Just fixed mine, when plugged in red light comes and goes, sometimes it ststays on but when I turn it on the green light comes on then off. Opened up tv, there is a heat shield of some sort,take off, there is a board where plug goes into the wall,it also has three more plugs plus a ground that is screwed to the tv.I looked at the board and there were two capacitors that were bulged and had brown stuff about to come out the top. They were 1500uf 16v 105c, I changed them only I made them 25v instead of 16. And boom life was good. Good luck and sorry for my spelling.
i have one of these akai 27 inch with dvd, i had a similar issue i found a power supply at auction and exchanged it and it works fine now, normally with this symptom your power supply is fualty. if the light goes green and you have no picture then you know other boards are fualty
i am having the same problem. My Phillips 37" 37PF9431D/37I LCD High Definition TV won;t turn on. When I press the power button i hear a click and the green light comes on for a couple of seconds and then the red light appears. I can;t figure it out. Did you find a solution?
Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.
If the light on the media reciever doesn't come on then the power supply in that needs to be replaced by a service tech. If you disconnect the 2 cables from the media reciever and the panel and then try to turn on the panel it should light with red and green squares for a few seconds but will turn off as it needs the media reciever to be connected.
