Philips tv red blinking light

SOURCE: red light blinking

My one take too long to turn on, relay/green light on and off for hours before it can start, I use a hair dryer to heat it up everytime, aim at the center from top, then it turn on very faster, no need to service

I have the same problem, except with a Philips 50 inch model 50PF9631D/37, except mine sometimes does 6 long flashes and 3 short. Here is what I found, after MUCH online and other research:

It is probably the Power Supply board. One other indicator that it is the power supply board is that if you unplug it for a minute or so, and then plug it back in, it might start up and stay running until you shut it off again (that is what mine would do). Mine eventually would not come back on after repeated unplugging. I have learned that the reason for this is leaking capacitors on the Power Supply Board. If they are really bad (like mine eventually were), the TV will not come on at all. The reason it will stay running once it is going is that there is a separate set of circuitry for the TV once it is going.

I UNPLUGGED my tv and waited 1 hour (for capacitors to hopefully discharge), and then opened up the back of the TV (all you need is a "Torx" (also known as star-head screwdriver, with 2 different sized bits (buy multiple bits if necessary, they are cheap and I don't remember the sizes).

PLEASE NOTE: Even unplugged, TV's have capacitors which store large amounts of electricity which can discharge quickly and kill you. Be very careful. One website suggested wearing special, high-voltage rubber gloves.

The Power supply board is the big computer-looking board in the center. I stared at mine for 15 minutes and was able to notice 2 capacitors with slightly bulged tops. I have learned that this is a common problem with these boards. All you need to do to remove the board (at least with mine) is to carefully (there is a little clippy thingy on the bigger ones) unplug the wires connected to it, and unscrew the screws holding it in with a phillips-head screwdriver.

I was able to find a replacement board at various places on the internet, but the best was BestBuyParts. I found they had 1 Original Board for mine for $300, an updated replacement for $300, and a refurbished replacement for $205. I ordered the refurbished one and will let you know my success when I get it. Interestingly, the original board was made by Samsung!

Interesting side note: I tried to simply replace the $1.00 capacitors on the board to save money, but they are REALLY hard to find. I finally found that the original capacitors, made by Samwha, are no longer sold as 105 degree celcius capacitors, but are now listed as 85 degree capacitors, and their 105 degree replacement is now back-ordered. I have also ordered approximate substitutions, to see if I can save the old board. Bottom line: It looks like Philips bought the board from Samsung, who got some bad capacitors from Samwha, and we all pay the price.

Finally, check to see if there is a recall. 12,000 Philips TV's with Ambilight have bad capacitors which are sparking and have been recalled. I doubt it is related, but I bet I know who manufactured those bad capacitors.

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.
