Hindi ka lang dapat naka check sa transistor. Dapat ang transistor last check mo na yan. Tanggalin mo muna transistors tapos icheck mo if there are shorted capacitors. Then Check mo ic. Then check mo print head. Saka mo ikabit yung transistor. Then if hindi namatay saka mo ikabit yung fuse.

[@richardpadron9564]

Kapag nasira ang transistor meaning sira na din ang head, at sira na din ang IC, pag nagpalit ka ng transistor always set yan with IC at printhead.

[@UCZLwrZkJax0LEsPLmjkJgpg]

Yes sir grounded na ang head nya

[@UCZLwrZkJax0LEsPLmjkJgpg]

First pag sira na head nean una nang maga breakdown ang
1. fuse nya then pag nag jumper tayo ang sisirain nya naman ai
2. transistor at
3. power IC.

[@tyrellwreleck4226]

There is a way to check the print head. If OL yung last pin ng print head(ground) dun sa first 3 pins then okay pa ang print head. Hindi basta basta nasisira ang print head unless ginamitan mo ng malakas na force para ma unclogged.
Pag nasira ang print head, pumuputok lang ang fuse.

@@tyrellwreleck4226 diba sir dapat yong first pin lang OL at yong dalawang pin na kasunod may reading...

[@yurrichan1553]

parang mas okay nalang boss bumili ng bago yawa hahaha

[@brianjayarado]

Bossing nakita ko pag nagpalit ka mosfet palit din power ic.. other wise hindi talaga gagana.. if mosfet lang pwede gumana pero patay ulit,,

[@kemalisk4327]

merhaba aynı sorun bende mevcut transitörleri yakıyor sorun ıc E09a92ga olabilir mi

[@UCZLwrZkJax0LEsPLmjkJgpg]

Yes sir if yoy change the transistor please include the power IC also it very sensistive one mess short the ic and transistor

pwede ba boss gamitin walang transistor?

[@jaysonrasonabe9114]

Dapat kasi pag bumigay yata sir ang resistor matik palit power IC

[@UCZLwrZkJax0LEsPLmjkJgpg]

Yes kaso ang hirap ma trace ang short nakapagud hehhehe

[@tyrellwreleck4226]

@@UCZLwrZkJax0LEsPLmjkJgpg Madali lang matrace ang short. Ang problema mahirap magpalit ng caps at resistors kasi wala tayong schematic value ng mga components.

[@JhaysonYT]

Mas okay po ba na bumili na lang ng bagong board if ever sira na talaga?

[@UCZLwrZkJax0LEsPLmjkJgpg]

Yes sir kaso both ang papalitan jaan kailangan e check ang printhead useless din pag brand new ang boarf bago short ang printhead waste money

Ser magkano paayus NG bird NG epsonL121

[@UCZLwrZkJax0LEsPLmjkJgpg]

Hindi ko kaya mag repair Ng board dahil very sensitive pag may short na pyesa hirap din e test Isa Isa replace nyo nalang po make sure Ang print head baka pag new board tapos short Ang printhead sira din Ang new board.

[@ramilimpang276]

sabi mo sira ang transistor, nong na check mo na ok ang puse sabi mo ok ang transistor hindi sira ano ba talaga?

[@UCZLwrZkJax0LEsPLmjkJgpg]

Kalma lang kua

[@EngineeringStudent06]

May link ka lods kung saan nabili

[@UCZLwrZkJax0LEsPLmjkJgpg]

Ah ok try ko hanapin

[@ramilimpang276]

makalilito

[@UCZLwrZkJax0LEsPLmjkJgpg]

Sira transistor, pinalitan ko nasira ulit, dahil pag nasira Ang transistor sira nadin Ang power ic kaya kung mag papalit ka Ng transistor dapat Kasama na power ic Kasi masilan yang mga logic board pag short na dispose Muna magagastusan ka lang dahil mahirap ma trace kung alin pa Ang short depende sa nangyari dedepende po, halimbawa nataihan Ng ipis, ihi Ng daga nabasa Ng tubig nasundot Ng screw HABANG nag babaklas madame possible ok po gets na salamat sa support.

[@bulawanongigsuonvlog]

Sir

[@UCZLwrZkJax0LEsPLmjkJgpg]

Yes po

[@the13thkind27]

Yan ang mahirap sa epson lalo na mga L series masyado masilan... Automatic yan kapag sira dalawang MOSFETs sira ang ic at palit ng print head parang yan na ang pinaka SOP sa epson logic board... Di pwdng mosfets lang papalitan kasama lagi ic jan pati flex cable...

[@UCZLwrZkJax0LEsPLmjkJgpg]

Yes true grabe kaya double ingat talaga very expensive ang iten
