Sziasztok!A fenti tv-nek csak fél képe van.Lehet T-CON hiba?Kép mellékelve.A T-CON típusa 6870C-0368A VER V0.6
Üdv
A fenti készülék röpteti a TDA8350Q tip. eltérítő IC -t.
Az r55006 poz. számú ellenállás 5R6 lefüstöl az ic jól mérhetően zárlatos lesz.
Kondikat ,diódákat stb ellenőriztem .Látszólag minden hibátlan.
Az utolsó IC-met nem szeretném röptetni.Hálás lennék mindedn ötletért.
Köszönettel:töröká
Sziasztok.
Szeretnék egy kis segítséget kérni.Van egy Grundig tv,ami kb 10-15 perc működés után kikapcsol,és készenléttibe marad.Vissza lehet kapcsolni,de ugyan ezt csinálja.
Kérem,ha van valakinek ötlete,nagyon megköszönném.Üdv:Suhajda István
Sziasztok.
A TV eddig ment,most ujra ez a hibájja.
Hiába forrasztom át,10 perc mulva kikapcsol.
UPDATE:
Note: This Model and CUC220, CUC720 almost identical
My family b. this TV in 80'
And worked ~15 years
In 90' Black screen ... with Pot. in 100% Brightness, Contrast.
In the end 90' puff doesn't work at all.
Someone try repair but ... the same black screen.
They reported ... try fix and get > Brightness
In past 6 months, I repaired and new life come from the set, but now we get too much Brightness
In your opinion ... the person try Adjust ... fix what?
ABL - Automatic Brightness Limiter setup, regul.?
R2533 R2538?
Thank you for your comments, info.
Ruy
Please your comments:
Brightness and Colour Pot. -> OK
But Contrast Pot.: I can' rise ... NO FOCUS and
washed out -> I only see a Blank RASTER.
Best Regards,
Ruy

Very few dots.
