Sharp Cinemaborg 21V-G48 reception problem

Post by Jmark217 on Mon May 21, 2012 9:35 am

Mga boss patulong naman po sa tv ko.pag sobrang linaw ng reception ng channel nagugulo ang screen pero pag medyo malabo matino naman.ang isa pang problema nito ay hirap siyang marecieve ang channel 2 hanggang 5.malapit lang ang bahay ko sa isang FM radio station at napansin ko na pag off air yung station ay malinaw lahat ng channel. Dalawa ang tv ko at yung isa ay matino lahat channel kahit anong oras.
Dati po akong tv technician pero ngayong ay cellphone technician na ako at hindi na po ako updated sa mga trouble ng tv. Patulong naman po.salamat!

parang mahina ang agc o open grounding..
@TS na try mu ng e-resolder ang jungle area.. ?

try to replace small ecaps around AGC & IF block
subukan mu din mag shunt ng ceramic caps sa ilalim ng AGC/IF block.
markahan mu muna ang mga IFT mu bago mag adjust
