Lower the current of the LEDs, place a resistor, or mount a 12k one between pin 35 and the negative of the IC 9500 chassis Lower the current of the LEDs, place a resistor, or mount a 12k one between pin 35 and the negative of the IC 9500 chassis Tsound's even a soldering point, it's the smallest point: Rodrigo Cofferi Rodrigo cofferi

AZ3G 		Flashes 6x LED stby protection Remove the cable located at pin 3 of the cn6401 "power supply connector" from the connector, bl_error, ground the cable on the side that goes to the main PCI. If the atv turns on, tsound is an open LED on the panel that activates the overcurrent protection. RUBENS S.OLIVEIRA

Right after switching on, the LEDs turn on, protection is already activated and error 6 keeps flashing LED drive circuit, after the help of another board I was able to remove the LED drive c.i. and place it in the place of my board. this c.i is the one with several smd terminals on the right side of the board, ok...I forgot to check the position and now that I'm posting the tip I remembered Replace c. i drive the LEDs, be careful with the soldering station, components fly out if the air is too strong.

Works on 220 but 127 doesn't turn on and the red LED keeps flashing Remove 680k r9347 from the power supply board, clean the glue and replace the resistor, do the same with the other two resistors in series with it. Marcelo

Turns on, lights up green, gives a quick flash of LEDs and the LED stays red with an error of 6 blinks. In my case I had a LED kit with cable and everything and I tested it, I was able to confirm that it wasn't LEDs, I also had a 40w655 main board and I tested it instead and it worked perfectly, even the power supply to the LEDs crashed, I thought it was strange, but the pwm must correct it as it "sees" the consumption of the LED kit and corrects it. Changing the main board, I'm not trying to find out what it was...that's for another opportunity. MIGUELTV

TV restarts 3 times and turns off with the LED flashing 6 times. The bd9397efv c.i was arming the protection...I changed the leds and nothing, I cleaned the leds and nothing, I changed the c.i itself and nothing, I changed the 39x50 capacitor and nothing too...so what I did was the following... pin 31 of the ic 9001 is the timer protection, and on this pin tsound is a capacitor, I removed it and put a 10k resistor to disable its protection... and the TV worked without turning it off again, I left the TV in test for 15 and without presenting the defect. Put a 10k resistor on pin 31 of the ic9001 and remove the capacitor on this pin 31...tv ok eletronica cachoeira

Switching off after 10.5 minutes, sometimes in less time 12v power supply on ic32 (dda001ag) being cut off Just replace the ic53 (photo-coupler) obs. even if you do well on the test Deo Eletrônica 8198904-0186

Turns on the backlight, the LED is green, but without an image on the display, all voltages are normal, including the dcom. Clean the display's flat cable on both sides, clean the board with thinner and then reflow the display's dcom board. Amarildo Callai
SONY KDL-40W605B
When turning on the Stanby LED TV, it goes from white to green for a few seconds. At that moment the baklight comes on and the image appears for a few seconds as well. The TV turns off and the standby LED flashes 6x constantly, going into protection. TV controls are blocked. Just turn it off by pulling the plug from the socket. Baklight protection circuit on the LD board/LD HM2 board with a problem. the ld_err line on the cn1000 connector was 1.26v when it should have been 0v. Checking continuity with a multimeter, I discovered that this line reaches an SMD NPN transistor located above the IC2000. Tsound was a shorted ceramic capacitor next to this transistor, preventing it from saturating and changing the voltage from 1.26v to 0v. Replace the capacitor with a suitable one and the TV started working normally again. We can confuse it with a LED defect, or, worse, condemn the screen. IZEletrônica
