    Same problem here with a Phillips 42 PF9630A/37.
    Was given to me as a good tv but it never worked.

    Will make clicking noise when plugged in, green led in front will be on for 2-3 seconds, then the red led will flash 7 times, then skip a second or 2 and flash again 7 times.
    Anyone know what might be the problem and where to order part if fixable? Thanks.

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.

    Update: I was able to find replacement capacitors at I bought a soldering kit at Radio Shack ($8), and a desoldering iron at Radio Shack ($12) and was able to replace the defective capacitors. I have never soldered before, so I practiced on paper clips for an hour before I tried it on the TV circuit board. This site was a little helpful, too Although it is more focused on replacing bad capacitors on computer boards, the concepts are the same.

    P.S. I was wrong about the Samwha capacitors being 85 degree instead of 105 degrees. That was a different version of their 3300 uf 10 volt capacitors. I don't know why these ones failed, but they sure seem to be failing for everyone.
