i doubt na masosolve mo yan sis.. using caps lng.. kaelangan mo kasi na malakas na kuryente para matanggal ang weld sa loob.... pwde lng ang ganyan style kng boost color ang target mo... 50-50 nga lng ang chance mo jan na marepair ang kulay at maipangtay o mahabol sa iba sis... pwde masolve pwde din hndi.. pero hndi xa mkakapag worse sa unit... pwde na ang mga value na 2.2uf, 3.3uf at 4.7uf/250/400V. sa pggamit.. shunt/parallel mo lng sa Kx Gun (x-represent color gun like KR, KG, KB)  to ground ang caps ng around 4-6 seconds... depende na rin sau ilang seconds.. di nmn sensitebo yan... focus muna sa isang kulay... then release... kabit mo ulit ang caps sa Gun na un na pabaliktad nmn ang polarity ng caps... ingat lng ng kunti baka mashort mo ang ibang pins  ^_^  ... then sa ibang GUn namn....

sa ganyan style mga sis.. kng sobrang kapal ng kapit ng shorted Grid / weld grid nya sa loob ay di kakayanin ng DC stored ng caps... its better to rejuvinate using 450Vac.. medjo delikado nga lng... kasi pwde matuluyan ang picstube kasi my chance na maputol ang linya ng GUN

nung employee pa ako sa service center
may ginagamit kami na
pang tanggal ng short sa loob ng CRT (inter electrode short)
pwede DIY yun.
actually parang nakita ko na din sa web yung aparato na yun
basic transformer lang laman saka switch lang
iba ibang voltages.
