Help fix screen t.v.

I have a blank screen the red lights on but no activity

    Red light (below screen) stays red, but set won't turn on. It does blink quickly, when power button is depressed.

    I have the same problem: Set will remain in standby (red LED on) but will not power up either from remote or at the set (green LED flickers for a moment and then changes back to red.)

    The new AC adapter sounds like a likely fix, but can you confirm the dimensions of the plug? Most 12v/5a adapter plugs are described as 5.5mm x 2.5mm, not 2.1 mm.
    Thanks for the help!

What red light are you referring to? If you are talking about the red l-e-d power light beneath the screen, that is the power off light. If that red light light momentarily turns green and then immediately red again when you are attempting to turn the tv on, that indicates a bad power supply.

    The 12 volt power supply is bad. Go to ebay look for 120 volt ac input and 12 dc output @5 amps.
    The output plug is 5.5mm x 2.1mm in size. Look at polarity symbol to be sure the + is the center hole. They are about $16.00.

  • Jonny Pridgen Nov 03, 2008

    You are correct, it is indeed 2.5mm a .0157 thousandths of an inch difference.

  • Jonny Pridgen Nov 03, 2008

    ten thousandths, not thousandths or 16 thousandths rounded off.

My 42 inch philips (42PFP5532D) has blank screen but blue light to show its on but nothing on screen :(


just let me know if their is a sound when you turn on the tv then the only problem is black screen. if you can get sound tried to press the channel up/down button let see if you can get a channel. if you hear that receive channel that was mean the problem is either the screen back light get busted or the power inverter is defective. hope this can help good luck.
