SOURCE: 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.

SOURCE: tv red blink no start42 plasma philips

Thank you for the help. I actually changed the whole main power supply board and it still did not fix the problem. When I put the new one in, I had the tv on for about 3 hours and then I shut it off. No sooner did I get it back up on the wall and the problem started all over again.When I pulled the original board, the caps all looked fine so I am not even sure the board is bad. Problem is there is no one around me to test it. I am not going back to the same shop that already told me that it was a bad main power supply board. Any other suggestions?

SOURCE: my 42pf7421d/37 flashes a red light when i turn

Hi, philips (sony and others) uses the flashing red lights to give an error code, but all that means is that a circuit is probably shorted and doesn't always indicate specific components,.
42pf7421 is an LCD that basically has two large circuit boards in it. If you have technical ability you can examine the power supply to see if any capacitors are swollen on their top sections. this is a common failure in many LCDs and Plasmas, but would require soldering to replace them. If no caps look swollen troubleshooting this set would involve voltage checks , a service manual and board replacement.
Could be either the main board, power supply or possibly a bad screen (panel) If you have the set open you can sometimes see the LCD bulbs light for a split second indicating that a problem with either the panel itself or the ballast power section. If it lights for a second sometimes I can see that one bulb is not lighting. One bad bulb will cause the set to go into shutdown mode , indicating a bad screen (panel) .
I hope this info helps you decide on the options before you
1. call a tech expect to pay an estimate fee, parts and labor btwn $200-$1000
2.check the power supply, reseat the panel cable, look for a momentary light of the screen. order a suspected part and replace it yourself.
3. buy a new TV (sry bad option)
hope this helps
Eric

No picture on Philips Model # 50PF7321D/37


The LED normally blinks--indicates the digital/main board is powered up.

Look for other fuses----Boards for these are rather expensive, maybe too expensive.

Google the model number with the word boards or parts after it to research it.

relay clicking is a power board failure --- part of the board still works to supply power to the flashing lights--- the lights are related to an error code while in protection mode
