kolin21mke11 alway fine tuning...

Post by baddypepito on Wed Nov 07, 2012 11:36 pm

hello po sa lahat... meron po akong kolin 21'' tv na narepair. yong problema nya ay lge mo syang ipafine tuning in every channel. every lipat po ng channel ay ifine tune in order ro obatain a clearer signal... at saka in every channel lge sya sa +16 position ng fine tuning. ano kaya ang salarin nito? nasubukan ko ng ichange ang jungle,system at tuner. try ko din sa memory pro wla pa rin. pero kpag nfine na sya wala talagang problema sa kanyang picture at audio.its working perfectly. pro kung lilipat sa ibang channel,ayan fine na naman. para ding hindi nya matandaan yong mga channels na nafine nya. what could be the possible cause? wanafight

less ang suspect ko nito sa eeprom kasi dependot pa ang fine tune nito... malinaw pag naka holdpress-on ang fine tune.. lalabo nmn pag bnitawan or sa normal viewing? tama ba ang pgkakaintindi ko sis... ?

pwdeng weak VCO eto or other reasons sa mga IF stages
pero tanong ko lng eto ba iyong malalaki ang tuner module na nkabukod na SIF, crystal Saw filter & etc... ?
try mu yang baklasin sis... at resolder sa bandang IFT.. pag no improvement baklasin ang IFT at hanapin kng anong pin ang my built in capacitor.. pwede mung palitan iyong ng panibagong ceramic caps.. or pwde mung parallelan mo na agad without tanggalan ^_^

kng my pamalit kang Tuner mas mainam para mas maconclude mu agad

ito nga pala ang tuner number nya... TECC1070PG26B... tapos ko na pung magpalit ng tuner, ganun pa rin. ang history: binili ko ang unit na ito... nong una ay sira ang kanyang coupler sa smps. nang gumana na sya,lahat ng channels ay wala talagang macapture. i decided to replace tuner ay ganun pa rin. nang mareplace ko na ang kanyang I.F meron na syang makukuha kaya nga lang ay malabo. at ito na ang problemang ito. always mong ifine tune... suspected ko talaga ang kanyang I.F. baka hindi perfect ang kanyang pagkakaalign.

parang 33pf ceramic iyon. di lng ako sure kasi di ko maalaala ang exact value... bastat nasa range iyan ng pf

you can trial & error nlng... subukan mu lhat na available na ceramic sa market ito lng nmn ang commercial available...
1, 5, 10, 12, 15, 20, 22, 25, 30, 33, 39, 47, 50, 68, 82,100, 120, 150pf. mura lng nmn iyan .50 cent ang isa

minsan ito ang bases ko: SIF= 2 to 30pf VIF= 2 to 15pf
pero we cannot assure this kasi naka built in pa rin ang tubular caps sa ift na nasa ilalim. mpanganib di itong tanggalin bka mgkamali kau ang maputol ang windings... kya minsan shunt/parallel nlng ng ceramic caps sa kanya...
kng anung value ng caps ang napakalapit sa pinakamalinaw ay yan ang ilagay mu sis

natry ko na sis.... unfortunately ganun pa rin.. but meron akong napansin.. everytime na magalaw ko ang kanyang i.f ay nag-iina din ang position ng fine tuning number.. hinala ko talga na sa i.f lang ito. hindi perfect ang kanyang alignment... tama kaya nag pagkaintindi ko?

nalito ako sa thread. SONY yata tinutukoy mo nyan sir. KOLIN po ito at hindi sony pinting super laughping

@baddypepito congratulations
maaari din may problema lang ito sa data at kailangan manual ang pag set sa service mode

Code:
Kolin TV Service Mode
Chassis    Remote codes    To exit
I-Chassis    SLEEP-MUTE-DSP-MENU    DSP or SLEEP
K-Chassis    SLEEP-PIC-DSP-MENU. Press MENU to navigate pages.    SLEEP
M-Chassis    DSP-SLEEP-PIC. To select adjustment menu use CH+/CH- buttons. To enter the adjustment menus, use VOL+/VOL-    MENU       

Before doing adjustments, list down the adjustment items and their corresponding data so you can return the data to previous settings in case the new settings result to more problems.
