04 / 06NASIL İLERLİYOR
- 1Panel sökümü ve LED teşhisi
- 2LED bar / sürücü onarımı
- 3Uzun süreli görüntü testi
BELİRTİLER
- Ses var görüntü yok
- Çok karanlık görüntü
- Bölgesel kararma
- Açılıp birkaç saniye sonra kararıyor
BEKLETİRSEN NE OLUR
Tek LED'in yanması çevresindeki LED'lerin yükünü artırır; bölgesel kararma zamanla tüm ekrana yayılır. Erken bakılırsa onarım daha az parçayla biter.
SIK SORULANLAR
TV'nin sesi geliyor ama görüntü yok, sorun ne?
Bu, çoğu zaman panel aydınlatmasının (backlight) arızalandığını gösterir. Karanlık ekrana fenerle yakından bakınca görüntü seçiliyorsa ihtimal daha da artar.
Backlight onarımı paneli değiştirmek mi demek?
Hayır; panel sağlam kalır, arkasındaki LED bar ya da sürücü devresi onarılır.
Onarım sonrası görüntü kalitesi düşer mi?
Modeline uygun LED bar kullanılır ve teslimden önce görüntü uzun süre test edilir.
