Samsung LN32A330J1N LCD T.V has no picture when powered on


This can be one of two problems. The backlight inverter board is bad # BN44-00235B <or A $60-80
Or one of your backlights is bad/broken. Not a easy repair. Single lamp is about $16-25 whole kit $150. But finding a great tech who can or will take the screen/light box apart to do it will be the biggest task. Takes about 3 hrs to do. And if you do NOT know what you are doing,you will damage the screen.
Then you just throw it away. But if your lucky, it might just be a bad connection. If it comes one after it goes off. But if it just flashes on for a couple seconds then does not come back on, Most likely bad backlight/or inverter. It goes in to protection mode.I have seen in a couple of Sony's it being the T-con board "LCD control"board do the same. $60-125
I wish I could give you better news. It is not easy to tell the problem on that without testing out each lamp "15-20 of them w/a lamp tester" or checking out each transformer on the inverter board. Verry time consuming. This is why I push the Extended Warenty. LCD's still have bugs to weed out. Plasma's are even worse.

My samsung LN37B550k1fxza, Has Sound But no picture! day old!


While it is playing, sound that is, try holding a flash light right up next to the sceen, preferably in a dark room, and see if you have any picture. You really have to focus on it and watch closely. If you can see any picture, you probably have a bad inverter. The inverter lights the back lights in the panel to illuminate the picture. The flash light basically does the same thing from the front. The inverter is the board on the far right with several of the same kind of wires disapearing down the side. Thanks. Let me know what you find.
