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.

hello, amigo if the all the caps are godd then you have to replace the power supply board. don't try to fix it this is not an easy task. you are looking at almost $200.00 with tax an shipping. just go to google and type your tv model # and ask for the power supply board or just look for the part# on the board itself. good luck

90% of the time this is capacitor related in the power supply, Remove the back and check for capacitors that are domed shaped on top, Replace these and all should be ok.

Since Philips service manuals do not list a chart for the LED blinking diagnostics, the first thing to look for is faulty electrolytic capacitors on the power supply board, one of the most common causes of failure in plasma tvs. The capacitors are cylindrical objects with an x or k mark at the top. See if you can find any of them on the power supply that are inflated(bulged) at the top and/or cracked. Please let me know what are your observations sot that we can proceed accordingly.

Philips 42" Model # is 42PF7320A TV Yr. 2005


Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light flashing codes, circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

I hope I shed some light on the subject for you.

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


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.

Error 7 is a power related problem. This is what u need to do.
Remove back cover.
Plug in power when tv goes into error protection, check power supply and see how many times the led flashes. Right below the flashing green led there is a list 1-13 of error codes and what they mean. Your problem will probably be an error 7or 8 VSET or VSCAN . Which ever error code it gives you VA VSET or VSCAN or whatever it indicates look at the cable connectors to the power supply unplug that connector and the TV will stay on. And there will be your problem.

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.
