Philips 42'' Plasma TV 42PF7320A/37 red led error codes

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

    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...

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.

Philips 42PF7320A blinks 3 times every time i hit the power button


The SSB is small self contained board that u connect your Antenna, and HDMI to. An error three is a communication error between the SSB and to Logic board ( located underneath the SSB on the back fo the plasma panel that is just below the power supply. U can check parts.com and see if u want to purchase a SSB for this TV. Is the 3blinking lights coming from the front of the TV. Also check the power supply and see how many times the green led blinks on the upper left of the power supply and let me know.
