Bonjour,

Je cherche la cause du Problème d'affichage LCD Sur une de mes Beolab3000.

Hello,

I am looking for the cause of the LCD display problem on one of my Beolab3000.

I have inverted the "Front Faces" and the conclusion is that the TWO full panels (LCD + its card) work well on the chassis which is OK

These cross trials drive me crazy !...  Especially, so close to the goal: RESTAURER Two beolab3000

Finally, I discovered that the voltage of 6.8V was not presented at the terminals of the diode D112 on the motherboard "1"

 

The capacitors have all been replaced on the two beolab3000

I checked the transistors and diodes BUT without ... Results

Someone on the forum could help me ???

 

j'ai interverti les "Faces Avant" et la conclusion est que les DEUX panneaux complet (LCD + sa carte) fonctionnent bien sur le châssis qui est OK

Ces essais croisés me rendent fou !

Surtout, si près du but : RESTAURER  Deux beolab3000

Pour finir, j'ai découvert Que la tension de 6,8V n'était pas présenté au bornes de la diode D112 sur la carte mère "1" 

Les condensateurs ont tous été remplacés sur les Deux beolab3000

J'ai controlé les transistors et Les diodes MAIS sans ... Résultats

Quelqu'un sur le forum pourrait m'aider ???
