Question about Samsung HP-T4254 42 in. Plasma Television
What you have wrong with your tv is in the power supply board, it is a very common problem which you can fix yourself for around $30 this is a MAJOR Samsung problem and thousands of people are having this problem. What you need to do is deenergize your tv and lay it face down on a table so you can work on it. Use a philips screwdriver to remove all the screws on the back cover of the tv make sure to remember where they go for when you put it back together. Remove the back cover and follow the two wired from where your tv power cord comes in and in the middle of your tv they will plug into a board, this is your power supply board. Look for blown capacitors, also check the fuses the tops will be bulging upward and caps have writing on them like 10v 1000uf or 2200 uf and 3300uf are the most common. What you will need to do is replace these with a 16v cap but be sure the uf number is the same, and you need 105 degree rated caps. There is also a negative side to the capacitor which is marked with a stripe and a shorter leg on the bottom, these have to go in the same way or you will blow the board, remove the board with screwdriver and disconnect all wires, now you will need your tools solder, soldering iron, and preferably a solder ****** to remove the old bad caps here is a youtube link that shows u step by step just go there and type samsung power supply repair, and whether you have a vizio, philips or another model that this is posted on they all have samsung power supplies in them so if you are having power problems this is your fix, you should be able to get all your parts at radio shack or on the web.
