Oo sa power supply

thanks sa inyo tech at electron na maganda

Tech solve na yung Font nag nagdodouble, red saka balack pinalitan ko IC300 at ok na yung fonts nya hindi na naghahalo yung red at black. Tech yung IC101 KA2143 nakalagay sa service at KA2143B na nakalagay sa board ay iba sa nadownload natin dataset na ka2140. yung ka2140 ay may 28 pin samantalang yung ka2143 at ka2143b ay may 24 pin lang. saka mas malapad yung ka2140.

at may napansin rin ako sa ka2140 yung contrast at brightness ay handle nya. samantalang sa KA2143b ay hindi.

Tech yung Function na VIDEO CLAMP ng ic101 yun ba yung naghohold ng VIDEO?

Pasinya na if bumalik tayo sa topic ng IC101 kasi wala ako mahanap na sira

saka napansin ko kasi visually na yung paligid ng IC101 ay nagkulay darkbrown na parang bang meron burned na nangyari, don naman sa iba IC ng board ay wala ganun ako napapansin.

Thank sa inyo

IC101 KA2143B Datasheet download Here v
http://rapidshare.com/files/95797372/datasheet.pdf.html

Saka naghinala rin tayo nun na baka main problem nya ay nagpapalit ng resolution kaya parang nagshashake screen

Datasheet Note:
"The KA2143B is a very high frequency video amplifier
system with OSD interface intended to be used in Monitor
with high resolution up to 1024 ? 768. It contains 3 matched
R/G/B video Amplifiers with Blank signal and provides a
flexible interfacing to DC controlled adjustment system."

Tnx Tech Help me rin Electron Thanks

salamat naman at may nabago na , sana post mo rin ang magiging resulta hanggang sa mabuo

gusto pa sana kitang tulungan, kaya lang actual trouble shooting ang alam ko, yung mga terminology hindi namin napag-aralan ng husto, marami naman ditong tutulong sayo pagdating sa terminolgy. yung mga ini-explain ko sayo base yung sa sariling pag-aaral ko.(basa doon ,basa dito

)
ito baka makatulong
