Samsung 52 in. Flat-Panel LCD HDTV Questions & Answers
We had a power surge
hi,
IF you want to DIY the repair of your TV you should first know how to use a multimeter..specially voltage reading and resistance reading...
We have to find out first if the voltage output of the power supply of your TV is complete.There are 3 voltages on the power supply output section..they are as follows.
1) 5 volts---this voltage is the supply of the main boards CPU without this voltage the system will be dead.
2) 12 v --this is for the audio amplifier section the sound of the TV.
3) 24 V --This voltage is for the supply input of the inverter board.inverter board is a board that gives a supply voltage to the back light lamp.the input voltage of the inverter board is 24 volts and convert it into a high voltage volts enough to light up the screen of the display monitor.
There is a fuse that on the power board check them with your tester if the fuses are bad or good and replace it ..
check the power supply first and post back for the findings you have...good luck!
Keeps turning itself off.
Check the power supply board for overheated, bulging components, esp. the can capacitors. Replace with similar or higher rating caps you can order on the net. Hope this helps you.

HI:
Check Inverter board for buldging capacitors also there are two of them on the inverter that like to go faulty causing low lighting on one side. Its also a good tool to retrace you steps and open the unit and check all cabling and connectors especailly the LDVS runing between the T-CON Board and the Main digital board.

Hello,
There seem to be a problem inside the unit that is why it keeps going off and on.
This problem can be caused either by power or by the lamp.
If the lamp of the television is faulty, then the lamp will be causing the television to trip off and on continuously.
The solution to that is for you to unplug the television, leave it for about 2 hours so the high voltage will dissipate, then you unscrew it open form the back, take off the back cover and assess the lamp of the television, once you find the lamp looking burnt, then you need to replace it, by carefully applying a little force then pulling it out and fixing a new one in.
If it is the power, all you need to do is to assess the main board and the power panel for any bad capacitor, if it looks compressed, swollen or burnt, then it needs to be replaced.
Also on the board, try to look for any part where lead melts off and causing a bridge of two capacitors on the board and correct it usind a soldering iron.
Take care and good luck
I hope this is helpful.
TV CLICK WHEN TURN ON
I had the same problem. http://www.youtube.com/watch?v=tK7zFBBU6p4&feature=related The click click sound was my clue - its a common problem with Samsung. I watched a few of these and was able to see the 4 bad capacitors on my tv, de-soldered and replaced them for under $5.00.
Hope this helps. I have never soldered other than a couple of wires on a speaker; so this required some practice. Disconnect the TV for a couple of days to make sure the power down the unit before you touch the inside of the set.

If your using the IR remote, the actual colors of the tv are what is causing your problem. What I have found to solve this is go to your local ATT corp. store and order the RF remote this will solve your problem. The techs don't carry these on their truck.

Tv won't turn on
It has bad power supply(capacitors bulged), and possible main board bad ,too.
TV isslow to turn on.
Hi,
Clicking Sound and other Details you provided indicates a Problem with Power Supply Board.
You need to Open the TV. Make sure it would be
Unplugged. You need to Take all the Precautions. Locate the Power Supply
Board. Remove the Connectors and Pull out the Board. Once you Pull out
the Board, with the Help of Magnifying Glass, locate Cold Solder Joint.
If Everything is OK, then you would Locate Bulged / Leaked / Swelled
Caps. They would have Ammonia kind of Odor. You need to De-Solder them.
You could take the same to Radio Shack / Fry's / Order Online. Once you
get the New Caps, Solder them and it is all set.You also need to Check
Fuses around that.
Let me know, if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
Avol ALT42FD120 - frame rate change 60-120hz?
Hi. It is entirely possible that the set is already running at 120Hz after all. The display 1080p 60Hz is merely the signal it is receiving and the earlier TV's that used to claim 100Hz/120Hz merely did so using line doubling only to give a clearer picture by filling in the blanks between scanlines. If your picture is already very clear, then I wouldn't worry about it
I have a LN52A650A1F with
This is a 2008 model. The real problems you have is that the panel is expensive:
Description
LCD-PANEL;LTF520HE01
List
$939.40and it has a 500 dollar core value--if the one in the set is damaged you do not have a core--add 500 to your cost. There is one other issue here that many people do not consider; if the set was on when the damage happened or turned on after it happened any board in the set may now also be bad--like running a car with no oil in the engine. Usually when you have a damaged panel in a LCD or PLASMA set it is not worth fixing. SD TECH
