the fact that unit is nor working after a lightning strike means that all that you have done is to no avail and it will co9st more to continue with repairs than to replace the unit use a quality power surge protector next time

www. shopijimmy.com put in the model of the unit

What your describing is symptoms of a power surge, Many LCD Tv's are sensative to Slight fluctuation in power during rain, thunder and lightning storms, i myself was happily watching Tv through such a storm at one time, and when i went to bed the TV would not respond remotely or manually, i also disconnected the power from the wall waited for the ready light to disolve and try to turn on, unfortunatley the damage was done, a Tv Repair was nessecary and since then i now use a belkin power surge protector board for my TV and appliances......one question to you is i would guarantee you do not use a surge protection my friend......and your set will need a Tv Repair, it is not major as what is neccesary is a firmware dump on the internal memory and replace the BIOS Battery as well.

A popping sound as you describe sounds as if your tv blew a couple capicators on the main control board. More than likely , you are needing to aquire a new main circuit board.

T-con or display or main

Hi Billy Will you please upload a picture of the screen to your TV? The description you've provided here is too difficult to get. Gopakumar Gopalan Google

www.samsung.com. You can download it from there. Look for support.

FIXED!!..I had the same problem. Power board looked fine (not blown capacitors) It started after a moving...it was just faulty (loose) connectors from the powerboard to the mainboard..... I just unplugged and plugged them back firmly.

Sounds like a bad capacitor in power supply

Most likely your power supply is defective. I would suggest you check the fuse on the power board. If it is blown, you have a problem with the power supply

Three thoughts---check for short to ground with fuse removed and power off (unplugged) on both sides of fuse.Use a original type fuse---generic ones often blow for no reason.Consider replacing the board if you can confirm issue is on it.

My tv too

First if you are able is to examine the power board---look for any signs of damage or puffed up filter caps..........

What is the problem with the remote? on this page press the "make a comment" and let me know what is or is not happening.

If all pictures including the menus appear in double than most likely your T-con board or T-concable are defective. The T-con is located on the upper portion of the rear of the LCD panel itself. Here is a link where the board and the cable can be purchased. Note there are a few different versions of the T-con board and they wil not cross with each other. There is a bar code on the T-con board with numbers that corralate with the correct part number. Follow that before ordereing : )

I have the same issue. Did you ever find out how to fix this problem.
Thanks,

You will not have any luck, The Screen only uses RF for control. As far as I know there is no IR receiver on the unit or any RS232!! A nightmare for integrating this product into universal control systems.

You are dealing with a failing backlight inverter. You are hearing the surface mount components failing over time and that buzz is them not keeping up with the voltage coming into them. (Hz) You will need to open the tv and locate the noise and replace the backlight inverter :)


Please rate if this helped :D
