Post by bjohn798 on Mon Mar 12, 2012 11:40 pm

pa help po schematic diagram of sony trinitron model KV-14GP1. nag totrouble shoot po ako kaso hindi ko mabasa ang nakasulat sa board kc chinese or japanese ata tong nakasulat hehe. galing na po ito sa ilang mga shop, pagdala nito dito sa akin ay ung h-out ay hindi na naka solda sa board pag test ko dito ay short na. at sabi sa mga shop na pinag dalhan nito ay palitan nalang daw natin to ng universal board.

may 3 led indicator po ito. ung pinakababa na led indicator nya ay nag biblink kung isinsksak ang plug sa outlet at pag hinugot ung plug sa outlet ay nag biblink din, pwo isang blink lang nman hindi continues.

at tsaka pag tinanggal ko yung crt board sa picture tube at e on ko ang main switch, nag bi-blink naman yung nasa taas na led indicator which is color green na LED

kng ganyang problema,dpat plitan na picturetube.my ibang model ng sony na ganyan din ang problema,pro hindi nmamatay.kya lng,nasisira yong H. out transistor or ang R2M kong pinapatay yong tv.dilikado na rin yan.
