Hi All, From all of what i have read so far this is a wonderful site hope someone can please help.
I have a Samsung LE46C530F1WXXU which like many others has a problem, it will power on get the chime a flash of the screen then it sits black and can not see anything, then 15mins later it goes into standby.
After seeing many others on the net with problems, i changed the caps and went up to 25volts even though they looked ok. I contacted Samsung and they advised was a power supply problem but the capacitors are not affected on this model, i do not have a service manual to work from so its difficult to check voltages. The power supply board is BN44-00341B was only made in 10-3-11. One thing i did try was to disconnect the T-CON ribbon cable and power up, it made no difference which led me to believe it could be faulty, i seem to be going round in circles, and possibly missing something simple, have even looked at replacing all the boards for £59 but none in stock. That is the easy way out and world just love to find the answer and fix it.
Any help would be really appreciated.
Many Thanks

hi when you get these problems with samsung no picture fault usually down to buffer boards and y sus board, these are located on the left hand side of the tv, check the main fuse on the y sus also the soldered fuses and, it would be best to check the fuses on the z board this board is on the right hand side good luck.
