PHILIPS 23PF5320/28 No power and it keeps blowing fuse

3.15A fuse is correct one, if it gets blow that means power supply board is defective and will be replaced.<br />I disagree with *<span id="ctl00_ctl00_MainColumn_CenterColumn_ThreadSolutions1_Repeater1_ctl00_lblSolution">Buldging Capacitors* idea because output chips are shorted out in power supply board and blowing fuse that does not happen with bulge capacitors.<br />Power supply board part number is </span>310432836212 and price would be around $140 or so<br /><span id="ctl00_ctl00_MainColumn_CenterColumn_ThreadSolutions1_Repeater1_ctl00_lblSolution">Thanks.<br /><br /></span>

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Link to a photo of the PCB. Make a note of the location of all cable connections then unplug them all. Un-install PCB, Check a Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

May try to replace your power supply. Average cost runs $200 via Internet. Also may inspect test & replace deformed an or any bulging caps.
