The first thing you need to do is establish whether there is an actual fault with the MR or whether it's a setup/connection issue. You haven't indicated anything you have already tried in order to rectify the problem so I'll have to start at the beginning with the basics:
Isolate the MR
1. Make sure the MR power is off using the "POWER" button on the front of the unit.
2. Disconnect ALL cables from the back of the MR. If you have several connections be sure to make a note of where they all reconnect
3. Unplug the MR from the power outlet and leave disconnected for at least 5 minutes.
The software/firmware in a MR can "crash" in the same way that your PC does. Unplugging it for a few minutes should re-boot the system - basically the same as starting up your PC.
4. Plug the MR into the power outlet again but do not connect any cables.
5. Switch the MR on using the "POWER" button on the front of the unit.
If the MR is still stuck in standby, you have a fault with the MR.
If the MR will power on:
6. Switch the power off again and re-connect the cables for one device at a time then test the MR. Make sure the cable are connected to the correct sockets.
I suggest you connect the TV first then test the MR will power on. Next connect the cable box and test the MR again. If everything is OK, continue to connect any other devices one at a time and test the MR after each connection.
If the MR fails to power on after connecting a specific device, this will give a good indication of where the fault is and what to do next.
If you can re-connect all of the devices and the MR functions correctly, then it was just a simple case of the MR having "crashed" and you can resume normal operation. Should the fault re-occur, simply unplug the box, leave for a few minutes and switch back on. You can avoid disconnecting everything unless the box fails to power up after the "hard reset" - i.e. unplugging it.
This is a very simple test to determine what/where the fault is. Please try all of the above and then post back with the results if you need further assistance.

Hello, I to had this problem, and my original media receiver finally died. I did however go to my local electronics store ( I'm not talking about the big box stores) And bought a $7.00 dvi to hdmi adapter. I simply unplugged the "system cables from the back of the media receiver and placed the adapter at the end of the DVI side of the cables, and plugged the now hdmi side into my hdmi splitter box and I am off and running! The only downfall is it does not carry sound only video. But this in not a problem for me as I have a surround sound system. This was a very inexpensive fix for me/ I hope this helps.

This is a classic "Hic-upping" switchmode power supply problem. The protection circuitry inside the SMPSU, has sensed a severe potential problem, and is attempting the shutting of the set, down to avoid a fire, explosion, or both.
This set had developed a problem, that is so severe that the set must be shut down, (This set should be removed from the Power),
What is happening is the internal "Fault" that is causing the Protection Circuitry , to detect the problem and attempt to shut down the set, keeps restarting the set, because as soon as it shuts down, the "Faulty" component(s) cool down?, and the "Fault" ostensibly "Clears" so the PSU starts up again, only for the component(s) to heat up, whatever, again and fail, so it shuts down, and if left unattended, this would continue on until the part eventually failed. As related this is called a "Hic-upping Power Supply". Any fault that involves the power supply is usually quite serious, and needs a professional, usually, unless one is familiar with servicing current day, televisions.
And in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center. Now, this point is very important for a good result, Always contact, their "Local" or a, "Head Office" Philips in your case. Ask them, for a referral to an authorised servicing center, where you ask for a "Quote". Now, when you get the information you want, then you can decide as to repair of replacement.
The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done.
service manual link above,
as an aside here, sometimes things in storage can quickly degrade especially big low value capacitors, these increase in internal resistance, and all sorts of problems ensue, this is why, say, military things are cycled at least weekly when in "Moth balls" to prevent exactly this.
