Samsung 14" CT-3373V TV,no supply sa RGB done!
« on: January 15, 2010, 01:36:57 AM »
boss share ko lang po uli, ang problem wala kong masukat na voltages sa Cathode RGB, present ang B+,

Action taken: palit na ng IC, wala parin, so ginawa ko angat ko lahat ng resistors isang paa lang, isa-isa continuity
                   check, nahuli ko salarin, open 220k ohm na resistor na naka-connect sa IC, replace same value, done!

hope makatulong...To God be the Glory!

google chroma>>>;D ;D

any way sis medyo mahahabang paglalakbay ito kasi medyo di mo pa pla alam ang chroma at sytem yata...
medyo mahirap yan kapag medyo di natin alam ang mga basics...basa basa ka pa ng mga treds tungkol sa mga parts ng section ng tv..

pero ito bibigyan na kita ng mga halimbawa at mga tips for locating the section..
POWER SUPPLY-madalas nakakabit ang ac plug sa section na ito..dito makikita ang mga parts na malaking electrolytic capacitor na 400v ang working voltage..at nakasama narin dto ang regulator outpu(mdadalas ay ic ang nakakabit o transistorize depende sa model)opto coupler
SYSTEM CONTROL- isa itong ic na madalas malapit lamang sa location ng mga tak switches sya ang nagcocontrol ng mga keypad at nagseset ng mga setting at deafult
EEPROM-I2C-(inter-integrated circuit)
JUNGLE (chroma IC)-ito ang nagooscillate at naguutos ng mga color brightness,hsnc,vsync,hblanking ntsc/pal,etc...

yan lang muna.....research ka sis...
nasa chroma ic ang RGB out...madalas may nakaparallel na zener o signal diode jan at madalas sa mga sira ng rgb pag walang supply minsan ay shoted lamang ang mga diode na ito...
