I have a 42 in philips tv that wont turn on green light comes on

I have 42 in philips plasma model 42pf5320179 when i go to use the remote it wont turn on , i then flick the mains power switch a few times and it comes on ,,,, this has degenerated to the point that i now have to do this for over half an hour .and i dont know how many hundreds of flicks turning the mains power on and off. when i flick the mains on i hear two clicks and then a few seconds later another two softer clicks ,, i have come to realise that when the two softer clicks sound that it wont turn on , but if the tv makes the initial two clicks and then no others it comes to life within seconds its only about 18 mths old i dont get it i thought philips was a good barnd in plasmas.

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.

    Hi, i sent off for a repair kit in which there were 4 bag transistors that bolt to the heat sink in the middle of the power board. After undoing a bolt the transistor wobbled so i looked on the other side and a 'dry joint' was visible at the base of the transistor - i re-soldered it and all is now wonderful. I think the heat sink structure is maybe too rigid for the amount of heat movement - hope this is helpful

There may be a simpler solution but that depends. i had the same tv except when i tried to turn it on i got 7 red light blinks and it wouldnt turn on. wouldnt hurt you to try this first. find the 2 10v capasitors next to each other on the power board bottom leftish. if they are both bulging or bloated solder on a pair of new ones. they are like a buck a piece so maybe you'll save some money. hope you spend $2 instead of $100 :)

This is a common problem on these plasma TV's. The problem resides in the high voltage boards known as the X and Y Sustain boards.. You can purchase them here for a very reasonable price:
http://www.discount-merchant.com/Y-SUSTAIN-FOR-42-PLASMA-TV-PN-6871QYH036A-p/sku9510.htm

The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here:
http://www.discount-merchant.com/X-SUSTAIN-6871QZH041B-6870QZE017D-6871QZH052D-p/sku9509.htm

To test which board is failing, you need to check voltage input to the YSUS board first... Input should be 120V from Power supply, output should be above 250V.. Do this test with XSUS disconnected. IF 250+V exists, then XSUS is damaged. If not, then the YSUS is the faulty part.
