Title
Samsung LNT4669FX-XAA TV Power Supply Board Replacement
Introduction
I was given a free Samsung Television model LNT4669FX-XAA that wouldn't power on that I found on offerup.com.
I've found other free TV's on craigslist.org, letgo.com and other online sites. These are good sources of electronics to practice on if you are a student, hobbyist or whatever compels you to save some electronics from going into the junk yard. Enough of the electronics restore, repair, re-use and recycling advocacy.
The gentleman that gave me the TV noted that his father had tried to repair the TV before and it worked for a day. He wasn't sure what his father had worked on.
When I brought the TV home and plugged in, I found it did nothing.
I took off the back cover and found a blown fuse and an assortment of new capacitors that I wasn't sure were even in specification.
I decided for the price of a new board, I'd buy a new board (found for ~$20) off eBay and try repairing the old board later with a Shopjimmy.com board repair kit.
I replaced the power supply board and the TV is performing up to specification from what I can tell now.
