check mo ang external damper diode malapit sa H-out... baka shorted... check na rin ang avalanche diode kung meron man ang ganyang unit..

papost na rin ang exact chassis.. look for TNPxxxxxx sa board

ako na ang sasagot. 30115 ay para sa 110v at iyang 50115 ay para sa 220v source. kong papalitan mo iyan ng ganyan. papalitan mo rin ang mga peripheral parts niya gaya ng main capacitor, varistor, start up cap at iba pa.

zener diode yan. Iyang tatlo colors ay color coding yan para makuha mo ang voltage reference niya.

pili ka lang ano ang ihihinang mo. halimbawa tanggalin ang pin 8 at turn on mo ang tv. then turn off naman para ibalik ulit ang tinanggal. pag walang pinagbago ay iyong negative pin naman. pagsabayin tanggalin ang pin 1,2,3, at 4. gayahin lang ang ginawa sa positive pin. pag ganun pa rin ay kailangan mo na talagang ireprogram ang eeprom sapagkat hindi umuubra ang pag reset

H57 pwde H size meaning nyan kaya nasa Smode ka. try press menu para mag exit. pwede ring baka High Frequency Channel na naka manual fine tune... hindi familiar sakin ang Eboard.. duda akong naka matrix na yan... kung sakali man ts.. try hinang ang mga tact switch at remocon ang gamitin...

Ngpalit na nga ako ng mga tact switch ne2 at minsan ng iiba ng function. D ko pa e2 ntry ng oras n buhay ang tv. Cguro mga khahating oras n mtagal. Pero pg on ko at dumisplay un H57 d ntagal na automatic off. Panu kaya mka exit kung nsa s-mode e2. Ska kung my nbago man pwd ko pa kya maibalik sa dati settings? Ask ko lng sir ultra kung panu mpasok ang s-mode ne2. Bka pwd rin mkhnge copy ng orgnal settings. Dagdag ktanungan nrin, normal b na ng iinit un ibang ecap? 2lad nlng nun 1000/25v sa vertical section. Abang nlng ako sa mga advice nyo. Tnx..

hindi normal ang uminit... try mo check sa ESR yang caps na yan... or maaaring mataas ang V supply jan. check mong maigi ang rectifier diode niya.. pag leak iyan o shorted pwde yang makapagpasabog ng ecaps...

btw.. mas duda ako sa eeprom data.. malamang nabago nga yan. lalot nagkaroon ng symptoms ng mga error command galing tacts sw.. sad to say wala akong exact data parameter nyan sis... pero try natin baka my dump tau ng pwde isampak dyan... post mo nlng muna ang mga major parts nyan...
sa pag exit press menu nlng muna sa remote con...
