Sziasztok, a fenti LCD-ben a T-con panelen volt egy zárlatos smd kondi a VDA, ill. A VAA ágon (ugyanaz a táp kettös jelöléssel), ebböl adódóan, tönkrement néhány dolog, ami probléma számomra az az elégett QP7 tranzisztor kiléte. Ezek a tápok többek között a HX 8904 IC-ket látják el energiával, segítene az is ha erröl lenne egy adatlap, illetve a tápok értéke, addig nem akarnék kisérletezni. A T-con számai: V320B1-C, MS35-D004737, az agya CM 2673C-KQ. Köszönettel.: Imre ui.: képet tudok majd mellékelni a panelröl ha segít.
Üdv Kollégák!
A fenti kis tv /családi megkeresés/ táp javítása után már működik, csak a hangolás befejezésekor memorizálás után elhúz az AFT. A SM. szerint a T7-es mérőponton az L35 tekerccsel +2.5 V-ot kéne beállítani. Nem lehet, mert IC101 AFT bemenete /9-es láb/ beterhel. Felemelve a jó érték beállítható. A 9-es láb és föld között kb. 180 ohm-ot mérek. Az M37220M3-102FP IC-re gyanakszom /42 lábú SMD/. A szokásos szállítóknál nem kapható. Van-e valakinek bontott, vagy valami roncsban? A kis HQ-nál régebben L7-PAL néven is futott! Segítségeteket előre is köszönöm.
Üdv: K.Gyuri
Segítséget kérek a megnevezett tv. tápegység javításához.
Köszi:Taki
