Question about Philips Televison & Video
The repair did not fix it. it does the exact same thing when powered on. There is an immediate click from a small black box looking thing on the board (located near the fuse). when unplugged i hear a faint whining noise then another click.
It can be DC filters caps with leaking/bulging tops, or they have high ESR, bad transistors or IC or transformers in the backlight inverter circuits, bad lamps assemblies. Please read below and look at the pictures of bad caps, failed monitors, and troubleshooting guides.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

This is usually and most likely caused by the power inverter/board. There are capacitors and other components that can burn out and will cause the power not to be transfered correctly

Just replace the T-Con board and you dont need any soldering at all. JUst be careful for the flex connector.
