Thank you for the question and your patience. Should you still need assistance...

Consider an experiment. Power on the TV and set to a program/channel. If at all possible, darken the room where the TV is. Shine a strong flashlight at an angle (not directly) and nearly touching the screen where the volume level / menu display is usually seen. Press the VOL UP/DOWN or MENU button and note if a dark/ghostly image of the volume level or MENU could be seen.

Postback results.

The above is a test to determine if it is a backlighting issue.

The Philips LCD TV would have to be opened up for diagnosis and to effect repairs. Depending on the model, checks/suspects would be:
  • LCD panel itself (least likely and hopefully not);
  • power supply (likely);
  • inverters (most likely).

Options then are:
  • consider a DIY (do-it-yourself) repair if and only if comfortable working with electronic components & circuitry, use of a DVM/VOM, a soldering iron/station and safe practices with electrically powered devices. Access to a Service Manual or at the very least, a schematic diagram would be a necessity;
  • should you be uncomfortable with a DIY, perhaps your best bet would then be to consult with and/or seek the services of an authorized Service Center (specially if still under some form of extended warranty) or a qualified professional;
  • evaluate other options considering cost of repair, down time, cost of shipping, parts availability and comparable prices of newer/better models.

Are you considering a DIY approach?
