Sir paano po pag b protection lumalabas po ung unit ko po

[@marlonquismundo]

Sir same din ba ang sira ng LG BH6340H Bluray Home Theater kapag s-protection.

[@protechelectronics79]

Iba iba rin po ang nagiging dahilan kapag sa s-protection, minsan sa supply ng amplifier minsan nman sa mismong Amp. IC.

[@nikolamanza5856]

boss pwede po ba e test ang transistor na yan kahit hind na tanggalin sa board? baka kasi mali ang matanggal ko hirap pa naman mag solder ng maliliit na pyesa

Hindi kasi makukuha ang tamang reading kung nasa board.

Kadalasan pong nagiging problema kapag s protection ay kung walang supply ang amplifier at kung may supply nman sa mismong amplifier na ang sira.

[@prettypinkgamer4555]

Hi sir same lang ba yun pag hondi s protection nkalagay pero nag hehello then goodbye na agad sya?

[@mostafakazemi3120]

Ok. you replace the Q704 transiator with mosfet transistor and if dvd player have protection is right or board is fire? Because the protection is not work corectly

[@protechelectronics79]

The mosfet transistor that i replaced is not a protection transistor it is switching supply of amp. circuit, Unit was turned into s-protection because of that defective transistor.

[@alexesabedes9254]

Sir, same model po. Ang problem is mic input. Nadedetek na na naka mic in pero walang sound output ang mic. Everything else working. Tested ang mic cables and receivers on another speaker. Baka po alam nyo pano ifix? Salamat

[@protechelectronics79]

Gumagana rin po ba mic volume sa remote.

[@thomassichimata2596]

Engineer so mostly is the N- Channel MOSFET which causes S-Protection or Goodbye error in the DVD Home theater right or which other component can do that? pliz i have one DVD DH3140 doing the same ..Goodbye after some time when you swich on

[@protechelectronics79]

Missing supply voltage of amplifier or defective ic amplifier

[@jotors759210]

Hi sir meron ako fh6 d-protection naman ang na labas then mag off na sya... ano po kaya ang possibleng sira tnx

S-Protection is cause of defective amplifier and the only way to fix it is replace the baord
