Then i think the capacitors is bad in power board

Posted on Jun 18, 2008

  • dewan nafees ahmed Jun 18, 2008

    it would cost $760 to fix

    there are 2 boards, one is a power supply and other is control board

    The board is supposed to cost $550 and then $210 labor to fix the power supply and install the new part

    power surge due to high voltage could have damaged ur boards,

    use a voltage regulator box to prevent this in future.

  • dewan nafees ahmed Jun 18, 2008

    sorry it was not control board

    it is LOGIC BOARD , X and Y SUSTAINERS.
    their life is only around 7 years. there is several different circuits in the tv that can cause this problem.

    and so i have mentioned u almost all the possible problems.

    thank you

    dont forget to accept the solution if u go by it.

    good luck

    have a good day

Hi my recently we had a lightnight strike


Hi Kayal,
This kind of problems occur after lightening. I am sorry you can not do anything about it yourself. You will have to consult a good local TV Tech.

I have a panosonic plasma 42 inch tv. After a storm all I get when I turn it on is black and white static but all the menus display fine


Look to see if the rear video/audio inputs work (DVD etc) and if they do the damage is at the tuner in the set (nearby lightening can discharge into the cable or wires for signal.)

If using a box (cable or satellite) it may have took the hit.

A good idea if lightening storm is to not only unplug set (static discharge can come in via the power cord also) but disconnect signal source from set.

I have in extreme cases seen a nearby strike get in via the power lines and destroy almost every appliance plugged in even if not on.

Tv picture flashes off and on


Just check whether the power outlet is ok, by connecting the TV to a different power outlet. If it does not work, this could be a defect due to dry solder/component failure in the PCB. This may need attention by a qualified service technician.

Bad storm, lightening strike outside then TV went off and will not come back on.


I would start with your power supply. If you took a surge it is possible that you only blew a fuse. If it is a blown fuse, make sure you only use the same type fuse.

Hello, I jave a phillips ambilight I brought from best buy three years ago that stopped working. The sound comes on but there is no picture. Should I toss it or is there a cheap solution to the problem....


from the short diagnostic/symptoms description, I would hazzard a guess that the power to the lighting systems section is the culprit. I base this just on your statement that there is a total absence of picture/light thus indicating either a total light failure at the exact same moment ( highly unlikely, except as result of a severe voltage spike or lightening strike ). More common in this situation is, power to the lighting system has failed. Diagnostics to gain the exact cause should not be that expensive. But with technicians, just like plumbers, choose someone you trust with a good reputation for diagnostics ( Not a limited parts changer ).

Sincerely,

Poor reception on one tv channel only rest are fine


If OTA, check that your antenna is pointing at the station's transmitter. Look at antennaweb.org or tvfool.com (antennaweb is very conservative with the stations that it will suggest that you can get. Both assume external antennas.) If you have an amplifier, check if it is working (I lost a local VHF channel recently when the antenna splitter/amplifier got a power surge after a lightning strike - despite it being the nearest station.)

Consider resetting the tv to the defaults and rescanning for channels. (The reset is under Menu > Picture Settings > Advanced Settings (if you use Customized Picture Mode; there is a second reset under Audio settings for those customized functions.)

I hope this helps.

Bright white screen with faint images


If lighting did strike, you would be suffering power supply problems, due to a power surge from the strike.
The problem sounds like it could be related to the LCD panel becoming faulty or if your able to test inside the unit with a multimeter, you can measure the voltages from the printed circuit boards, especisly those suppling power to the LCD panel as well as the Logic PCB, A small printed circuit board you will find either attatched to the LCD panel. I hope this helps.
Good luck.
