TV does not turn on, red "standby" LED, when checking the power supply I noticed the lack of 24 volt voltage. | By replacing the EC4 "33UF/25V" capacitor on the power supply board next to the PC4 photocoupler, the problem was solved and the TV started working normally again. | Rivaldo Lira | |

This sound sometimes comes out as normal audio but then the audio stops coming out on all channels, 5v does not reach the irs 2092 | After measuring all the power supplys, they are normal, the solution was to remove the q 1401 and it resolved this transist, I couldn't find it to buy or the equivalent so I chose to remove it, tsound's no point in testing | naelson silva gravata pe | |

With sound and without image | When carrying out the necessary checks, I noticed the lack of 18v voltage on the zsus board. | When inspecting the ysus board, we noticed that the 18v voltage comes from this board, next to the two photo aclopad you will find the capacitor c204 (150μF/35v), being shorted it causes this defect when changing the TV it returned to normal. | Rivaldo Lira |
