Re: le37r87bd help
OK, now remove the shield from the inverter board. That's the board the white and black cable goes into. Take good clear photos of it; if necessary, split the board into different photos.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: le37r87bd help
Set meter on 20000 ohms (20k ohms)
Test across points highlighted. Record reading and post here.
Repeat for all transformers on the board. Pins 5 to 8.
POWER TO INVERTER MUST BE OFF - UNPLUG TV!Attached FilesPlease do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: le37r87bd help
Yes - meter on 20000ohms must be inflation!!
the 2016 is just over 2000 so if this is the same would be off scale!

Re: le37r87bd help
The one which has been replaced you do not get any difference from probes not touching?
I would check it is soldered right - if so it might be a dodgy part or bad luck.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hi All
I have a problem with SSD on 820-3662-03.
Have tried to put in m.2 but still no ssd in disktool.
It works with external usb hd.
Maybe there is a problem with C3710 to C3717 on motherboard? (have seen it in another thread in this forum) but I cannot locate it on the board, so i can messure it.

Hi all, looking for some help with a Samsung LE37R87BD.
The TV set has no picture but does have sound. At first i thought the issue may be with the AV panel, but i've since replaced the supposed bad AV panel with one that i know is in full working order, and the problem persists.
