Tisztelt Fórumlakók !
A címbeli tv-vel és hibával kérek segítséget. Az alaplapon (TNPH1160 1A ) a feszültségek jónak tűnnek, a táp (TNPA6263 1P ) kapja a Power ON, Sub ON, BL ON; +5, +16 leadja, de a világítás nem megy, BL SOS vonalon 0V (ha leakasztom, alaplap felől van 3V3.Sem zöld, sem piros LED meg sem nyikkan.Táp erőltetett indítással megy, világítás is, de néhány másodperc után elkezd villogni 1-2 másodpercenként. A világítás ( 2 X 4 LED csík) az egyik csatlakozón megadja a 164V, de a másikon csak a 65V marad, ott a FET nem kap semmit a G-re. Ha felcserélem a 2 LED csík csoportot, akkor is ugyan azon a kimeneten marad a 65V. IC (BD9483F) csere nem segített. Itt arra következtettem, hogy a LEDek jók lehetnek, és a lapon lesz a baj, de mi van az alaplappal? Kérdésem az lenne hogy ezeknél a Panasonic-oknál van olyan (mint egyes másikaknál) hogy a világítás hiba miatt az alaplap nem ad életjeleket?
Köszönöm ,
Tisztelettel,

Sziasztok, a fenti LCD (ch.: GLP 24), bekapcsoláskor megjön a kép majd néhány mp. múlva el is megy, villogó piros marad a led. Táp, inverter átnézve, kondik mérve jók, ill. próbálva. Ebben külön van a táp és az inverter, (inv.: KLS-EE32PIH12M), háttérvil. jó. Esetleg egy rajz is jól jönne ezekről. Ebben kérnék segítséget, köszönettel.: Imre
Hi
I am having trouble finding any information regarding this product.
The unit powers up and the output is displayed on the screen for between 0 and ten seconds, the unit then powers down, the red standby LED on the front of the unit blinks then remains off for 5 seconds then blinks again.
This cycle continues until the power is disconnected, if the power is reconnected the unit goes back in to stand by (red led steady) it will then power on again.
Also in the error mode (red led blinking) and the power button on the back of the unit is pressed twice it will power up but this does not happen if the remote is used.
I have tested various capacitors and diodes but all seems well, I have also replaced the power supply with a reconditioned unit but this has not helped.
I have been unable to obtain any service information for this product.
So any input would be most helpful.
Thank you
Stephen Fry
