SAMSUNG (ps51d6900dm) TURNING ON ISSUE
The problem is the tv turns on and gets to the logo but then turns off! tries 3 times and for safety reasons stops trying to turn the tv on i believe.
I did a few checks and by no means am i very knowledgeable when it comes to fixing tv's but i checked all my voltages and they seem to be fine and disconnected other boards yet still came to the conclusion its the power supply.
I then heard about heating the board with a hairdryer to see if it turns on! which it did turn on. So i isolated it to a part of the board and found when i pushed on the IC the tv stayed on when not heated. I then believed it was a cold solder joint. It worked after re soldering this area for a week! then the same problem happened again! Is this part likely to be causing this problem and if so where can i get this part as i have had no luck looking myself!
Photo attached of IC i believe is faulty!
