gamitan mu ng sense of touch.. pakiramdam ang HOT during & after operation. pag madaling umiinit na halos di mahawakan ay alam mu na ang gagawin mu lol!

kng with damper diode yang orig ay pwpwede na jan ang D1877, D1878 & etc...

ah ok..,ginawa ko na rin yun master..,parang ok naman.,normal ang init ng heatsink..,so siguro lagyan ko nalang ng damper..,salamat..

sir ultra diba iyong mga nagsisimula sa letrang C ay NPN transistor ito, pero walang internal damper diode. di tulad nung may D na may damper diode na.. kong HOT na nagsisimula sa D ang ikakabit niya ay dapat sigurong tanggalin niya iyong damper diode sa board

yapz tamang tama ang sagot mu hertz. yan ang isa sa mga rason kng bkit masisibakan ulit. double damping diodes ;D

btw welcome back.. Razz

uu nga pla di ko nareview ng maigi ang post ni TS..
C5480 pala ang orig meaning wlng damper


@140__x13r anu nga palang chassis yan ng mahatulan natin.
kng yan ba tlga ang orig HOT nyan...

sony kv-25dr1 japan surplus

sony 1-674-287-23?wala iba nakalagay kundi yan lang..,yan na ba yun.. Rolling Eyes

wala ako makita iba..,kung hindi yan..,di ko malocate..,walana po nakalagay..


thanks sa mga reply...

walang damper ? No check mo nga ultra ang datasheet C5480.
iyan na nga ba ang sinasabi ko sayo. wag agad magsalita pag hindi sigurado

Those days when i started my electronics course, i was exposed to only few standard codes for transistors. It is either the European or the Japanese code. That means when you see a transistor part number it can be either C3039 or 2SC3039. Both the part numbers are the same and can be used in the equipment. The main difference is only in the code. The European code starts with C (for NPN transistor) and the Japanese code starts with 2SC. It was quite easy to identify whether the transistor belongs to NPN, PNP, Fet, Triac, SCR and etc. We as repair tech have no problem in identifying them.

Since there are so many semiconductor manufacturers in the world nowadays, lots of them never follow the standard transistor coding anymore. They came out with many funny numbers (codes) and even finding the internet could hardly locate what type of transistor it was. Because of this, it gave lots of headache to electronics repairers around the world. Just imagine you found a shorted device (all legs have reading when check with meter) that have the look of a transistor (3 pins) with the part number of ZBD689A1 and you do not have the schematic or even data sheet. In what way you will know this 3 leg device whether it is a bipolar transistor, FET, SCR, Triac and etc ? A wrong guess will consume your repair time and sometimes it may burn other components too in the equipment.

Lets take another example, if you repair CRT Monitor you will definitely came across HORIZONTAL OUTPUT TRANSISTOR (HOT). Fairchild semiconductor came out HOT with the part number that start with “J” like the J6810 and etc. If you are new in this repair field, you may have thought that it was a P-channel Mosfet because according to standard code a P-channel Mosfet part number will start with J or 2SJ!

If all the manufacturers could follow the standard transistor coding, then we will have less problem in identifying them.

aw sori sir... tao lng lol!

may damper nga

peace ,,V,(^_^)

sana palay sinilip ko nlng sa database.. si hertz kasi.. napa Oo tuloy aku pale


@140__x13r defende kasi yan sa manufacturer ng devices. minsan iba iba ang transistor code na gnagamit.. but most of the tym... yang C lalot kng Sony ay tranny lng tlga.. kayat napa Oo agad aku. btw pero pag di familiar mas xure kng mg based nlng tlga sa datasheets.

xa nga pla sis.. yang bang chassis board na yan ay wlng HDT gnagamit ? di ko mavisualize ang modelong yan

gumagana pa yung unit ko pero pinalitan ko na rin ng same sa original value..,

pero..,namatay apologies after 15 lang yata gumana..,
tsek ko ulikung anu cause..sinarado ko na kasi unit..
japeke yata nabili ko sa newport..

parang sis..nung kinabit ko yung bago na c5480.,10 mins lang yata gumana..,nasibak agad...


kaya ito binalik ko na lang yung 1402..,ilang oras na nakabukas mula kahapon pa konagtetest..,buo pa ang unit hanggang ngayun at normal naman ang init sa heatsink..

concluded siguro..,japeke nga yun..

Siguro nga or..kailangan na talaga ng replacement na mas mataas ang rating,.para di madali masibak..

Eto,.,gumagana pa namanang unit hanggang ngayun.
