Re: Grundig 40VLE7131BF led strips doesn't light up



Hello everyone,
Just an update regarding led strips.
After replacing led strips TV started working correctly.
Thanks for helping me....

Hi guys,
I have one very old TV.
Main problem I have with this tv is that led strips won't light.
I measured voltage levels, and inverter input is 24V.
other voltages are also ok.
What I found is that removing and connecting again connector CN1 led strips lights for shorts time (but only once). When led strips lights up then light is uniformly spread on whole panel.
First I thought that led strips are dead, but I'm quite sure that problem is not strips related.
I don't know what voltage level is at output of inverter board (samsung SSL400_3E2A) and how...

Re: Samsung SyncMaster 720N - power LED blinks



Hi,
same situation here.
Power led slow blinking and won't turn on.
All capacitor look good, but I suspect to Video board.
Connect ON/OFF pin to 5V and backlight turn on, but blinking just like pwer led does, 5V voltage are stable, but on video board that voltage change its value from 5V to few mV, it seems that some kind of short circuit is there...
Now I'm trying to find what cause that situation...still not done replace capacitor on video board.
Any sugestions?
Do I go to...
