Sziasztok. A fenti tipusu kászülék sortranz, és skszorozó csere után rendesen müködik, a gondom az hogy a képcső nagyon gyenge (AGGEAK220x32) a kérdésem az lenne milyen másik képcsővel lehetne helyetesiteni?
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

The screen is black ... and we notice from time to time (when the image is very brig.) some small part of image.
Very few dots.
I tested the G1 2X V, G2 5XX V, Heather - G and J Volts in the neck of Cinesc.
Power Supply I tested +A 115 V, +C 200 V , +B 12V, +M 19V

Sziasztok!
Lenne egy Grundig ST70-710-Tv-m. A hibajelenség a következő. Bekapcsolom majd ő kb 1-2 perc után kikapcsol magától. Megismétlem ezt a játékot egy párszor, majd ha bemelegedett gond nélkül működik,és nem kapcsol ki magától útána. Kondizás nem segített Szomorú Kérlek segítsetek mi lehet a baj.
Maradok tisztelettel: Korben
Szép estét mindenkinek. A címben szereplő lappal szerelt tv -hez kérnék egy kis segítséget.
Hibajelenség : Bekapcsolom stby van elindul majd leáll.
Feszek rendben vannak. Hátha már volt valakinek ehhez hasonló hibája. Szívesen fogadok bármilyen ötletet.
Köszönöm előre is mindenkinek a segítséget.
Üdv: András
