Hi,


Let me be on point. The generic solution would be Lamp ( If it's more than one year ).

Friend the easiest way to tell, would be to pull lamp out close door tightly turn unit on listen for the ballast to make the buzzing noise if it does it completed its cycle and you just have a bad bulb that looks good. And also do this test Were the wire is that runs from the ballast to the power supply, make sure it reads around 300vdc if it doesn't you need a power supply if it does you need A BALLAST. You can make sure the capacitors close to the connector are flat on the top if not you may have bad capacitors.

The pictures of Ballast :-

The pictures of Capacitors :-

http://images.google.com/images?gbv=2&hl=en&sa=1&q=electrolitic+capacitors&aq=f&oq=&aqi=g-sx1&start=0

If not,

A POP from the TV could be just about anything. Sometimes capacitors swell up and burst. Most likely you are dealing with a shorted IC, from the churping sound I can tell that the switch-mode power supply is over-loaded.

From the sound of your problem you should probably call for service. There are too many variables involved to diagnose a problem such as yours over the internet. Modern TV's have thousands of parts, it can take a seasoned veteran up to an entire day to track down troublesome problems IN PERSON.


Please understand that by opening a TV you are exposing youself to many dangers, including electrocution. Be sure that the set is un-plugged and keep one hand behind your back whenever possible to avoid a shock through the heart as this CAN KILL YOU. If you have zero electronic experience I would not attemp this repair. OK, public service announcement over.

Basic electrical knowledge is a must to get inside your TV and fix it.

Your TV will need some parts and it is best to either leave it to a technician to diagnose.

If you call for service prepare to part with $200-$350 depending on the damage in the TV. It may be prudent to buy a new TV if this one is over 7 years old.

Let me know if need further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Oops!!

    I did not read the comments so i was not aware that this is not a PROJECTION TV.

    For your model,

    The TV not starting properly you should hear the tone noise (bleep bleep) not a ticking noise or no sound.
    A long time coming on is a classic example of what I am detailing for you below. .
    These LCD's have problems with the power supply capacitors going bad,
    a servicer will charge between $200 and $450 to repair it replacing
    either the capacitors or the whole board.
    here is a DIY (do it yourself) solution:
    It
    could be just a few bad capacitors on the power supply, if you want to
    attempt the repair yourself you can do a visual of the power board caps
    will appear swollen on top.
    We do not recommend do it yourself, but depending on your knowledge and technical ability you may be able to.With
    the back removed you will usually see two circuit boards the upper one
    is the power supply, it has a few capacitors on it (cylindrical
    standing straight up soldered in mark on the sides with the
    positive/negative sides and MF and Volts values.

    The
    power board and back unscrew with a medium philips screwdriver, if you
    do not know how to desolder and resolder then do not attempt this as
    you may damage the TV more than fix it.
    I am posting a photo link of some swollen caps on a board so you know what they look like here.


    Hope i helped you.

    Thanks.

Power light but no picture or sound


Hi!
My name is Chris.
I have this Phillips Wide Screen TV that didn't have or come with a remote, so I had to go out and buy a universal remote for it today from a BIG W Store. I'm having some technical difficulties & problems with switching and turning it on, but as I use the universal remote to turn on the TV, I'm having a bit of a slight problem with it turning it on, Ok, Yes, it works and Powers on, but there is nothing showing or giving me the indication that there is no picture or sound showing up on this Wide Screen Phillips TV, But there is a little red & green light at the bottome right hand corner that keeps on flashing red when ever I use the universal remote to switch the power on. Is there a possibility, that i can get some help on here, to help me out with any suggestions, is to why I'm not getting any picture or sound showing up on this TV with this universal remote ? Is there anyway that i can maybe get some help with this to help me out with solving my issue with the Phillips Wide Screen TV ?

Your set is still under a manufacturer warranty. Take your set back to Wal-Mart and they will send it out to be repaired, or give you a new one.

Samsung TV stopped displaying picture


No picture but sound can mainly be of two problems, most of the times it is caused by a faulty vertical deflection ic, you can diagnose this by slightly increasing the screen voltage by turning the screen control on the LOT, a horizontal line will appear if the vertical ic is shot, and the other problem is the CRT base, but this is less common for shot base won't go off at once, it will show picture faded in the beginning. Now another problem could be the horizontal output transistor, if the tv has a high power sound output, the sound power supply will come from smps itself instead of from LOT, check that too, to confirm this, check if the CRT filament is glowing. Good luck.
