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).

The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop. mecry.gif
And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.

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 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

relay clicking is a power board failure --- part of the board still works to supply power to the flashing lights--- the lights are related to an error code while in protection mode
