regulator IC on the chassis according to its version: ha15a/b-> ic 601; mh15a/j/n->ic 103; mh17a/j/n-> ic 103; mh17f->ic 300;mj15a/b/c->ic 602 gs15m->ic 602.

White balance image flicker; -raster. Procedure: 1st) test the device to check the symptom. 2nd) if the device presents one of the symptoms mentioned, open the device and clean the pins of the CN101 connector on the monitor's video card. cleaning the pins must be done with a contact cleaner (for example: wd, contact matic. ) 3rd) close and test the device again: - if the symptom has disappeared, record this defect in the service orders with code c99 ( other mechanical adjustments) and not with code b01 (welding). - if the symptom has not disappeared, check the other electronic components. Note: also applies to sync master 753v / an17v* chassis models; sync master 753s / an17l* ; sync master 591v / le15*.
