My Tv Samsung Ln-t4032h Doesn't Turning On.

a well known issue. you need the power supply repaired. this is a symptom of some filter capacitors going bad. these parts are generic and replacement parts are available at Radio Shack and such.

The capacitors look like cylinders with a flat top on the power board (where the AC power cord hooks to). The bad ones will have the top puffed up slightly. The values are printed on the side and are probably 1000 microfarad at 10VDC, replace them with same value at a higher voltage rating as long as it will fit it the same area on the board. you can replace them yourself or take the parts and the board to a shop and they can install them for about $25

My problem was that one night my TV just shut off. The tv would not turn back on again. If I hit the power button the lamp light would blink a couple of times and then with a click it would power off again. I replaced the lamp which seems like the magic fix-all for this tv but that didn't work. I then called for an in-home diagnostic ($89.00). The guy told me it was a problem with my power board at would be about $600.00 to fix. They would have to pick up the tv and diagnose the problem with the power board, also claiming that the boards were no longer made and they would have to find and repair the failing component. I found the board at samsungparts.com (no longer made, my a**)and ordered it for $114.00. If you can add or remove a hard drive in your computer you can replace essentially any board in the tv. It is just a matter of undoing the screws, unplugging wires, and replacing the board. 

Today, I am expecting to receive my new power board so I pulled the old one out. It was kind of wedged in the slot and so I, stupidly, I'll get to why in a moment, drilled a couple of holes in the board, ran a wire through the holes, and yanked it out. I drilled through some solder on the board, thereby breaking it. Anyway, I still hadn't removed the connector from the power board to the ballast; on the power board it says "to ballast". So, I removed the connection and low and behold my problem stared me straight in the face. It was a blown fuse behind the connector to the ballast. Likely a $1.50 at radio shack or less. So, one lamp ($150) + diagnostic ($89.00) + new power board ($150), my total came to $389.00, when it could have been about a dollar fifty. But, I'm still happy. I'm going to need a new lamp at some point. So then my total is $289 as a cost to fix. Had I not destroyed my first board then I could have returned my new power board, but oh well. I'm happy that I didn't get suckered into having my tv shipped from my house for 10 days and pay $600.
