This TV sometimes turns on but does not respond to panel commands. When it turns on, if I turn it off, it won't turn on again. | The problem was solved by changing the SMD regulator on the main board u701 g1084-33 3v3 regulator of the micro, it was changed, instead of 3v3 it was with 4v8, it was just a matter of changing it and the television started working normally again. | ||

Customer reported that the sound was lower than normal, I asked to bring the speakers for an evaluation... | Toasted coils, suspension removed from the speaker cone, speaker wires bare, probably connecting more speakers in parallel and lowering the impedance, total damage, almost burning the amplifier. | Whenever I carry out maintenance on these powerful devices (mainly Sony and Aiwa) and with owners who abuse the volume, ask to bring the boxes, these I will have the coils replaced from 4Ω to 8Ω, and add a 10r x 10w resistor to the tweeters to avoid burning out altogether. | Trendset |

It turns on normally, when an image with any video signal appears, it turns off and sometimes restarts and the stand by LED does not flash, which could indicate a possible failure. | In my case it was due to a failure in the connectors on the rulers, I made the connection with a thin wire between each ruler and its respective point and it solved the problem. | Alberi F S | |
