Likely power supply failure. This could be on a separate board that can be removed and repaired or replaced. Look for a smaller board with larger components that look like transformers and accepts the incoming AC line.

How do I tell which Philips flat screen I have


Well, personally I would say it is not worth fixing. The typical life span on flat panel TV's is about 5 to 7 years. Your set is close to the end of it's life cycle. Secondly, most experts recommend replacing your set if the cost of repair exceeds half of the cost to replace the set. By the time you pay the diagnosis fee, part cost, and labor cost, I think you will see what I'm talking about.

How can I reset my Philips 37 in flat screen TV back to the factory settings?


Hello,


You haven't mentioned the model no. of your TV. Nonetheless, the reset procedure for the model nos. 42PFL7409/98 / 42PFL7409S/98 goes like this:

1- Press Home,
2- Select [Setup] > [Installation] > [Factory
settings],
3- Press play to enter the [Factory settings]
menu
[Reset] is highlighted,
4- Press OK to reset to default settings.
5- Press Home to exit.
The reset procedure may differ for other model nos.

Furthermore, Press the "Menu" button to access the menu, and select "TV Settings" and then "Picture" to bring up the picture settings. Adjust the color, brightness, sharpness and other settings if the picture seems off. Select "Dynamic Contrast" to have the contrast adjust to screen changes and "Digital Noise Reduction" to cut down on outside interference and reduce noise in the signal. On the "Installation" menu, select "Reset AV Settings" to have the settings reset to their factory defaults.

I hope the above helps.

Good luck.

I have no idea about where to get repairs as I don't live there but it sounds like you have a bad power board and it could be repaired yourself if you took the back off and got the part number off the board and ordered a new one. Please be a little careful when removing your board as if its been plugged in recently the capacitor on the hot side of the board can hold over 100 volts for awhile.

Laptop wont turn on philips freevents x51


The most likely problem is that your Hard Drive has Died.

If you can readily access another Laptop HDD, try it and see.

Other than that, I'd say the Motherboard has decieded to give up the Ghost.

Just Remember, A Laptops life expectancy is 3 years, after that you are treading on thin ice keeping Important Documents on it.
