I had the same problem with the same model. I took off the back of the television and checked the two small fuses. They were fine, unfortunately. So I bought the refurbished power board from Best Buy using the part number that I found on the web. Swapped out the board and the TV works fine. Now I need to know what to do with the old board. I feel badly throwing it away since it is probably some simple part.

Re: Did you ever get your Philips fixed?
That specific flashiing is the software in the computer, the television has inside
you need to go to the philips website and download an upgrade software repair it is free-- put it on a thumb drive without any other things on it---- the television ,must be on to install --- turn it on with the remote and then insert the thumb drive-- the television will run a scan--- then turn off television and wait a few minutes-- turn it back on with the switch on the side of the unit-----
the power problem is something else--- the power board sounds like is going bad--- a new one is around 300-400 and a rebult unit is around 100 --- you can find them on partstore.com
this television is poorly built -- when you get the new board it is easy to install -- before ordering a new board -- check the fuses on the board-- there are two fuses -- one is 1amp and the other is 5amp -- both are slwo burn fuses

i am having the same problem. My Phillips 37" 37PF9431D/37I LCD High Definition TV won;t turn on. When I press the power button i hear a click and the green light comes on for a couple of seconds and then the red light appears. I can;t figure it out. Did you find a solution?
The Ymain Board is out if you have the back of the tv exposed disconnect the ymain board and then plug in the tv set and turn it on. the light should remain green and no longer flash. If this happens the Y main and upper and lower buffer boards should be replaced
finally got some help from customer service ----
the code flashing one then two red lights is for an upgrade of the software ---- you can go to their website and download a current fix to that problem onto a thumb drive----
\the power problem is caused by a bad power board--- you can replace them for any where from 130-330.00
dont need a service tech - take off cover and easy to replace---can find part on parts store.com for philips televisions --- used is about 130 and new about 330 -- used is a refurbished unit and works just as good as the new one
power board is bad if it doesnt power up -- the red flashing lights mean that you need to upgrade the software-- you can get a new software upgrade on the website for philips --- use a thumb drive to install it into the television
While I can't tell you what this particular code means I know from experience that power boards fail frequently commonly on those TVs. Do you hear a clicking of the power supply first on and then off after a few seconds?
I had the same thing - one long red flash followed by four short red flashes. Plugging and unplugging the power cord had no affect until I also unplugged all the cabled connections to the VCR and DVD player as well. Also, per the manufacturer's instructions, I unplugged the power cord from the surge protector and plugged it into the main wall outlet (which I tried first, but did not finally have success until I cycled the power cord unplugging process with all the cabled connections to the auxilliary devices unplugged as well).
