    (ed blinks 3 times) > problem power supply
    change capacitors 1000uF and others at once it is visible that they "blown up"

    Power supply is not visible ''blow up'', capacitors look better.
    Maybe power inverter, transformers. I check.
    Thanks very much!

    I check power supply, 3v3, 5v, 12v, 13v its ok, and power inverter its ok, maybe mainboard with cpu its damage. :cry:

    How did you check inwerter on CLA320 ??? There are transformers from 400XA series please check them carefully, there should be fault. Regards

    Maybe apparently simply illumination (one from lamps is broken)is not present.
    Check
    -Voltage on the inverter comes 24в. On contact ERROR-OUT 0v, On contact EX-DIM 1.8 V, On contact DIM 3,5V On contact ENA 0V
    - 1) Disconnect from MainBoard all sockets going from SMPS;
    2) Close on SMPS contacts:
    a) 24V-> B/L On/Off;
    b) Pwr On/Off-> Stdby through the resistor 2kohm

    On B/L On/Off submit pressure Stdby (5V), NOT instead of 24V.
    On Pwr On/Off it is possible to submit simply pressure Stdby without the resistor.
    Signal ENABLE (ENA), resolves inverter work, only after installation of modes of the skaler-transmitter and the skaler-receiver. It is similar to signal POWER Vs in PDP. If it is hardware it is connected - active 1.
    To begin with check up LVDS, it is attentive - CLK.
    The inverter joins command B/L ON that means BACKLIGHT ON (to include illumination)
    ENABLE (it is accessible, openly, is included) - this means that illumination is included, when lamps is on , there level 1 when are extinguished - 0

    In Samsung LE32S81B was problem with (if led blinks 3x)

    unpluged the inverter from montage and led blinking the same (3 times), I check inverter measurement at cold and its ok. No diference at inverter beetwen transformers, I check 24v to input and stab 12v, its ok.

    Dodano po 14 [minuty]:

    I check, lcd its in st-by protection, inverter its not comand from mainboard, but i check more!
    Keep searching ...
    Thanks Lisek and Pol Uk!
