Sir olibird mga intermitent problems yan a... pag tinatapik nyo nagnonormal minsan.
Tulad ng advice ni sir vhinz kadalasan may loose yan.
Dont rely sa visual lang sa pagcheck kung may loose solder... magresolder ka para sure..
Sa monitor A ilan tact switch napalitan? Recheck mo yung iba pa. Try also to substtitute ung AC cord baka nagloloose sa loob kaya kung minsan nag ooff na lang. Baka pagtest mo continuity e ayos pero pag nagload na naghhigh resistence na o nag oopen ung linya.
Sa monitor B try to recheck VGA cable.
Post ka uli ....

try first aid muna sir ... resolder ka muna kasi base sa sinabi mo na pag may ginalaw ka e nagiging OK naman.... the possibility is may loose solder na yan so again resolder muna. agree ako sir pete coldsold parin yan resolder mo pati resistor na malalaki pati FBT at chopper sama mo na check din kong may sira nang capacitor

Resoldered today, pati sa mnga wire na nakkabit sa pcb ng crt, db15 vga wire, tried also malaking resistor sa bandang psu, pti fbt, ganun parin...
Kinalas ko ulit pcb sa neck ng crt, tinangal ko na talaga yung plastic dun yung plug ng pins sa crt, hinigpitan ko terminal isa-isa para my contact sa lahat ng pins,,,
kso pg balik ko lahat2x test na wala na ako makitang display, khit yung ng sshrink na screen, pansin ko na wala na ilaw yung pahitan ng pcb at crt yung mismong tube sa neck wala na yung ilaw dun dati myron panaman wala nang lamp yung crt,
ok panaman yung pilot light sa harap ng monitor ok pa naman pgne off/on ko yung tactile switch sa harap, my bad guys lalong lumala ata, check ko ulit sa pins ng crt to pcb yung plug na ginalaw ko, patay ako nito wala na ako pera png repair huhuh salamat sa mnga replys bro,

sir double check nyo dinaanan nyo... ang possibility baka may napagdikit kayo sa pagresolder or sa pagbalik nyo sa crt socket baka may mga naputol na wires.

corrected na po yung ng sshrink, display & di lalabas yung menu settings dhil sa cold solder lng pala,, isang prob ko lng
Sa socket, ng oOn nmn kso super bright na yung screen display halos puti na my diagonal lines, pg galaw ko yung pcb sa neck ng crt mkaka chempo, kung palitan ko kaya socket nito ma cocorect po kaya? Alam ko mahigpit na yung mnga pins sa socket kinalas ko kse to at pinihitan, lam ko my contact na mnga ito.
B4 namumuti screen ko, nabalik ko yung normal diaplay kso isang beses sa bios lng pag pasok ng windows namamatay yung screen blinking na lng pilot light led, tried mg boot sa vga mode or safemode low res gamit nakakapasok when change ko ang resolution to 800x600 namamatay bat kaya ng kakaganito,

Ayun daming rerference na yan a... nice post sir mysti1
@TS sir follow question lang... normal na ba ung brightness nya?wala na mga sinabi mong diagonal lines(retrace lines) at ung original problem na "nagooverlap ung pictures"wala na rin.. Pero ang problema mo na ngayon e nawawala display pagdating sa windows logo?

Wag mong tapikin baka matuluyan, resolder yan pagnaging red na ng tuluyan try mong palitan ung video IC location nung ung IC na un ung board na nakakabit sa tube, nakakabit sya sa heat sink kaya madali lang makita.
