Hi,
I have a samsung tv (2009, works well) apart from an imminent flickering issue for some time.
Model: LA46B550K1R
Model code : LA46B550K1RLXL
Ac:100-260 V 50-60Hz, 240W
Power supply circuit: BN44-00265B
I read through the forums and found other Samsung models both 46, 55 inches , old and new with similar issues. Two things stood out:
1. eco setting in tv was recommended to be switched off
2. Jumper number JP852 was recommended to be cut off.
Now before opening the tv i tried playing around with the backlight since eco setting was already turned off for me. I must say at this moment that everything else in the tv works fine apart from the flickering(intermittent).
So i reduced the backlight from 9 to a 5 and also performed a reset in the settings (reset also puts it back to 5). This stopped the flickering for close to 24 hrs. When i switched on the tv today, i found this issue again while watching , intermittent. So it flicks for a few minutes and then goes away, back to normal.
So i gave in and thought of opening the tv unit (to solve the problem once and for all) and locating the jumper above. Now, nowhere is my model number or power supply circuit number(both mentioned above) mentioned in the forums , hence the jumper jp852 was not found in the same location as in the videos or diagrams.
I shall attach pictures of the board herewith. So after a while i located the jp582 but it is next to the two black capacitors on bottom right. Where it says 46 inches, i was confused as there were many JP numbers.
1. So my query is which jumper should i cut so that this flickering stops.
I presume this particular tv model might use a different jumper number than the 582 for the said function. I may mot be able to replace the resistors so while i know this “cutting” will play withe protection circuit, i am ok to go ahead provided i am sure that i am cutting the right jumper.
2. Also, what are the risks i am undertaking while doing this from a protection point of view?
Plz help as i have opened the tv and would like to solve this today itself.
Many Thanks
