SOURCE: Philips 42 inch HDTV - "FlatTV" Plasma -- does not turn on.

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. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all 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. Look to see if the Caps are deformed and or split at the top. 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.

SOURCE: why wont my tv turn on? a red light just flashes

Right now, your TV is in " Protection Mode". A damaged part has occurred inside on one of the power supply boards. The red flashing light is a trouble code for a tech to trace the trouble circuit path.

If you have electronic experience with circuit boards, you can find a Service Manual for the TV on the internet for less than $20. This Service manual will have the schematics, red light codes, circuit diagram, and part number list you need to fix the board.

SOURCE: TV won't turn on

my philips plasma tv just shut of on me one night, i tried everthing 2 get it working. A repairman said to fix it approx $450.00. I paid over $2500.00 3 YEARS ago didnt know if it was worth paying out that money and then it breaking down again. For three months i kept the tv untill i decided what 2 do, couldnt bring myself to trash it. So this week i took of the back panel there was so much dust inside carefully removed all the dust, Still it wouldnt work so then i decided to go to where the powercord is to see if anything burned out, it hadnt. I followed where the cord went to and noticed that there was a fuse beside where it when on the board so i removed it when to lowes and bought replacement fuse for $1.75 put it in and bingo it started back up after about 4 months of trying.I hope it works for you. you have nothing to loose you will have to either trash it or let some repair man rip you off . Good luck

Power light but no picture or sound


Hi!
My name is Chris.
I have this Phillips Wide Screen TV that didn't have or come with a remote, so I had to go out and buy a universal remote for it today from a BIG W Store. I'm having some technical difficulties & problems with switching and turning it on, but as I use the universal remote to turn on the TV, I'm having a bit of a slight problem with it turning it on, Ok, Yes, it works and Powers on, but there is nothing showing or giving me the indication that there is no picture or sound showing up on this Wide Screen Phillips TV, But there is a little red & green light at the bottome right hand corner that keeps on flashing red when ever I use the universal remote to switch the power on. Is there a possibility, that i can get some help on here, to help me out with any suggestions, is to why I'm not getting any picture or sound showing up on this TV with this universal remote ? Is there anyway that i can maybe get some help with this to help me out with solving my issue with the Phillips Wide Screen TV ?

It sounds like a main board failure but could be a power supply issue as well. The set will need to be diagnosed
