Update lang....

Ginawa ko po mga sinabi nyo master... eto po yung resulta...

Hang B+ pin..... ganun pa din ang resulta....

Hang input pin ng 9v reg..... naging stable lahat ng available voltages....

Check ko ulit ABL circuit... may nakita me na dalawang switching diode na MA113 surface mount may reading both sides off circuit... walang mahanap na katulad na piyesa kaya 4148 na lang kinabit ko (sabi nung binilhan ko dito)... resulta... ganun pa rin....

Tanong master... Ok lang po ba ang 4148 na pamalit sa MA113?

Just want to confirm kung jungle nga ba ang problem ng tv..... Kung sino po sa inyo ung merong TDA8375A... pwede nyo po ba makukuhanan ang resistance between pin 44 and pin 12 ng IC out of circuit kung ilan ung reading?... doubt  duda kasi me baka shorted na ang supply ng IC with respect to ground...

Salamat po sa lahat in advance!!!

Isa-isang pag check master.... halos isang buwan din siguro inabot ko dito... hirap kasi... chip type kasi ung iba... una kong nakita ung open na resistor tapos ung 2 diode sa ABL circuit... tapos nung pinalitan na wala pa rin kaya nung isolate ko mga supply doon ko na nakita si jungle na ang may tama... bangungot nga to... muntik ko ng ibalik sa may-ari... buti nandidito kayo....
