Stopped working. When power is turned on, the relay clicks, the LED power light flashes slowly on and off. The screen is black, no sound. When the power it turned off, the screen lights up white in the center as the picture collapses. This happened once before but then the problem went away with no obvious cause. Also removed power and restored it with no result. Suggestions appreciated.

Re: Power on but no picture or sound
Your problem is from the power regulator IC . Its an str type and has to be an original from tosiba or its parts distributors. Now you may have caused more problems as alot of peeps do trying the set over and over again thinking Oh the set will rest its self.. Nope sorry sir if a set goes bad and you try it once , and it dosent come back on . Its time to seek a repair person to repair and troubleshoot the set for you UNless your a technician? If your not Dont try to repair a tv as these have non serviceable parts for the consumer to replace! And can bite ya in the butt, if your not carefull. We techs cannot teach ya overnight how to fix something. Only assit and to point ya in the right direction. Good Luck

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.
Check its main board. A serial clock-serial data transfer problem occurs. Might be the fault to the main digital board, and be replaced. But, it is best to contact any technician to make it confirm. If you're sound in electronics, check this link. It has details about service help to Philips flat panels. Pull up older posts there, either by its left side bar, or
see it in Timslide option.http://electronicshelponline.blogspot.com/ If you're nothing in electronics, do not go forward. Keep it in mind, that the Brand is Philips; even an experienced technician too have to spend some time before it to locate the exact fault location.
Try the old flashlight test, turn off the lights in the room. Turn on the set and flash a bright flashlight on the screen. Do you see the image or is the screen totally black?? If you see the image, then most likely you have a backlight problem. Verify that you have 24V on the power supply for the inverter
Sounds like the battery might be low which would cause the red flashing light and dark screen. Let it charge for a little bit then try turning it on again. If it still does it with the power supply plugged in, make sure there isn't a lens cover on it, and switch modes or try getting into the menu to see if you can get anything to come up. If that still doesn't work then it sounds like there might be a problem with the camera.
Same problem with mine. Relays click, sound, no picture and a flashing power LED. I finally found a schematic online. I went through the high voltage circuits and found the power transistor 2SC5570 was shorted out. There is also a pico fuse in that area but my was not open. I replaced the transistor and prayed the flyback transformer was not shorted. It wasn't, I'm watching my old 36" right now. Not a bad fix (17.00) bucks. Wonder what a service tech would have charged ;)
