Turns on, performs functions, but without audio and inoperative mechanism motors! and sometimes it worked normally and then crashed. | Smd resistors, in parallel, r427,428,487 and 488, both 2r2 1/8w altered and hot frying, on the regulators supply line, | Put one of 0.47r 1w. resolved the defect. | bitencourtmaster |

Doesn't start. totally dead. | Low power supply. around 20 volts. tsh short. but as it came from another workshop and was messing around, I don't know if the "mechanic" couldn't solve it and tried to complicate things more, or gave an exorbitant quote to justify his inability. because the TV was all messed up. at power supply, horizontally and vertically. | Power supply capacitor 2540 (100x25v) (located next to the power supply regulator), and 7402 (bu1508dx). I resoldered the vertical core, it was loose (some "mechanic" came by). | Eletrônica R-Tec |
