Should be a back-light problem itself. If you wish to know more about the back-light system of this Philips TV, check this link. Pull up older posts there, either by its left side bar, or see it in Timslide option.

I have 3 flashing red lights on my 42" philips ambilight tv


Your power supply board is not yet dead, You know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

Hope this will help in solving the problem....

I have a Philips Ambilight 32 PFL 7623D model and the bulbs on one side of the tv are no longer working. Are they easy to get a replacement and if so where from and approximately how much??

It is unlikely that all the bulbs have failed at once and more likely that the ballast unit for that side has failed.
If they are available as a spare part they will be listed on ebay as the bakkast unit for your model/size TV or on the manufacturers web site through an authorized repair centre.
Hope that helps.

I have a philips 42PF9641D/10 and the ambilight on the left side will not come on (lcd tv) any ideas? On turning on the TV both ambilights came on then the left side went off after about a minute!

probably you got a processing unit problem, which makes your tv stopping recognizing the screen information .
you should try resetting all factory default settings, if this doesn't work, you will have to take the TV to an assistance center .
