Blank sa kaliwa ang kanang sides? Check mo muna refresh at resolution mo. Then setting adjustment ng monitor. Pero karaniwan na yatang sakit yan ng monitor, loskon.

Nadadala ba sa tapik sa gilid kung minsan?

update lng mga sis nag palit na ko ng ecaps, tip122 ganun parin. Nag roll tapos di po mabasa ung display parang raster lng kahit may signal galing cpu. Kapos sa horizontal size,,anu kaya possible problema nito.

AOC CRT Monitor 7vn (ata

) gamit ko sa hauz

no display, with power at pumapalo naman ang relay....endi ko po kabisado ang mga voltages sa f-back

tip naman mga master which part to suspect...may signal naman na na-dedetect since naka-on naman ang led kapag naka-power ang CPU. Kapag naka-off ang CPU blinking ang led (wala signal)
dati kapag nag-power minsan nag re-retrace (black horizontal line streaks sa screen na pasulpot sulpot) tama ba ako..

need your help folks...

thanks!

loskon yan sis, hula ko lang. kapatid yan minsan ng pincushion, tapos nagwawide tapos naelongate. Hanggang mawala na tulad ng ngayon sa iyo.

^thanks sis, nag try na ako mag re-solder dun sa mga suspected parts small transistors at mosfet, to date kapag i-power minsan labas agad ang display pero minsan naman balik uli sa dati symptom (blank screen) but after a while lalabas na display...minsan naman ayaw na

hmmm...me na-miss ba akong solder points

Baka meron naman component na corroded ang terminal lead. Sakin kasi tinuktok ko yung mga parte ng board kung san nawala nandun yung loskon. Di ko mahanap-hanap eh.

abeTIR · « **Reply #17 on:** February 05, 2012, 08:40:43 AM »

^hmm..that gave me an idea..masubok rin nga baka madale na..

thanks, sis
