Sharp color TV model 14V-N42 , normal sound, screen problem
« on: January 16, 2010, 08:36:39 PM »
Mga master pa help dito sa Sharp tv, old model na pero baka pwede pa. :)

History po nito nagpalit crt socket. So Ok na sya iniuwi na ng may ari.

 After 4days bumalik pumutok ang flyback.

Sa Raon 1T plus daw ung orig na flyback ....
dahil nga luma na TV kaya ung "replacement" ang kinuha worth 300 lang.
 


Eto po ung flyback naikabit na (F0065)

Ang problema po ay sobra ung boltahe sa screen 700 na ung namemeasure.
So sobra liwanag picture hindi na maaninag ung palabas.
Nakasagad down na ung screen control. at may arcing pa sa CRT socket.


Mga master pa help. May problema kaya flyback o may iba pa trouble?
Ask ko opinion nyo bago tuloy troubleshooting bukas,
 Thanks in advance. :)

Mga kosa salamat sa mga advice acknowledge lahat...

Sira talaga ung flyback.
So ginawan na lang paraan... nagdagdag na lang trimmer sa linya para idrop ung boltahe.





Eto na ung TV normal na picture.

Ang tanong lang e kung magtatagal... so under observation pa.

Tama si sir  marcial... kahit ano value basta mataas dapat meg ung trimmer (ang kinabit namin bunot galing sa crt ckt, ung ginamit ng old model na sony )
simple lang ung ginawa... bago dumiretso ung screen (orange wire galing flyback) sa Crt crkt e pinadaan sa trimmer na may nakakabit na resistor papuntang ground.
