POLYTRON MA 20306FX NO DISPLAY

Post by mannydioneda on Sat Jan 12, 2013 6:51 pm

Happy New Year!

Patulong ulit sa inyo mga master. No Display ang status, pero bago mag no display ay may guhit sa gitna (vertical line) at black sa magkabilang tabi.

Master Ultra, kanina habang check ko voltage ng b+ ay nagkaroon na ulit ng display at okay na hanggang ngayon. Nangyari na ito dati at nag no display pero after ilang days na hindi ginagamit ay ng i try ulit namin ay okay na ulit. Ano kaya dahilan bakit nagkakaganun?

gud am, bumigay na ulit ang yunit, no raster with power ang status, may pinalitan na akong ecaps sa horizontal section ganun parin at walang filament. Kung good pa ang HOT niya ibig bang sabihin okay parin ang flyback? May nagsabi sa akin na baka yun Jungle IC na ang sira.
