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?

Thank you for your comments, info.

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

Sziasztok ! Tartalmat keresek a fenti TV-hez . / MDA lakik benne / Előre is köszönöm !
Sziasztok!
Hozzám került ez a tévé, számomra rejtélyes hibával. Bekapcsolást követően a bal fölső sarokban megjelenő kiírás: gomb---
Sámokkal próbálva csak a --- változik ///-re. Elmondás szerint valamit lehet elnyomogattak rajta... Na de mit? Olyan mintha pl. szervíz menüben lenne vagy ilyesmi.
Ha lenne valakinek ötlete/tanácsa/konkrét tudása a dologról, megköszönném.
Köszönettel: Kiss Z.
Sziasztok
Hozzám került egy GRUNDIG STS55-1001/7-es T2S08(00) alaplappal szerelt Tv.
A hibajelenség a következő:-tv bekapcsol,nagyfesz,fűtés,tápfeszek felállnak.Képernyő sötét,hang nincs.AV-hang van kép nincs.Segédrácsot feltekerve visszafutási csík. STV2248H cserélve. Azt mondta az "ügyfél",hogy menetközben kattant egyet,majd se kép se hang. A segítséget és az észrevételeket előre is köszönöm.
