sir..tama si bossing..na experience ko yan nung nag trouble ako sa TCL problem..

una problem..horizontal line lang sa center.. double Line ngalang..
nung nagpalit ako ng resistor at capacitor IC ng VERTICAl IC301
R306A na47kat ecapsC305 na2.2/50V ayun naOK..

pero may thin Line naman sa taas( like your problem)..nagpalit lang akoEcaps saVCCng Vertical IC (c308 with valueof 100UF/35V) ayun ok na..

as of Now..Buhayparin TCL ko.. lol!

yapz possible din. pero kunti lng ang chances

jejejeje patient ang kailangan mu jan
check mu lng maigi ang mga peripheral parts ng Vert. zander
resist, caps at diode

^ uu nga sis arkin.. kya nga pinapa aware ko na normal sa Sony ang ganyan (^_^

triac wrote:pati ako nahihirapan..sir ultra paano ba malalaman ang protection circuit?

hhmmmpppff bwat model at chassis my knya kanyang Prot.... at tawag din.. sa sobrang dami ng TV models bka di natin ma tackle...
kya focus nlng muna tau sa Sony lalot sony itong tnutrouble ni TS... (^_^

mostly sa mga Sony lalot mga GMR series ba yun, di ko na malaala.. my mga resistor na 1/8W na nkaseries sa secondary B+ line.. kng susundan mu yun ay dadalhin ka nyan sa iba ibang Protection circuit.. try to float or condemn them. pg gumana. expect na nandoon sa section na un ang my problema. expect din na pwde my umusok o pumutok. pwde nyu din gamitin ang SONY BLINKING CODE as a guidelines sa troubleshooting nyu.. but dont expect too much.. kasi pg my problema ang system con/cpu/mcu.. di na yan susunod sa Code...

sa Xray Protection nmn.. its a form of HV mylar caps na nka connect sa B+ hnggang Collector pin ng HOT...

for Video muting, mostly sa mga lumang modelo ng Sony my IK return sa C board hanggang Jungle/Chrome.. try to condemn them by cutting & put signal diode back to Chroma. parang ganito...





read more

sa ibang modelo wlang silang IK circuit.. iba ang protection nila... white balance scanner tawag ng iba... ah basta madamo pa jud...

sa audio nmn.. for the sound muting.. alam nyu na yata ito... look for the datasheets nlng at alamin ang mute pin ng sound ic.. mostly transistorize ang switching nito...

for the tuner.. look scl & sda at supply ng 33v

for ABL sundan lng ang FBT pin... its a form of resistor & zeners

yan nlng muna
sana mkatulong (^_^


btw i forgot to tell na ang protection circuit ay hindi para lituhin ang technician, ito ay protection ng Manufacturer to avoid more worse/damage sa Unit nila...

ur welcome sis... share share lng po tau for the benefits of the new generation (^_^

btw for some other model... kng IK protection at white balance Prot ang tawag sa knila.. Discharge Protection Ckt at Spot killer circuit naman ang tawag namin sa LG
