Most likely the power supply capacitors are going bad.
Opening the TV and replacing any swollen caps may solve your issue.

There is circuit problem inside. For safety reasons power might get shut down! Unless the fault is rectified, this problem will continue. Do not attempt switching ON again & again. Get authorised service center assistance.

Call 1-866-771-4018that is the tech support for Philips.

sounds lick you may have a dry joint in the powers or line o/p stage.

as a rare fault it could be the crt with an intermittant internal s/c. but you would notice the colour was tinted either red, green, or blue in the dark areas of the pic.

Its your bulb on its way out.

the replacement bulb is a Sony XL-2400 But yours should definately be under warranty

How many times Red Lamp flashes, its important as it shows problem and its location in tv. Below is detail of lamp blinks and you may know the problem area in tv by counting lamp flashes.


Need further help, let me know.

Rollo, broken solder connections either in low voltage or sweep section of the board, probably in the horizontal out put area but could be anywhere. If you want to attempt the fix the board has to come out and you`ll need a bright light as well as a good magnifying glass to find the broken joints and then re-solder them, Be certain your tv`s AC cord is removed from the wall outlet before doing any soldering, good luck, BMW Rider

try removing one neck board at a time and see if it stays on and longer,don;t let the board touch any metal or a short wil follow and you got problems.try the red first,
