This time I repaired a Skyworth 32 LCD TV 32L01HM, the fault is AV, TV image is normal without sound, teardown check the sound circuit inadvertently touched the sound block, so hot, quickly disconnect the power supply, thinking that the sound block is hung, the hand temporarily There is no replacement for the same type of sound block, so I will try to check the peripheral parts of the sound block first. When I find a 35V1000UF capacitor, I find a short circuit, remove the measurement or short circuit, and think that the fault has found a quick replacement for the same model. After the change, I am looking forward to the EVD, dumbfounded, or the sound of the waves is still, continue to struggle, finally hard work pays off, another capacitor next to him is also a short circuit, and immediately remove the measurement or short circuit After the replacement, the machine was tested again. This miracle finally appeared. The sound was loud and vivid. After a long time test, the temperature of the sound block was normal, and the fault was eliminated. This experience was dedicated to everyone. (The two capacitors look good, no drum bag leaks. phenomenon)
