pag-on ng tv,mga ilan lang na segundo maybe 10 second ay lakas init agad ,me pansin ako sa vertical picture nya, me mga horizontal line na visible,marami,mula taas pababa.parang me interference na pumapasok.napalitan ko na halos lahat ng filter cap.nya sa vertical ckt.ganun pa rin.pagpinatagal kong paandarin ang unit ay baka sumabog uli ang vert,IC.nagpalit na rin ako ng good na yoke,ganun parin. salamt pala sa responce nyo.malaking tulong eto sa akin.

how about sa ibang peripheral parts nya resist at mylar caps ?
kng ngawa mu na rin yan at
based on your statement di na nga yan normal..
pwde def yoke na nga yan masxadong mabigat.. "out of torealable value..

o kung ok lng sau.. pwde mung dagdagan ang heatsink mu sa vertical ic.. bka mkatulong ng kunti.. kng my scope ka sana mas mamomonitor mu ang behavior ng vertcal sweep

bka nag-adjust ka sa flyback kya may mga lumabas na mga horizontal line mula taas hanggang baba. focus ka sa supply ng vertical bka ndi tama.
