check mo po yung mga transistor sa CRT board pati na po mga resistor dun

check mo muna and compare yung voltages sa Cathode versus ground tatlo yun R G B if red ang video meaning either cra Transistor or cold solder lang sa Green at Blue cathode na nasa CRT board

focus ka muna sa CRT board malaman na jan ang sira...

check your RGB gun. if pareho sila ng voltage reading.. kung wala bang absence...
try also to check your 3 color driver transistor

check CRT circuit,madalas cold solder lang...

cold solder, nga madalas 3 time ko naexpirience. :-) pero 1 time sa tv ko resistor sa crt rin

oo nga sa resistor, minsan akong pinahirapan ng resistor sa crt board sa visual inspection mukha syang good nung mga 3 days ko hinahanap sira sinukat ko na isa isa ang mga resistor sa CRT board yun pala open yung isa yung nasa base ng transistor na nagreregulate sa red gun

hehe. ako masyado mababa na yung resistance.hehe

sa ibang tv kasi may switch para jan nakalagay sa crt. minsan switch lang din sa kakahanap ko wala akong mahanap inilagay ko sa gitna yung switch ayun ok na kulay.hehe

up
ok na po ba yung unit

ok na cguro, oh kaya........namumula na rin ang mata sa pangangapa.hehhe
btw, nasabi na lahat ng mga masters ang lahat ng maaring gawin mo.

share aku ulit may na-encounter akung SONY trinitron kanina lng tlaga, 29'' nga lang (^_^)

over red raster video din ang display.... check ko yung three RGB gun supply... hindi pantay ang nakuha kung reading.. hindi maadjust yung screen & sub-brightness adjustment..

trouble found: open resistor 680k ohm

hope makatulong yan

mga bos hanggang ngayn hin di pa rin gawa kasi tinbi ko muna, salamat sa inyong lahat try ko mga suggestion nyo

Woots29 · « **Reply #14 on:** June 15, 2009, 10:00:22 AM »

ako nmn CRT rejuvenator ang katapat.

nakaencounter ung isanga kasama ko ganyan

agree ako kay ultrasonic. 680k

tdh7700 · « **Reply #15 on:** June 15, 2009, 12:31:47 PM »

ako din naincounter ko green naman. 680k dn.
