Re: power supply bn44-00259a dead

I replaced the diode IN4740AS - zm801 found in short and magically the TV is on and everything is back to work properly. I could not find the diode and I used a zener diode compatible. The problem has been resolved. Thank you.

Re: Samsung LE26B450C4W Dead

Thanks for the reply and I apologize for my English I translate with the help of google translated. I unplugged the power board BN44-00259th, the power is turned on and I find about 326 cp 815 volt fuse on that FM802s. (I find the same voltage 326 volt tester positioned DCV). Fuse is OK. The connector CNM802 I do not detect any tension. The mass was taken from pin 10 which is the mass of the CP 815 but I do not detect anything. I noticed that the diode zm801 measured by the tester was short on the card so I disassembled and measured again with the test...

Hello I have read several posts on the subject but I have not found a case similar to mine. The TV is dead no picture no sound no red light in.standby. Checked voltage CP 815 = 326 v.dc. on the power circuit BN44-00259A. The connector CNM802 provide no evidence output voltage. The capacitors seem undamaged no anomalies. I replaced two electrolytic capacitors (CP809 and CM808) leveling power of the integrated FAN 7530 and who had a ICE3BR0665J ESR too high unsuccessfully checked all the diodes and transistors involved but do not come out
Who can help me?
thanks
