Re: SAMSUNG led un32eh4003f Plays melody No picture & led blink
Power Supply board is definitely bad. Checked another one and the voltage across each LED array varies from 20V with back-light set to 0 to 105V with back-light set to maximum of 20.
Thanks

Yes, that is my board. There are two LED strips each with 9 LEDs.Leave a comment:

Voltage readings were taken between Gnd and each pin. I also took the voltage reading between pins 1 and 2 - 22.4V and pins 4 and 5 - 22.4 v. This is a brand new TV that has been sitting in storage long enough for the warranty to run out!
Disconnecting the LED cable seems to shut down the voltage to that connector. I do read 176V on pin 1 but it slowly discharges a cap and by the time I check the other pins they are at 0V.Leave a comment:

Adjusting the backlight also has no effect.Leave a comment:

Re: SAMSUNG led un32eh4003f Plays melody No picture & led blink
Hi,
I have the same model and I've checked all of the LED's and they are on but don't seem very bright. I can see the picture but it is very dark and I can't make it any brighter with the brightness/contrast/etc adjustments. What should the voltage be on pins 1/2 and 4/5? I get 22.4 V on each set with pin1 to chassis - 152V, Pin 2 - 129V, pin 4 - 129V and pin 5 - 107V. Any help would be appreciated.
ThanksLeave a comment:
