Sziasztok!
Van itt egy 4 eves VIVAX TV-2908PF (68cm-es kinai tv, chassis PH02), sorkimenoje: BSC25-N0707, HR megfeleloje: HR80365.
Na most az a gond hogy nem lehet beszerezni, a TV mukodik de csapkod at a szikra a kaszkad reszebol a 1.5cm-re levo tap hutolemezere, es amikor mar sokat csapkod akkor kiegeti a biztositekot.
Van egy hajszalvekony 5mm-es repedes rajta, mivel lehetne leszigetölni, ha ez egyaltalan löhetséges?
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.

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
