Immediately after turning the set on It shows the white ''Phillips'' screen, then goes black. Shortly after, the TV appears to turn itself off and back on to the ''Phillips'' screen, then black again and just stays black. There is also no sound. After this it will not respond to any buttons. Repeatedly unplugged but it just immediately cycles through this again when I plug it back in.

hi nel2874
so, you have a television that turns off immediately after you turn it on.
It sound like your power supply on the unit is out. Because I don't know the value of your unit I cannot comment on replacing the unit. But I would recommend that you use our website to find a Flat Panel TV Repairman near you. You may want to call to get an estimate on replacing the power supply before considering replacing the unit.

I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.

Your plasma TV has a power supply 6709900019A. These power supplies failed due to defective capacitors. See the picture below and check the capacitors mark with the red lines. There are 10 capacitors that should be replaced even if they do not show signs of bulging/swelling on top.
The value of the capacitors is 3300uF/10V but you can use 25 volts as long as they fit in the space provided by design.
SOURCE: What could cause a Philips
maybe it was hanging out with the wrong crowd... just kidding.. The only way to find out is to open up the tv. Unless the smoke was coming from near the power cord. When you open up the tv, there will probably be some sort of burn mark on the circuit board where a capacitor may have blown. If this is the case (and provided that the circuit board wasn't damaged too badly, you can get a sodering gun, remove the blown capacitor(s) and see if you can find replacements at your local electronics store and then soder it back in. If not, you might need a whole new circuit board.
