Turns off by itself, sometimes it doesn't turn on, sometimes it gets a greenish screen, it makes noise from the speaker and turns off. | It may be caused by several possible problems, carry out the following procedure to resolve and avoid a possible return. | Check the power supply and inverter board for swollen capacitors and replace them. Remove the power supply components: c108, zd111 and zd112. Also at the power supply, replace the 11k resistor r128 with a 15k or 18k one. On the main board, replace the SMD electrolytic capacitors that are close to the processor and RAM memory with values of 100μFx16v and 10μFx16v. Clean the main board well on both sides with thinner or isopropyl. resolder all fets, transformers and heatsinks on the power supply | GABSENS |

Does not turn on, no standby. | Zd101 changed, it was not shorted, but not behaving as a diode. | Changing the zd101, which when measuring on the diode scale leads on both sides, and measuring low resistance, replace with 1n4746 18v zener diode, the pwm vdd appears again and the monitor is ok. | MARCO BORSATO MEDTEC INFORMATICA |

Burned power supply, considerations to fix the power supply 715g8962-p04-000-003s | Damaged primer. u8601 (pf6002as), the pf6002ams or tpv002ams doesn't work, I didn't test the tpv002as, I couldn't find it to buy, so first I bought the tpv002ams, I killed myself and finally I confirmed that the "ams" is incompatible... then I found the pf6002as and the TV worked. the transistor q8601 (p0765atf, I used 7n65 mosfet channel n) follows the resistor values of the positions, if it carbonizes you don't know the value: r8603(470Ω), r8602(100Ω), r8601(22Ω), r8604(10kΩ), diode d8606(g6), u9801(ld7592), u9101(ld5537), u8605 secondary power supply (tpv101ad, this is another one that doesn't work, another tpv101 with other terminations), transistor q9401 (btc4672m3). | This TV, after being repaired, the TCON was also broken and the voltage going to the LEDs was 26.1 volts... | MIGUELTV |
