Was watching tv. It turned off and the led indicator started blinking red in five time intervals. Won't turn on long enough to reset it. Already tried to unplug it and all the troubleshooting from the Manuel.
These blinks [flashes] are fault indication (Error Codes).From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it.This will make repair easy.These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times.Count it carefully.If you wish to get some details, check the site linked here.It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given.Surf the site with patience.

My 42" Philips LCD did the same red blinking sequence last night. All was seemingly fine after unplugging it for a bit. An online search, though, has me worried that this may be the start of (potentially fatal) power supply issues. Anyone have a clue what that sequence means?
I've got one week left on my 1yr waranty, so I'm a bit concerned! :(
Thanks!

Hi there,
4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.
Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.

Most problems with TV not turning ON is a power supply related problem. The relay click are a normal process that powers up the circuit boards. Right now the TV is most likely in " Protection Mode ". The TV detected a bad circuit board and it will prevent the TV from fully turning ON. This keeps the other circuit board from being damaged. The power light blinking is a code.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet. This will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, blinking light codes, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.

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?
There's a guy or a company on eBay that offers trade-in for faulty power supplys, you should check them out:

Search for 37'' Philips in the title or contact them to ask about it. Used to be $99 flat including return shipping.
A firmware update is necessary. Contact the nearest authorized service center for Sony.
Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen A2 slightly.
