Va salut domnilor, vreau sa comand un tester led si as dori sa stiu si parerea celor care folositi deja acest aparat. Mi-au atras atentia doua modele si anume :

 

0-300V LED LCD TV Backlight Tester Meter Tool Lamp Bead Board Detect Repair Tool _ eBay.htmlLED Display Screen AC 220V With Light Backlight LCD Tester Bead Board Lamp.html

 

As dori sa stiu si parerea dvs.

Multumesc, o seara placuta.

primul link de la tine este tocmai cel din linkul prezentat de Florin = GJ2C

ptr 90% din cazuri e ok testerul

aprinde insa si led-uri care sunt la limita si in tv blocheaza backlight-ul

in aceste cazuri trebuie urmarit si cum se aprind led-urile ( se aprind progresiv , nu brusc ) pentru a interpreta care led ar putea fi de vina

apoi testat acel led cu o alta sursa de curent constant care se poate regla manual
