Lg 42ln5300 led strips replace
Hello everyone.
I have a lg tv model 42ln5300 with black screen but with sound.
I noticed that the voltage going to led strips was too high according the specs.

So far was good.
The problem start when i put everything back panels, boards,etc)

Sharp led lc-40le653u no power
Hello everyone.
I need you value opinion.
I have a tv from a friend that fall to ground and now doesn't turn on.
So far i check the connections on ps and i get 19v on connector cn02 on pin 1,2. (this connector doesn't show standby pic)
on main board i have 5v present on connector coming from power button. But, as soon i pushed, voltage is not present on pin going to ps on/off.
So main board is bad???
Thanks...

Samsung un55h6203afxza us01 no backlight
Hello.
I need you value opinion on this case.
This tv show sound but not backlight or video.
The original ps show really on led drivers connector high value on m1+ but almost 0v on m2+,m3+,m4+ and m5+
that make to take the decision replace not only ps if not the all kit include ps, main board and t-con board.
But still show the same symptoms.
No backlight, no video but sound ok.
The connections on ms1 still remain on 280v-320v fluctuating and another m+ remain 0v.
What i doing wrong or new ps is bad?
