At the request of PhilipsPhanatic, here is the copy of the thread I started on the 63" that had red blinking code issues that I resolved...
I am basically putting this thread together for anyone that may have a similar problem with their Philips Cineos 63" Plasma TV #63PF9631D/37. There are similar threads on this subject, but most deal with the 42" version. Although this is similar, there are enough difference to hopefully warrant it's own thread.
With that said, I will give a little background on the problems I had with my set.
I bought the TV back in early 2007 from Sam's Club and mounted it on the wall in our basement media room. The TV was fine up until about a year and a half later when it started showing the classic symptoms of shutting off, the green LED turning red and flashing 7 times. Unplugging and plugging the unit back in (typically repeated about 6 or 7 times) before it would finally stay on.
This frequency of the set shutting off kept getting progressively worse to the point it was happening about once a week. The number of times it took to unplug and plug the set in to get it to work was more and more as well. Sometimes it would take 15 tries before it would stay on.
During the latest round of problems, I noticed that the set was blinking 6 times now instead of 7, for some odd reason. I did notice that with all components off I would unplug the TV, wait and plug the set back in it, the set would stay on with the green LED solidly lit. As soon as I turned on the digital set top box or the Bluray player, the set would immediately shut off and the LED would turn red and blink 6 times.
I read these forums and based on the 42" plasma sets, decided to see if I had the same issue with my 63" unit. I pulled the set off the wall, laid it on the floor and proceeded to remove the literally hundreds of hex screws on the back. Once opened up, it looked like the following picture. This picture is shown with the top of the TV closest to me, basically viewed upside down. This picture is also shown with two of the boards removed. There are some edge connectors that need to be carefully removed, but they easily lift off.
This next picture is a close up of the two boards removed from the set. The smaller board on the left I am calling the power supply board. The larger board on the right I am calling the power driver board.
Notice the location of the 3300uF, 10V capacitors. These are the capacitors people with 42" sets had noticed were expanded on top and had blown. In my case they looked fine. The larger 270uF, 450V capacitors, on the other hand, looked as though the tops had noticeably expanded. Since I had the TV apart I thought I might as well replace those as well. So, I ordered (2) 3300uF, 10V and (4) 270uF, 450V capacitors from Digikey.
This next picture shows the new capacitors. They are as follows:
270uF, 450V Digikey# 493-2864-ND
3300uF, 10V Digikey# 493-1754-ND
I removed all the old capacitors and replaced them with the new ones. Be sure to observe the polarity. There is a white stripe on the capacitors that is the negative side of the capacitor. This goes back in the printed circuit board aligning with the thick solid white marking printed on the circuit board.
Installed the boards, reconnected the connectors, put the back on and stood it up. I plugged the set in, hooked up the digital set top box and VOILA! A picture!
I hope this may help someone out that has the larger 63" Philips Cineos plasma, with similar problems to mine, get it up and running. There was no way I was going to pitch a 2 year old set!
