FAULT: The plasma display shows no picture or the picture has significant maldischarge. Maldischarge includes unlit patches of display, overly bright parts, sparkling/unstable pixels or unlit pixels on colour bands.
DIAGNOSIS: Requires an oscilloscope. Should check Y-main waveform (was only about 20Vp-p when I checked it, should be >400Vp-p)
FIX: Replace 100uF 50V cap near yellow trafo on Y-main board
--Also encountered this fault with same model--

Sziasztok!
A tárgybeli laposhoz keresnék HIU813S inverter modult vagy BD9897FS kontrol IC-t.
Ebben zárlatos lett az 1. csatorna kimenet.Újjal nem igazán szeretnék kisérletezni,bár a FET-ek jók.Lehet hogy csak megfőtt az IC.Ha valakinek lenne eladó,kérem jelezze.Köszi.Üdv:selindion
Sziasztok!
Elakadtam a fenti TV készülék tápegységének javítása közben. A következő félvezetők beszerzésére nem találok forrást. Ehhez kérnék segítséget és/vagy a helyettesítésükre ötletet. Ami tönkrement: 2sk2717 (Toshiba gy.) ezt sikerült beszereznem, 2sk2917 (Toshiba gy.) ez nincs, FMDG 26 (teljesítmény dióda) ez sincs.
Köszi, Bagoly69.
Sziasztok!
A fenti plazma tv a képen látható hibajelenséget produkálja.
Külső jelforrásról (DVD, Video, PC) tökéletes a képe.
Antenna bemenetnél ferdén csíkos a kép.
Nincs semmi tippem mit cseréljek először, mi okozhatja ezt.
Üdv.
Miki
