I recently bought a Philips 42'' Plasma TV model # 42PF7320A/37 that I replaced the Y-Main board and both upper and lower buffers. TheTV now works great except sometimes when I turn it on I get 1 or 2 clicks and then 6 long red LED flashes and then 3 short red LED flashes. Can someone tell me what the error code means?
I've done circuit board level repairs at a former job, so if the problem is at this level I should be able to take it on.
Thanks
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.
3 flashes indicates that there is a problem in the power supply circuit. Being that you have experience with this, you might be able to fix it.
Help me please

You were corect about the power supply. I already have it fixed. Thanks
Do you know what 7 short red flashes mean?
So far we have replaced the power supply board and the small signal board on our 42PF7320A/37, and neither has solved the problem...
