Monitor goes black - green light stays on

My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.
  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

TV goes off suddenly. Searching for connection.

'Searching for connection' sounds like it's looking for a network link. check your internet connection. If it's supposed to be watching cable or broadcast TV, check the setup menu.

I do not see any reference on this problem and I even checked with Sony. If you are on a cable box, I suspect that is the problem.

Philips 27PS55S/121 sound level decreases

Yes, the dynamic range on DVD's is enough to cause the high and low passages to be somewhat annoying but, sounds more like a movie theater. This kind of dynamic range showed up first on Beta HiFi and VHS HiFi VCR's because of thier range as well. If there is a feature in your audio menus on your TV such as "audio expansion, SRS, Wide mode, etc." turn it off and let the audio be processed without expansion of any kind as that will amplify your dynamic range alot more. The lock up issue could be something Philips is aware about and if under warranty contact them. Otherwise not much you can do except manke sure the voltage going to the TV is failry stable between 110 volts and 120 volts. Sometimes dramatic drops and or increases can cause lock up or confusion to the microprocessor in the TV.
