Assuming it is Philips 47PFL7432D lcd tv as mentioned in question headings.
There are two possibilities for said symptoms,
Either power supply board or back light inverter board is defective that can cause said problem.
Let me know if you have prior electronics stuff repair experience to help you with further info or call local tv repairman to get tv fix.
Thanks.

    Sorry for delayed answer, I was away from computer
    Check power supply output voltage to determine is it working fine or not.

Red Light/Blue Light I/O Error


My nx2 is working again after having the "red light/blue light/I/O Error" problem. I just:

1. turned off my computer
2.unplugged the HD,
3. took out the HD from the enclosure and plugged it back into the enclosure,
4.started up my computer without the HD being plugged in
5. after my computer had been on for a minute, I plugged the HD in and my computer recognized it and had the proper mixture of red and blue light coming from the HD, indicating it's working properly.

Good luck!
