The cinescope it is not ignited, the led is ignited alone of ignition, the relè is ignited, the noise comes from the part of the feeding section. The frontal panel has a its transformer regarding the mainboard. The main is XOCECO (Xiamen Overseas Chinese Electronic Co Ltd) 16HO - 82 - 51052 - 011 - ADV. They are shrewed that the member who fries is C3025 transistor mounted on a dissipator. C3025 is connected: base: to the emettitor of a A966 and a diode valve with a emettitor ferrite ring: to one coil wrapped in a magnetic nucleus and one 47 resistance of 3W of ohm. collector: he goes to a transformer with ten piedini BDK-0301. tensions measured on the C3025: B-C =
219V E-C = 215V B-E = 0,28V Thanks- posted
