Today, I received a 42-inch "SAMSUNG" plasma TV, the model is: HP one 4254, the power-on test machine only heard the power board relay 嘀嗒 ... 嘀嗒 ... åå¤ repeated suction sound. Because of this repeated suction and continuity, the fault surface is relatively wide, and every plate of the whole machine has the possibility of causing it, so there is no accurate initial judgment. To this end, the cover is re-powered by a conservative inspection method: 5VsB, 5.3V, 12V and other voltages repeatedly beat with the sound of the relay, and Vs and Va are not output. From these data, it can be inferred that the power board has been in trouble. . In order to be cautious, it was decided to take the power board offline and start the further detection independently. The result is still the same. In desperation, I forced Liangshan: I had to perform component level screening on the power board one by one. First check the working status of each power tube. In this operation, I got a surprise discovery: one is located in QX801, model In order, the field tube of 11N50CF is broken down. 0K, hope is the final ending! Therefore, the dismantled parts are replaced with a pipe of the same type, and the other components are inspected. After the abnormality is not found, the power board is reset and the test machine is powered on. Charges: US$268. Receive the team, send a picture. Thank you!
