With sound, LEDs on without image, giving the impression of a defect on the display | I checked on Vcon the voltages vghp 30v, vgh, vgl were absent, to my surprise, I replaced the main board and it solved the problem. | It seemed to me that if the vcon supply voltage is either below or above 12v the ci tcon goes into protection. | Eletrônica Valdecir |
