Samsung LCD TV 8 times blink red diode /wont turn on/
« on: July 13, 2017, 04:13:31 pm »
Samsung le32s86bd, Power Supply: BN44-00192B / https://elektrotanya.com/samsung_model-le32s81-main-bn44-00192a-bn44-00192b_inverter_sm.pdf/download.html  /  . Tv won't turn on. If i press power button, red diode on stn by blink 8 time. Black screen, no sound. On every button from remote red diode blink.
I open tv and i have 2 caps 1000/35v bad. I replace them, and after that check all caps on power supply with esr meter, they are perfect
Voltages from PS:
I have all correct voltages on inverter /24v/ stable.
5v -correct
13v -12.2v
12v-11.8v
BLU-5V
ADIM-0V
DET-5.3V
GND-0V
PWM-0V

On connector CNM801, pin1 = Power_On/Off I have stable 3.3v.CM856 (1000MF/25V) was very bad (216mf ) i check with esr meter. After this procedure i remove IC501 (eeprom) and from my laptop with programmer i delete eeprom and put it empty the same chip. In this mainboard i see also IC3208 (on my pic) which is also the same like IC501, but delete only IC501.
