JVC 21BA17B problem

Post by willyboy on Fri Oct 28, 2011 11:40 pm

mga brod.. patulong uli.. kasi yung JVC TV ko... sira din Laughing
pag nag on ka. red light indicator sa baba tv is on. but if you push any button, black screen pa rin, red light indicator is on, but you can hear ng tick tick, tick tick, tick tick ( parang trying to switch on and off )
then mawala yung tick sound. but if you push any button uli.. tick sound uli..

what is the possible cause kaya mga brod... patulong nman,, GOD bless !!! Laughing

mukhang may shorted kayong parts sa secondary willyboy. check mong maigi. ang horizontal output transistor mo baka shorted na. kong may zener diode ang tv mo na parang r2ks ang larawan. check mo din.

mga brod.. yung ticking on and off sa relay nawala.. kaso napunta naman yung tick sound sa FLYBACK.. wahhhhhh..lumipat lang,, paano kaya yun.. ok nman mga diode at transistor upon component testing..

yung board model e ito po :GG10041-001DH

subukan niyo palitan ang mga matataas na value na capacitor master sa horizontal malapit sa flybak. lalo na ang mga 1K6V. pag hindi nawala baka flybak na po iyan

mga brod..im back..nafree lang uli..nag change na ako ng mga capacitor sa tabi ng Flyback at yung horizontal tansistor nito pinalitan ko na rin ( yung katabi ng flyback)

pero ganun pa din...

when you turn on TV ( red light indicator is on )
but when you switch on channel. mag tick tick tick sound lang sya

pa assist nman uli mga..brod

sensya na ha.. di kasi ako tv tech..electromechanical line ko,, salamat po

mga brod..pasensya uli. pa ask lang..i have these color pink resistor
at mga 8pcs cla..
itong pink resistor na ito ay may printed kung ilang ohms sila or Kiloohms..

ang ask ko lang,i do have digital tester with sound. yung iba pag test ko with sound eh may tunog.. yung iba wala..

but if i switch on nman sa OHMS tester, lahat may reading..at tama sa printed ohms nito sa body.

ask kolang..kasi expert kayo d2. bakit yung iba eh may sound continuity at yung iba wala..aling ba dun angtama??

yung may sound??? or bka shorted yun
o yung wala?does it mean pag walang sound eh okyun.??

sensya mga tol..di ko linya tv repair pero talagang gustoko matuto nito..

salamat

ay master willy. baka hindi sila pareho ng value may color coded kasi ang mga resistor. http://www.ealnet.com/m-eal/resistor/resistor.htm
iyong mga mababa ang value gaya ng mga 1ohm. 5ohm 10ohm ay tutunog na iyan sa tester. ganyan ang tester ko na wheeler

ganun ba? bakit kaya ganun pa rin.napalitan ko nalahat capacitor sa primary atsecondary pati na rin satabi ng flyback..pati horizontal IC bago na rin..

pag on.,.led light on
thenpag pindotmo sa mga chanelor volume..you can hear tick sound..
3x tick sound

then wala nman display..nakailawparin yung on led light

hirap kasi akomagkuha ng voltahe eh..

any idea?

hanapin mu lng ang secondary filter capacitor, yan ang mgsisilbi mung test point

pra di maligaw hanapin mu lng ang pumapangalawa sa pnakamalaking capacitor sa board... na mlapit sa chopper transformer at may value na my working voltage na 160V or 250V. kdalasan value nyan ay 100uf, 220uf &etc.

eto sample pics JVC board din. CG chassis nga lng...
