Samsung LE26R86BD
« on: September 23, 2014,15:17:47 »
A cordial greeting to all,
I have this TV Samsung LE26R86BD with the defect: it tries to turn on but the LED is still flashing,  power BN44-00191A is good and after some testing I noticed that the signal "main_power_control" pin 2 cn1101 coming from the main  BN41-00813e cyclically from 0v to  3v and as a result tensions on power BN44-00191A up and down.
Someone just happened? and this signal comes directly from the main cpu or some regulator ..
Thank you for any suggestion.
a greeting
Attilio ..

Hello Michael,
thanks for the reply,
the psu is ok and already changed ic 1803 as Sparky says it could be a problem of cpu BN41-00813e. Before I try to change it with a reflow and will let you know.
greetings
Attilio
P.S. I translate with google I hope you understand .... :57:
