Re: Samsung led tv #UA32C4000PA with no backlight


so exactly which part should i start checking from voltages or the circuit. coz i've checked all the leds in the string and all are ok.check the above post.i've attached a pic of the powerboard mentioning all the voltages im getting from the circuit.see if u can find anything. and why theres no voltage power from 2 of the resistors(i've marked them with thr zero voltages.checked the resistance of the pins,seems to be ok with 0.6ohm resitance)...

Re: Samsung led tv #UA32C4000PA with no backlight


i tried to check the voltage on that ic. the voltage on pin 1 starts at (+-)190-200v and drops down to 0...the rest of the pins stays at 0.9v. I've attached an image of the actual board with real voltage output mentioned on some of the pins. plz have a look....

hello badcapians!
I have a samsung led tv model#UA32C4000PA with a power board model#BN44-00349A which I'm trying to repair.
the tv starts normally. passed flashlite test for picture. sound ok. only issue is theres no backlight from the tv. overall visual inspection found nothing fried or burnt. all capacitors and other components look good.
I tried to first check the power output from LED driver pins thats marked +led1. it shows a measurement of +85-89v while the -led pins shows 0. I tried to open the entire panel for checking the led's on the strip. all LED's seem to be...
