Samsung UE50NU7090U , no power , no led standby
By inserting power, on the diodes DM856...Dm859, there are 9 volts, when you press the power button the voltage is 12 volts, voltage present for a few seconds, then returns to 9 volts
The power LED remains off, always.
Reprogrammed Ic 503 = 25Q40 and IC 501 = 25Q80, downloaded from the site
The situation remained the same

Are you sure that U1800, INTEL SLJ4F BD82Z68 BGA Chip Chipset, does not overheat? I have the same problem, powering the board with a bench power supply, PP12V_G3H_ACDC, I have a current draw of about 400 milliamps and U1800 heats up about 40 degrees Celsius.
L7710 to gnd I measure 45 ohmLeave a comment:

With a bench power supply I powered PP12V_G3H_ACDC, the 501 LED is on, I measure a consumption of about 400 milliamps, it is known that it heats U1800

Problem, when pressing the power button (S5010) everything is off, led 501 is on.
On the power supply pins there are:
Pin 6 4v6
Pin2 12v
On the power button there are 3v3, which when pressed generates the signal SMC_ONOFF_L, which goes to pin 104 of U4900 = H8S2117 LFBGA
On L7710 there are 3v3, on L7750 0 Volts
PP12V_G3H_ACDC 12v O.K.
=PP12V_G3H_S5_FET
=PP12V_G3H_3V42

APPLE iMac A1311 ,no power
Main board : 820-3126-A
Power : OT8043-290H R03BE9-0008I- apple P/N: 614-0444
EMC 2428
Problema , alla pressione del tasto power(S5010) tutto spento , led 501acceso .
Sui pin dell'alimentatore sono presenti :
Pin 6 4v6
Pin2 12v
Sul pulsante power sono presenti 3v3 , che alla pressione si genera il segnale SMC_ONOFF_L , il quale va al pin 104 di U4900 = H8S2117 LFBGA
ho difficoltà nel capire quale sequenza , quando arriva il segnale SMC_ONOFF_L, deve
eseguire U4900 per attivare l'alimentatore

Re: Samsung QE65Q800TAT
Disconnect the LVDS cable, the backlight is not present. 25Q40 is definitely corrupt.
I need the dump of 25Q40.

Re: Samsung QE65Q800TAT
After more detailed checks, the power LED turns on, stays on for about 5 seconds, then turns off and on again. The relay turns on and off, like the power LED, in an infinite loop,
in all this the backlight remains off....Leave a comment:

Defect: Off, voltages on the power supply ok.
When you press the power button, the TV makes a clicking sound (activates the relay),
the Power LED continues to remain off.
The 13 volt voltage on the power supply is ok.
By disconnecting the cable from the main board to the power supply, the TV backlight turns on.
I suspect the flaw is the main board, any suggestions are valuable.
I couldn't find any wiring diagrams online.

LG 42LS570S-ZB,lampeggia led accensione per poi spegnersi .
Chassis CHASSIS : LD22E
MainBoard EAX64307906
Supply Board EAY62608801 EAX64427001
Difetto : lampeggia led accensione per poi spegnersi .
Le alimentazioni sono presenti in uscita dell'alimentatore .
O.K. 24V
O.k 12v
O.K 3.5V_ST
Il problema , sicuramente è sulla MainBoard EAX64307906 .
Ho misurato le seguenti tensioni pin 19 di IC3000=R5F100GEAFB , POWER_DET 1v9 , tensione presente per
pochi secondi , per poi tornare a 0V.
Lo stesso accade per +1.5V_DDR , generata da IC2403=TPS54319TRE

LG 43LJ594V-ZA, turned off.
Power: LGP43DJ-17F1
Fault: No power on the secondary.
I have checked diodes and transistors and they are ok. Resistors are o.k.
Replaced IC101 = SSC3S927, IC601 = SSC2016, still no secondary side voltage
I need the schematic and some repair tips.

Defect: Lighting o.k., audio o.k. no image, scart output image ok.
The F01 fuse is blown, the cause is due to U101 = tps65161 broken. After replacing the U101, I have the following voltage values on the T-CON:
